Elasticversion - 1.7.6
springboot - 1.3.5
Using spring-data-elasticsearch I have created a custom JSON mapping as advised elsewhere in order to support Java8 new datetime fields.
This works fine - but breaks reading entities from the repository as the id field no longer gets populated.
CustomConfig:
#Bean
#Autowired
public ElasticsearchTemplate elasticsearchTemplate(Client client) {
ObjectMapper objectMapper = new ObjectMapper();
objectMapper.registerModule(new JavaTimeModule());
return new ElasticsearchTemplate(client, new CustomEntityMapper(objectMapper));
}
public class CustomEntityMapper implements EntityMapper {
private ObjectMapper objectMapper;
public CustomEntityMapper(ObjectMapper objectMapper) {
this.objectMapper = objectMapper;
objectMapper.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false);
objectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
objectMapper.configure(DeserializationFeature.ACCEPT_SINGLE_VALUE_AS_ARRAY, true);
}
#Override
public String mapToString(Object object) throws IOException {
return objectMapper.writeValueAsString(object);
}
#Override
public <T> T mapToObject(String source, Class<T> clazz) throws IOException {
return objectMapper.readValue(source, clazz);
}
}
Sample Entity :
#Document(indexName = "scanner", type = "Entry")
#Data
#Builder
#NoArgsConstructor
#AllArgsConstructor
public class Entry {
#Id
private String id;
#Field(type= FieldType.String)
private String path;
#Field(type = FieldType.Date, format = DateFormat.date_time )
private OffsetDateTime created;
}
Note - that when I remove the CustomEntityMapper the id field is returned. I have traced the spring-data-elasticsearch code,
and identified that it fails to resolve the Id field from the elastic response in DefaultResultMapper.setPersistentId since
the mappingContext is null.
private <T> void setPersistentEntityId(T result, String id, Class<T> clazz) {
if (mappingContext != null && clazz.isAnnotationPresent(Document.class)) {
PersistentProperty<ElasticsearchPersistentProperty> idProperty = mappingContext.getPersistentEntity(clazz).getIdProperty();
// Only deal with String because ES generated Ids are strings !
if (idProperty != null && idProperty.getType().isAssignableFrom(String.class)) {
Method setter = idProperty.getSetter();
if (setter != null) {
try {
setter.invoke(result, id);
} catch (Throwable t) {
t.printStackTrace();
}
}
}
}
}
Has anyone experienced this issue? How can I support a CustomEntityMapper without breaking the Id resolution?
upgrading to spring boot 1.4.1-RELEASE resolved the issue

I'm working on making a custom properties provider to load the contents of a Spring cloud config server at startup. I need to make a single call at the initialization of the provider to fetch these properties, and would like to use the Mule HttpService in order to make the http client for this call, instead of creating my own. Unfortunately, whenever I try this, it seems the HttpService hasn't been created yet and so throws an NPE once it's referenced.
CustomConfigurationPropertiesProviderFactory.java
public class CustomConfigurationPropertiesProviderFactory implements ConfigurationPropertiesProviderFactory {
public static final String EXTENSION_NAMESPACE = "custom-properties";
public static final String CONFIGURATION_PROPERTIES_ELEMENT = "config";
public static final ComponentIdentifier CUSTOM_CONFIGURATION_PROPERTIES =
builder().namespace(EXTENSION_NAMESPACE).name(CONFIGURATION_PROPERTIES_ELEMENT).build();
#Inject
HttpService httpService;
#Override
public ComponentIdentifier getSupportedComponentIdentifier() {
return CUSTOM_CONFIGURATION_PROPERTIES;
}
#Override
public ConfigurationPropertiesProvider createProvider(ConfigurationParameters parameters,
ResourceProvider externalResourceProvider) {
String url = parameters.getStringParameter("url");
return new CustomConfigurationPropertiesProvider(url, httpService);
}
}
CustomConfigurationPropertiesProvider.java
public class CustomConfigurationPropertiesProvider implements ConfigurationPropertiesProvider {
private final static String PREFIX = "custom::";
private Properties properties = null;
public CustomConfigurationPropertiesProvider(String url, HttpService httpService) {
HttpClientConfiguration.Builder builder = new HttpClientConfiguration.Builder();
builder.setName("customProperties");
HttpClient client = httpService.getClientFactory().create(builder.build()); //NPE here
client.start();
// proceed to create and execute request, then load into properties
}
#Override
public Optional<ConfigurationProperty> getConfigurationProperty(String configurationAttributeKey) {
if (configurationAttributeKey.startsWith(PREFIX)) {
String effectiveKey = configurationAttributeKey.substring(PREFIX.length());
if (properties != null && !properties.isEmpty()) {
return Optional.of(new ConfigurationProperty() {
#Override
public Object getSource() {...}
#Override
public Object getRawValue() { return properties.getProperty(effectiveKey); }
#Override
public String getKey() { return effectiveKey; }
});
}
}
return Optional.empty();
}
}
What do I need to change to properly inject this service?
I've been following the advice from these two bits of documentation, for reference:
https://docs.mulesoft.com/mule-runtime/4.2/custom-configuration-properties-provider
https://docs.mulesoft.com/mule-sdk/1.1/mule-service-injection
As I'm using ResponseEntity<T> as return value for my FeignClient method, I was expecting it to return a ResponseEntity with 400 status if it's what the server returns. But instead it throws a FeignException.
How can I get a proper ResponseEntity instead of an Exception from FeignClient ?
Here is my FeignClient:
#FeignClient(value = "uaa", configuration = OauthFeignClient.Conf.class)
public interface OauthFeignClient {
#RequestMapping(
value = "/oauth/token",
method = RequestMethod.POST,
consumes = MULTIPART_FORM_DATA_VALUE,
produces = APPLICATION_JSON_VALUE)
ResponseEntity<OauthTokenResponse> token(Map<String, ?> formParams);
class Conf {
#Value("${oauth.client.password}")
String oauthClientPassword;
#Bean
public Encoder feignFormEncoder() {
return new SpringFormEncoder();
}
#Bean
public Contract feignContract() {
return new SpringMvcContract();
}
#Bean
public BasicAuthRequestInterceptor basicAuthRequestInterceptor() {
return new BasicAuthRequestInterceptor("web-client", oauthClientPassword);
}
}
}
and here how I use it:
#PostMapping("/login")
public ResponseEntity<LoginTokenPair> getTokens(#RequestBody #Valid LoginRequest userCredentials) {
Map<String, String> formData = new HashMap<>();
ResponseEntity<OauthTokenResponse> response = oauthFeignClient.token(formData);
//code never reached if contacted service returns a 400
...
}
By the way, solution I gave before works, but my initial intention is bad idea: an error is an error and should not be handled on nominal flow. Throwing an exception, like Feign does, and handling it with an #ExceptionHandler is a better way to go in Spring MVC world.
So two solutions:
add an #ExceptionHandler for FeignException
configure the FeignClient with an ErrorDecoder to translate the error in an Exception your business layer knows about (and already provide #ExceptionHandler for)
I prefer second solution because received error message structure is likely to change from a client to an other, so you can extract finer grained data from those error with a per-client error decoding.
FeignClient with conf (sorry for the noise introduced by feign-form)
#FeignClient(value = "uaa", configuration = OauthFeignClient.Config.class)
public interface OauthFeignClient {
#RequestMapping(
value = "/oauth/token",
method = RequestMethod.POST,
consumes = MULTIPART_FORM_DATA_VALUE,
produces = APPLICATION_JSON_VALUE)
DefaultOAuth2AccessToken token(Map<String, ?> formParams);
#Configuration
class Config {
#Value("${oauth.client.password}")
String oauthClientPassword;
#Autowired
private ObjectFactory<HttpMessageConverters> messageConverters;
#Bean
public Encoder feignFormEncoder() {
return new SpringFormEncoder(new SpringEncoder(messageConverters));
}
#Bean
public Decoder springDecoder() {
return new ResponseEntityDecoder(new SpringDecoder(messageConverters));
}
#Bean
public Contract feignContract() {
return new SpringMvcContract();
}
#Bean
public BasicAuthRequestInterceptor basicAuthRequestInterceptor() {
return new BasicAuthRequestInterceptor("web-client", oauthClientPassword);
}
#Bean
public ErrorDecoder uaaErrorDecoder(Decoder decoder) {

OAuth2Exception uaaException = (OAuth2Exception) decoder.decode(response, OAuth2Exception.class);
return new SroException(
uaaException.getHttpErrorCode(),
uaaException.getOAuth2ErrorCode(),
Arrays.asList(uaaException.getSummary()));
} catch (Exception e) {
return new SroException(
response.status(),
"Authorization server responded with " + response.status() + " but failed to parse error payload",

};
}
}

Feign client usage notice how errors are transparently handled (no try / catch) thanks to #ControllerAdvice & #ExceptionHandler({SroException.class})
#RestController

#Autowired
public AuthenticationController(
OauthFeignClient oauthFeignClient,
#Value("${oauth.ttl.refresh-token}") int refreshTokenValidity) {
this.oauthFeignClient = oauthFeignClient;
this.refreshTokenValidity = refreshTokenValidity;
}
#PostMapping("/login")
public ResponseEntity<LoginTokenPair> getTokens(#RequestBody #Valid LoginRequest userCredentials) {
Map<String, String> formData = new HashMap<>();
formData.put("grant_type", "password");
formData.put("client_id", "web-client");
formData.put("username", userCredentials.username);
formData.put("password", userCredentials.password);
formData.put("scope", "openid");
DefaultOAuth2AccessToken response = oauthFeignClient.token(formData);
return ResponseEntity.ok(new LoginTokenPair(
new BearerToken(response.getValue(), response.getExpiresIn()),
new BearerToken(response.getRefreshToken().getValue(), refreshTokenValidity)));
}
#PostMapping("/logout")
public ResponseEntity<LoginTokenPair> revokeTokens() {
return ResponseEntity
.ok(new LoginTokenPair(REVOCATION_TOKEN, REVOCATION_TOKEN));
}
#PostMapping("/refresh")
public ResponseEntity<BearerToken> refreshToken(#RequestHeader("refresh_token") String refresh_token) {
Map<String, String> formData = new HashMap<>();
formData.put("grant_type", "refresh_token");
formData.put("client_id", "web-client");
formData.put("refresh_token", refresh_token);
formData.put("scope", "openid");
DefaultOAuth2AccessToken response = oauthFeignClient.token(formData);
return ResponseEntity.ok(new BearerToken(response.getValue(), response.getExpiresIn()));
}
}
So, looking at source code, it seams that only solution is actually using feign.Response as return type for FeignClient methods and hand decoding the body with something like new ObjectMapper().readValue(response.body().asReader(), clazz) (with a guard on 2xx status of course because for error statuses, it's very likely that body is an error description and not a valid payload ;).
This makes possible to extract and forward status, header, body, etc. even if status is not in 2xx range.
Edit:
Here is a way to forward status, headers and mapped JSON body (if possible):
public static class JsonFeignResponseHelper {
private final ObjectMapper json = new ObjectMapper();
public <T> Optional<T> decode(Response response, Class<T> clazz) {
if(response.status() >= 200 && response.status() < 300) {
try {
return Optional.of(json.readValue(response.body().asReader(), clazz));
} catch(IOException e) {
return Optional.empty();
}
} else {
return Optional.empty();
}
}
public <T, U> ResponseEntity<U> toResponseEntity(Response response, Class<T> clazz, Function<? super T, ? extends U> mapper) {
Optional<U> payload = decode(response, clazz).map(mapper);
return new ResponseEntity(
payload.orElse(null),//didn't find a way to feed body with original content if payload is empty
convertHeaders(response.headers()),
HttpStatus.valueOf(response.status()));
}
public MultiValueMap<String, String> convertHeaders(Map<String, Collection<String>> responseHeaders) {
MultiValueMap<String, String> responseEntityHeaders = new LinkedMultiValueMap<>();
responseHeaders.entrySet().stream().forEach(e ->
responseEntityHeaders.put(e.getKey(), new ArrayList<>(e.getValue())));
return responseEntityHeaders;
}
}
that can be used as follow:
#PostMapping("/login")
public ResponseEntity<LoginTokenPair> getTokens(#RequestBody #Valid LoginRequest userCredentials) throws IOException {
Response response = oauthFeignClient.token();
return feignHelper.toResponseEntity(
response,
OauthTokenResponse.class,
oauthTokenResponse -> new LoginTokenPair(
new BearerToken(oauthTokenResponse.access_token, oauthTokenResponse.expires_in),
new BearerToken(oauthTokenResponse.refresh_token, refreshTokenValidity)));
}
This saves headers and status code, but error message is lost :/
i'm using spring-boot-starter-data-elasticsearch (1.4.0.M3).
I'm unable to get the version (_version in elasticsearch query result) of a document using the annoation "version".
Any idea why the annotation isn't working ?
f.e.:
#GwtCompatible
#Document(indexName = "myIndexName")
public class Catalog implements Serializable {
private List<GroupProduct> groups;
#Id
private String uuid;
#Version
private Long version;
#Field(type = FieldType.Nested)
private List<Product> products;
private String label;
#NotEmpty
private String organizationUuid;
private List<String> organizationUnitUuids;
private Date updateDate;
private List<VAT> vats;
public Catalog() {
}
public List<GroupProduct> getGroups() {
return groups;
}
public List<Product> getProducts() {
return products;
}
public Date getUpdateDate() {
return updateDate;
}
public void setGroups(List<GroupProduct> groups) {
this.groups = groups;
}
public void setProducts(List<Product> products) {
this.products = products;
}
public void setUpdateDate(Date updateDate) {
this.updateDate = updateDate;
}
public List<VAT> getVats() {
return vats;
}
public void setVats(List<VAT> vats) {
this.vats = vats;
}
public String getUuid() {
return uuid;
}
public void setUuid(String uuid) {
this.uuid = uuid;
}
public String getOrganizationUuid() {
return organizationUuid;
}
public void setOrganizationUuid(String organizationUuid) {
this.organizationUuid = organizationUuid;
}
public String getLabel() {
return label;
}
public void setLabel(String label) {
this.label = label;
}
public List<String> getOrganizationUnitUuids() {
return organizationUnitUuids;
}
public void setOrganizationUnitUuids(List<String> organizationUnitUuids) {
this.organizationUnitUuids = organizationUnitUuids;
}
public Long getVersion() {
return version;
}
public void setVersion(Long version) {
this.version = version;
}
}
Spring Data Elasticsearch (as of version 2.0.2) seems to have only partial support for the #Version annotation. If you annotate a document with a version field, it will be used when indexing a document. It will tell Elasticsearch that the document being saved is that specified version. If the new version is less than or equal to the version of the current document, Elasticsearch will throw a VersionConflictEngineException.
Unfortunately, Spring does not appear to populate this version field when a document is retrieved. As far as I can tell, this makes the version annotation useless. Perhaps the project will add this support in the near future. In the meantime, I have found a workaround by extending the default ResultMapper that Spring uses:
public class ExtendedResultMapper extends DefaultResultMapper {
protected MappingContext<? extends ElasticsearchPersistentEntity<?>, ElasticsearchPersistentProperty> mappingContext;
public ExtendedResultMapper(MappingContext<? extends ElasticsearchPersistentEntity<?>, ElasticsearchPersistentProperty> mappingContext) {
super(mappingContext);
this.mappingContext = mappingContext;
}
#Override
public <T> T mapResult(GetResponse response, Class<T> clazz) {
T result = super.mapResult(response, clazz);
if (result != null) {
setPersistentEntityVersion(result, response.getVersion(), clazz);
}
return result;
}
#Override
public <T> LinkedList<T> mapResults(MultiGetResponse responses, Class<T> clazz) {
LinkedList<T> results = super.mapResults(responses, clazz);
if (results != null) {
for (int i = 0; i < results.size(); i++) {
setPersistentEntityVersion(results.get(i), responses.getResponses()[i].getResponse().getVersion(), clazz);
}
}
return results;
}
private <T> void setPersistentEntityVersion(T result, Long version, Class<T> clazz) {
if (mappingContext != null && clazz.isAnnotationPresent(Document.class)) {
PersistentProperty<ElasticsearchPersistentProperty> versionProperty = mappingContext.getPersistentEntity(clazz).getVersionProperty();
if (versionProperty != null && versionProperty.getType().isAssignableFrom(Long.class)) {
Method setter = versionProperty.getSetter();
if (setter != null) {
try {
setter.invoke(result, version);
} catch (Throwable t) {
t.printStackTrace();
}
}
}
}
}
}
You can tell Spring to use this version instead of the default mapper as follows:
#Autowired
private Client client;
#Bean
public ElasticsearchTemplate elasticsearchTemplate() {
MappingElasticsearchConverter converter = new MappingElasticsearchConverter(new SimpleElasticsearchMappingContext());
ExtendedResultMapper mapper = new ExtendedResultMapper(converter.getMappingContext());
return new ElasticsearchTemplate(client, converter, mapper);
}
Note that the version is only populated for Get or Multi-Get requests. Search results do not include version information.
You could also use this same approach to extract other information from the GetResponse objects.
Using this code, if you get a document and then try to save it back, it will fail unless you increment the version.
I'm trying to follow the new Cineasts app with SDN 4.0.0.M1 and SpringBoot to learn Spring and Neo4j but I have an error when I try to access the movie url with
curl http://localhost:8080/movies
MappingException: Error mapping GraphModel to instance
I implemented the minimum to get something working so the code is simple but I probably forgot something

I started Neo4j and added one record with Neo4j browser
CREATE (m:Movie {id:1, name:'The Matrix'}) return m
when I go to localhost:8080 I can see the json response
{
"_links" : {
"movies" : {
"href" : "http://localhost:8080/movies"
},
"profile" : {
"href" : "http://localhost:8080/alps"
}
}
but it fails to display the movies or http://localhost:8080/movies/1 record I just created. Any idea to fix this or get a more relevant message?
Thanks!
The problem could be the fact that your entity definition does not match that of the node you've created.
The Movie class defines a property id of data type String, and a property title of type String.
The Cypher you used however
CREATE (m:Movie {id:1, name:'The Matrix'}) return m
creates a node with a number id instead of a String id and a name property instead of a title property.
Changing the above to
CREATE (m:Movie {id:'1', title:'The Matrix'}) return m
should fix it.
I'm using grails 2.3.4 and I have a domain class that embeds an object. The embedded object has a property called 'version' and it seems that this is conflicting with the 'version'-field automatically added to the database-table by GORM. The result is that the 'version'-field belonging to my embedded object isn't created in the database and as a consequence my application doesn't work properly.
My code looks like this:
class Thing {
String someText
EmbeddedThing embeddedThing
Date someDate
static embedded = ['embeddedThing']
static constraints = {
embeddedThing(unique: true)
}
}
class EmbeddedThing {
String textOfSomeSort
String version
String textOfSomeOtherSort
}
You might think that a quick fix is to rename the 'version'-property of the embedded object but the class belongs to an included sub-project (i.e. a JAR-file) that I'm not allowed to touch since other projects use it. So the solution needs to be done completely within my domain class, or at least in a manner that doesn't change the class of the embedded object.
version is a special column name, you should rename your version field within your EmbeddedThin class
I actually found a solution to this problem by using a Hibernate UserType to represent the EmbeddedThing-class.
My code now looks like this and works perfectly:
Thing.groovy:
import EmbeddedThingUserType
class Thing {
String someText
EmbeddedThing embeddedThing
Date someDate
static embedded = ['embeddedThing']
static mapping = {
version false
embeddedThing type: EmbeddedThingUserType, {
column name: "embedded_thing_text"
column name: "embedded_thing_version"
column name: "embedded_thing_other_text"
}
}
static constraints = {
embeddedThing(unique: true)
}
}
EmbeddedThing.groovy:
class EmbeddedThing {
String textOfSomeSort
String version
String textOfSomeOtherSort
}
EmbeddedThingUserType.groovy:
class EmbeddedThingUserType implements UserType {
int[] sqlTypes() {
return [StringType.INSTANCE.sqlType(),
StringType.INSTANCE.sqlType(),
StringType.INSTANCE.sqlType()]
}
Class returnedClass() {
return EmbeddedThing
}
public Object nullSafeGet(ResultSet resultSet, String[] names, Object owner)
throws HibernateException, SQLException {
if (resultSet && names) {
return new EmbeddedThing(
textOfSomeSort: resultSet?.getString(names[0] ?: '_missing_textOfSomeSort_'),
version: resultSet?.getString(names[1] ?: '_missing_version_'),
textOfSomeOtherSort: resultSet?.getString(names[2] ?: '_missing_textOfSomeOtherSort_'))
} else {
return null
}
}
public void nullSafeSet(PreparedStatement preparedStatement, Object value, int index)
throws HibernateException, SQLException {
if (value != null) {
preparedStatement.setString(index, value?.textOfSomeSort)
preparedStatement.setString(index + 1, value?.version)
preparedStatement.setString(index + 2, value?.textOfSomeOtherSort)
} else {
preparedStatement.setString(index, '_missing_textOfSomeSort_')
preparedStatement.setString(index + 1, '_missing_version_')
preparedStatement.setString(index + 2, '_missing_textOfSomeOtherSort_')
}
}
