I need to customize message so I tried to modify the LoginController by simply overriding the grails .plugin.springsecurity.LoginController
I have thrown AccountNotApprovedException from my customizedAuthenticationProvider.
Can someone suggest me what I am missing?
class AccountNotApprovedException extends AuthenticationException{
public AccountNotApprovedException(String message, Throwable t) {
super(message, t)
}
public AccountNotApprovedException(String message) {
super(message)
}
/** #deprecated */
#Deprecated
public AccountNotApprovedException(String message, Object extraInformation) {
super(message, extraInformation)
}
}
I override the loginController:-
class LoginController extends grails.plugin.springsecurity.LoginController {
def authenticationTrustResolver
/**
* Dependency injection for the springSecurityService.
*/
def springSecurityService
def authfail() {
//my customized code
}
}
And when springSecurity runs then it didn't call my overridden authFail()

when an error occurs inside the application, the user sees the following message:
Is it possible to override it?
I aaded the following:
public class CustomErrorHandler implements ErrorHandler {
private static final Logger logger = LoggerFactory.getLogger(CustomErrorHandler.class);
#Override
public void error(ErrorEvent errorEvent) {
logger.error("Something wrong happened", errorEvent.getThrowable());
Notification.show("An internal error has occurred. Please contact support.");
if (UI.getCurrent() != null) {
UI.getCurrent().access(() -> {
Notification.show("An internal error has occurred. Please contact support.");
});
}
}
}
#Component
public class ServiceListener implements VaadinServiceInitListener {
private static final Logger logger = LoggerFactory.getLogger(LanguageReceiver.class);
#Override
public void serviceInit(ServiceInitEvent event) {
event.getSource().addSessionInitListener(
initEvent -> {
logger.info("A new Session has been initialized!");
VaadinSession.getCurrent().setErrorHandler(new CustomErrorHandler());
});
event.getSource().addUIInitListener(
initEvent -> logger.info("A new UI has been initialized!"));
}
}
#ParentLayout(MainLayout.class)
#AnonymousAllowed
public class ExceptionHandler extends VerticalLayout implements HasErrorParameter<Exception> {
static final Logger logger = LoggerFactory.getLogger(ExceptionHandler.class);
#Override
public int setErrorParameter(BeforeEnterEvent event, ErrorParameter<Exception> parameter) {
logger.error("Error", parameter.getException());
Label label = new Label(parameter.getException().getMessage());
add(label);
return HttpServletResponse.SC_NOT_FOUND;
}
}
but still unable to override the mentioned error on the screenshot above. Please show how to do this.
Generally, you need to extend SystemMessages and override getInternalErrorMessage().
Then you can register it using:
YourSystemMessages sysMessages = new YourSystemMessages();
VaadinService.getCurrent().setSystemMessagesProvider(systemMessagesInfo -> sysMessages);
and if you want to reset it to the default one:
VaadinService.getCurrent().setSystemMessagesProvider(DefaultSystemMessagesProvider.get());
In a Spring Boot based application you can register it in any implementation of VaadinServiceInitListener such as:
#Component
public class CustomSystemMessagesInitializer implements VaadinServiceInitListener {
#Autowired
private YourSystemMessages sysMessages;
// You can provide your SystemMessages instance in any way that suits you.
#Override
public void serviceInit(ServiceInitEvent serviceInitEvent) {
serviceInitEvent.getSource()
.setSystemMessagesProvider(systemMessagesInfo -> sysMessages);
}
}
Note that serviceInitEvent.getSource() returns the VaadinService instance, so it can be used as the reference as an alternative to VaadinService.getCurrent.
I'm trying to understand Jersey 2 development and context-dependency injection.
I don't understand how to inject into a resource an object that needs initialization parameters in the constructor.
For example: I'd like to #Inject slf4j Logger, built using LoggerFactory.
My resource class is:
#Path("/myresource")
public class MyResource {
#Inject
private Logger log;
#GET
#Produces(MediaType.APPLICATION_JSON)
public Answer status() {
log.info("STATUS");
return new Answer(200, "Server up and running # "+ ZonedDateTime.now());
}
}
My Resource config is:
public class MyAppextends ResourceConfig {
public MyApp() {
register(new MyBinder());
packages(true, "my.packages");
}
}
public class MyBinder extends AbstractBinder {
#Override
protected void configure() {
bindFactory(MyLoggerFactory.class).to(org.slf4j.Logger.class);
}
}
Finally, the Factory is:
public class MyLoggerFactory implements Factory<Logger> {
#Override
public Logger provide() {
return LoggerFactory.getLogger(TYPE_FOR_LOGGING.class);
}
#Override
public void dispose(Logger logger) {
}
}
How can I specify TYPE_FOR_LOGGING as argument, in order to Inject the correctly initialized Logger in every resource I want?
Thanks
What you are looking for is called the InstantiationService. You can inject it into Factories to find out who is calling the factory inside of the provide method.
Below find a code sample from the hk2 tests that illustrate the use of the InstantiationService.
#Singleton
public class CorrelationFactory implements Factory<PerLookupServiceWithName> {
private final static PerLookupServiceWithName NULL_SERVICE = new PerLookupServiceWithName() {
#Override
public String getName() {
return null;
}
};
#Inject
private InstantiationService instantiationService;
/* (non-Javadoc)
* #see org.glassfish.hk2.api.Factory#provide()
*/
#Override #PerLookup
public PerLookupServiceWithName provide() {
InstantiationData data = instantiationService.getInstantiationData();
if (data == null) {
return NULL_SERVICE;
}
Injectee parent = data.getParentInjectee();
if (parent == null) {
return NULL_SERVICE;
}
Class<?> parentClass = parent.getInjecteeClass();
if (parentClass == null) {
return NULL_SERVICE;
}
Correlator correlator = parentClass.getAnnotation(Correlator.class);
if (correlator == null) {
return NULL_SERVICE;
}
final String fName = correlator.value();
return new PerLookupServiceWithName() {
#Override
public String getName() {
return fName;
}
};
}
/* (non-Javadoc)
* #see org.glassfish.hk2.api.Factory#dispose(java.lang.Object)
*/
#Override
public void dispose(PerLookupServiceWithName instance) {
// DO nothing
}
}
Hello i use spring boot 1.3.2 version. I have a custom argument resolver which's name is ActiveCustomerArgumentResolver. Everything is great, resolveArgument method works fine but i can't initialize my service component which is of my custom arg. resolver. Is there a problem with lifecycle process? Here is my code:
import org.springframework.beans.factory.annotation.Autowired;
//other import statements
public class ActiveCustomerArgumentResolver implements HandlerMethodArgumentResolver {
#Autowired
private CustomerService customerService;
#Override
public boolean supportsParameter(MethodParameter parameter) {
if (parameter.hasParameterAnnotation(ActiveCustomer.class) && parameter.getParameterType().equals(Customer.class))
return true;
else
return false;
}
#Override
public Object resolveArgument(MethodParameter parameter, ModelAndViewContainer mavContainer, NativeWebRequest webRequest, WebDataBinderFactory binderFactory) throws Exception {
Principal userPrincipal = webRequest.getUserPrincipal();
if (userPrincipal != null) {
Long customerId = Long.parseLong(userPrincipal.getName());
return customerService.getCustomerById(customerId).orNull(); //customerService is still NULL here, it keeps me getting NullPointerEx.
} else {
throw new IllegalArgumentException("No user principal is associated with the current request, yet parameter is annotated with #ActiveUser");
}
}
}
Let the Spring create the resolver for you by making it a Component:
#Component
public class ActiveCustomerArgumentResolver implements HandlerMethodArgumentResolver {...}
Then inject the resolver into your WebConfig instead of simply using the new, like following:
#EnableWebMvc
#Configuration
public class WebConfig extends WebMvcConfigurerAdapter {
#Autowired private ActiveCustomerArgumentResolver activeCustomerArgumentResolver;
#Override
public void addArgumentResolvers(List<HandlerMethodArgumentResolver> argumentResolvers) {
argumentResolvers.add(activeCustomerArgumentResolver);
}
}
This is how i've solved the problem, not a generic one but helps me a lot:
#Configuration
#EnableAutoConfiguration
#ComponentScan
public class Application extends WebMvcConfigurerAdapter {
private static final Logger logger = LoggerFactory.getLogger(Application.class);
#Override
public void addArgumentResolvers(List<HandlerMethodArgumentResolver> argumentResolvers) {
argumentResolvers.add(activeCustomerArgumentResolver());
}
#Bean
public ActiveCustomerArgumentResolver activeCustomerArgumentResolver() {
return new ActiveCustomerArgumentResolver();
}
}
I am using mail:1.0.1 plugin for mail sending
but while sending mail its gives me an error..
Source :-
def serviceMethod(EmailModel mailObj) {
PageRenderer groovyPageRenderer;
try{
sendMail {
to "abc#gmail.com"
subject mailObj.subject;
html groovyPageRenderer.render(template:"myMailTemplate", model: [mailObj: mailObj])
}
} catch (Throwable th) {
th.printStackTrace();
}
}
If you want to send the gsp page as email body then you can send it like:
def mailService
def serviceMethod(EmailModel mailObj) {
...
mailService.sendMail {
to email
subject "subject"
body(view: "/_template", model: [mailObj: mailObj])
}
...
}
EDIT...................................................................................
Just inject PageRenderer groovyPageRenderer globally, like
import grails.gsp.PageRenderer
class TestService {
PageRenderer groovyPageRenderer
def getText() {
String s = groovyPageRenderer.render(template: "../first/temp", model: [name: 'user1690588'])
println "Content = ${s}"
}
}
I think you are calling Service Class(.groovy) method from java class.
by using object of EmailService class.
So you cant get Object of PageRenderer class.
for this
Create SpringsUtil Class in src/java and define constant object of EmailSerevice. like this
public class SpringsUtil {
public static ApplicationContext getCtx() {
return getApplicationContext();
}
public static ApplicationContext getApplicationContext() {
return (ApplicationContext) ServletContextHolder.getServletContext().getAttribute(GrailsApplicationAttributes.APPLICATION_CONTEXT);
}
#SuppressWarnings("unchecked")
public static <T> T getBean(String beanName) {
return (T) getApplicationContext().getBean(beanName);
}
public static final String EMAIL_SERVICE = "emailService";
// public static final String INVENTORY_REORDER_SERVICE = "InventoryReorderService";
}
create object of Service class and call method
EmailService emailService = SpringsUtil.getBean(SpringsUtil.EMAIL_SERVICE);
I have a hard time understanding the injection mechanism of Jersey. The JAX-RS Specification (http://jsr311.java.net/nonav/releases/1.1/spec/spec3.html#x3-520005) states that injection via #Context is possible in Application subclasses, root resource classes and providers.
I now have a class that is instantiated at startup and has a method which is called on every request. Inside the method I need access to the current UriInfo object. The problem is, that this method is not called from my code. So I can't pass UriInfo directly to the method.
I actually want to do something like this:
public class MyClass implements ThirdPartyInterface {
// not possible because class is no Application subclass, root resource class or provider
#Context
private UriInfo uriInfo;
public void methodCallebByThirdPartyCode() {
Uri requestUri = uriInfo.getRequestUri();
// do something
}
}
I tried this. Obviously with no success:
public class MyClass implements ThirdPartyInterface {
private UriInfo uriInfo;
public MyClass(UriInfo uriInfo) {
this.uriInfo = uriInfo;
}
public void methodCallebByThirdPartyCode() {
Uri requestUri = uriInfo.getRequestUri();
// do something
}
}
#Provider
#Produces(MediaType.WILDCARD)
public class MyBodyWriter implements MessageBodyWriter<MyView> {
#Context
private UriInfo uriInfo;
private MyClass myClass;
private ThirdPartyClass thirdPartyClass;
public MyBodyWriter() {
// uriInfo is null at this time :(
myClass = new MyClass(uriInfo);
thirdPartyClass = new ThirdPartyClass();
thirdPartyClass.register(myClass);
}
public void writeTo(final MyView view, final Class<?> type, /* and so on */) throws IOException, WebApplicationException {
// execute() calls MyClass#methodCallebByThirdPartyCode()
thirdPartyClass.execute();
}
}
The only workaround I can think of is this. I don't think it's very clean:
public class MyClass implements ThirdPartyInterface {
private UriInfo uriInfo;
public void setUriInfo(final UriInfo uriInfo) {
this.uriInfo = uriInfo;
}
public void methodCallebByThirdPartyCode() {
Uri requestUri = uriInfo.getRequestUri();
// do something
}
}
#Provider
#Produces(MediaType.WILDCARD)
public class MyBodyWriter implements MessageBodyWriter<MyView> {
#Context
private UriInfo uriInfo;
private MyClass myClass;
private ThirdPartyClass thirdPartyClass;
public MyBodyWriter() {
myClass = new MyClass();
thirdPartyClass = new ThirdPartyClass();
thirdPartyClass.register(myClass);
}
public void writeTo(final MyView view, final Class<?> type, /* and so on */) throws IOException, WebApplicationException {
myClass.setUriInfo(uriInfo);
// execute() calls MyClass#methodCallebByThirdPartyCode()
thirdPartyClass.execute();
myClass.setUriInfo(null);
}
}
I hope there is a better solution, but maybe I'm completely on the wrong track.
Thanks!
Late answer, but a good question ... so lets go:
You can use a org.glassfish.hk2.api.Factory and javax.inject.Provider for injections. I don't know since which version this is available, so maybe you have to upgrade your jersery version. For the following samples i used jersey 2.12.
First you have to implement and register/bind a Factory for your MyClass:
MyClassFactory:
import javax.inject.Inject;
import javax.ws.rs.core.UriInfo;
import org.glassfish.hk2.api.Factory;
// ...
public class MyClassFactory implements Factory<MyClass> {
private final UriInfo uriInfo;
// we will bind MyClassFactory per lookup later, so
// the constructor will be called everytime we need the factory
// meaning, uriInfo is also per lookup
#Inject
public MyClassFactory(final UriInfo uriInfo) {
this.uriInfo = uriInfo;
}
#Override
public MyClass provide() {
return new MyClass(uriInfo)
}
#Override
public void dispose(UriInfo uriInfo) {
// ignore
}
}
Registration via ResourceConfig:
import org.glassfish.hk2.api.PerLookup;
import org.glassfish.hk2.utilities.binding.AbstractBinder;
import org.glassfish.jersey.server.ResourceConfig;
// ...
public class MyResourceConfig extends ResourceConfig {
public MyResourceConfig() {
register(new AbstractBinder() {
#Override
protected void configure() {
bindFactory(MyClassFactory.class).to(MyClass.class).in(PerLookup.class);
// ... bind additional factories here
}
});
// ...
}
}
Now you are able to inject MyClass per lookup to providers, resources etc.
But Attention: Afaig there are two approaches and only one will work as eventually aspected for providers ...
import javax.inject.Inject;
import javax.ws.rs.Produces;
import javax.ws.rs.ext.MessageBodyWriter;
import javax.ws.rs.ext.Provider;
// ...
#Provider
#Produces("application/foo-bar")
public class MyBodyWriter implements MessageBodyWriter<MyView> {
// first approache - don't do it!
// will only injected once, cause MyBodyWriter is only instantiated once
#Inject
private MyClass myClass;
// second approache - works fine!
private final javax.inject.Provider<MyClass> provider;
// MyBodyWriter instantiate once
// get an inject provider here
#Inject
public MyBodyWriter(javax.inject.Provider<MyClass> myClassProvider) {
this.provider = myClassProvider;
}
#Override
public boolean isWriteable(Class<?> t, Type g, Annotation[] a, MediaType m) {
return t == MyView.class;
}
#Override
public long getSize(MyView t, Class<?> c, Type g, Annotation[] a, MediaType m) {
// deprecated by JAX-RS 2.0 and ignored by Jersey runtime
return 0;
}
#Override
public void writeTo(MyView v, Class<?> c, Type t, Annotation[] a, MediaType m, MultivaluedMap<String, Object> s, OutputStream o) throws IOException, WebApplicationException {
// attention: its not per lookup !!!
MyClass myClassDirectInjected = myClass;
System.out.println(myClassDirectInjected); // same instance everytime
// but this is ;)
MyClass myClassFromProvider = provider.get();
System.out.println(myClassFromProvider); // it's a new instance everytime
// ...
}
}
Hope this was somehow helpfull.
