I have tried to follow this documentation in the most precise way I could:
https://beam.apache.org/documentation/sdks/javadoc/2.0.0/org/apache/beam/sdk/io/xml/XmlIO.html
Please find below my codes :
public static void main(String args[])
{
DataflowPipelineOptions options=PipelineOptionsFactory.as(DataflowPipelineOptions.class);
options.setTempLocation("gs://balajee_test/stagging");
options.setProject("test-1-130106");
Pipeline p=Pipeline.create(options);
PCollection<XMLFormatter> record= p.apply(XmlIO.<XMLFormatter>read()
.from("gs://balajee_test/sample_3.xml")
.withRootElement("book")
.withRecordElement("author")
.withRecordElement("title")
.withRecordElement("genre")
.withRecordElement("price")
.withRecordElement("description")
.withRecordClass(XMLFormatter.class)
);
record.apply(ParDo.of(new DoFn<XMLFormatter,String>(){
#ProcessElement
public void processElement(ProcessContext c)
{
System.out.println(c.element().getAuthor());
}
}));
p.run();
}
I'm getting 'null' value for every XML component. Could you please review my code and suggest me the corrective course of action required?
package com.bitwise.cloud;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;
import javax.xml.bind.annotation.XmlType;
#XmlRootElement(name = "book")
#XmlType(propOrder = {"author", "title","genre","price","description"})
public class XMLFormatter {
private String author;
private String title;
private String genre;
private String price;
private String description;
public XMLFormatter() { }
public XMLFormatter(String author, String title,String genre,String price,String description) {
this.author = author;
this.title = title;
this.genre = genre;
this.price = price;
this.description = description;
}
#XmlElement
public void setAuthor(String author) {
this.author = author;
}
public String getAuthor() {
return author;
}
#XmlElement
public void setTitle(String title) {
this.title = title;
}
public String getTitle() {
return title;
}
#XmlElement
public void setGenre(String genre) {
this.genre = genre;
}
public String getGenre() {
return genre;
}
#XmlElement
public void setPrice(String price) {
this.price = price;
}
public String getPrice() {
return price;
}
#XmlElement
public void setDescription(String description) {
this.description = description;
}
public String getDescription() {
return description;
}
}
XmlIO.Read PTransform doesn't support providing multiple record elements (author, title, genre, etc). You have to provide a single root element and a record element and your XML document has to contain records that have the same record element. See the example given in the following location.

Would like to know how to hide a model property in Swagger on POST. I have tried both Swagger-springmvc (0.9.3) and Springfox (supports swagger spec 2.0) to no avail.
Problem being I would like to see this in the GET requests through Swagger. But not POST requests, since id is auto-assigned, I would like to hide it just for the POST request.
public class RestModel {
private int id;
#JsonProperty
private String name;
#JsonProperty
public int getId() {
return 0;
}
#JsonIgnore
public void setId(int customerId) {
this.customerId = customerId;
}
public int getName() {
return "abc";
}
public void setName(String name) {
this.name = name;
}
}
So on GET, I should see:
{
"id": 0,
"name" : "abc"
}
And on POST, I should see just:
{
"name"
}
Tried adding: #ApiModelProperty(readonly=true). But that didn't help.
I have solved this with simply extending the Object that I want to hide a property of when using as request parameter.
Example:
I have the object Person.java:
import com.fasterxml.jackson.annotation.JsonFormat;
import com.fasterxml.jackson.annotation.JsonIgnore;
import com.fasterxml.jackson.annotation.JsonProperty;
import com.fasterxml.jackson.annotation.JsonView;
import org.joda.time.DateTime;
import org.joda.time.Years;
import java.util.Date;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import io.swagger.annotations.ApiModelProperty;
/**
* Simple Person pojo
*/
#Entity
public class Person {
#GeneratedValue(strategy = GenerationType.AUTO)
#Id
private Long dbId;
private String name;
private Long id;
#JsonFormat(pattern="yyyy-MM-dd")
private Date birthDate;
private String gender;
public Person() {
}
public Person(long dbId) {
this.dbId = dbId;
}
public Person(Long id, String name, Date birthDate, String gender) {
this.id = id;
this.name = name;
this.birthDate = birthDate;
this.gender = gender;
}
public Long getDbId() {
return dbId;
}
public String getName() {
return name;
}
public Date getBirthDate() {
return birthDate;
}
public String getGender() {
return gender;
}
public Integer getAge() {
return Years.yearsBetween(new DateTime(birthDate), new DateTime()).getYears();
}
public void setDbId(Long dbId) {
this.dbId = dbId;
}
public void setName(String name) {
this.name = name;
}
public void setBirthDate(Date birthDate) {
this.birthDate = birthDate;
}
public void setGender(String gender) {
this.gender = gender;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
}
I have simply created another class: PersonRequest.java:
import com.fasterxml.jackson.annotation.JsonIgnore;
public class PersonRequest extends Person {
#Override
#JsonIgnore
public void setDbId(Long dbId) {
super.setDbId(dbId);
}
}
RequestMapping looks simply like:
#RequestMapping(value = "/KVFirstCare/application", method = RequestMethod.POST)
public ApplicationResult application(#RequestBody List<PersonRequest> persons,
HttpServletResponse response) {
}
Works like charm :)
Unfortunately having different request and response models is not supported currently in springfox. The current thought is that we might support this feature using #JsonView in the future.
I am having a hard time figuring this out. I have implemented Repository and Unit of Work patterns as a data access abstraction for my database. I am using Dependency Injection to inject them into the controller. The problem is when the controller is disposed, it disposes the repository, but then when I refresh the page, DbContext object inside repository is null (it shouldn't be, I think). The implementation of classes is shown below.
This is the database Repository class:
public class ConferenceCrawlyDbRepository : IConferenceCrawlyDbRepository
{
private ConferenceCrawlyDbContext _context = null;
private static ConferenceCrawlyDbRepository _instance = null;
public IRepository<AcademicDegree> AcademicDegrees { get; private set; }
public IRepository<Conference> Conferences { get; private set; }
public IRepository<ConferenceComment> ConferenceComments { get; private set; }
public IRepository<ConferenceRating> ConferenceRatings { get; private set; }
public IRepository<ConnectionConferenceRecommendation> ConnectionConferenceRecommendation { get; private set; }
public IRepository<Country> Countries { get; private set; }
public IRepository<ImportantDate> ImportantDates { get; private set; }
public IRepository<Topic> Topics { get; private set; }
public IRepository<UserProfile> UserProfiles { get; private set; }
public IRepository<UserProfileSettings> UserProfileSettings { get; private set; }
public IRepository<UsersConnection> UserConnections { get; private set; }
public IRepository<Venue> Venues { get; private set; }
private ConferenceCrawlyDbRepository(ConferenceCrawlyDbContext context)
{
_context = context;
AcademicDegrees = new Repository<AcademicDegree>(context);
Conferences = new Repository<Conference>(context);
ConferenceComments = new Repository<ConferenceComment>(context);
ConferenceRatings = new Repository<ConferenceRating>(context);
ConnectionConferenceRecommendation = new Repository<ConnectionConferenceRecommendation>(context);
Countries = new Repository<Country>(context);
ImportantDates = new Repository<ImportantDate>(context);
Topics = new Repository<Topic>(context);
UserProfiles = new Repository<UserProfile>(context);
UserProfileSettings = new Repository<UserProfileSettings>(context);
UserConnections = new Repository<UsersConnection>(context);
Venues = new Repository<Venue>(context);
}
public static ConferenceCrawlyDbRepository Instance
{
get
{
if (_instance == null)
_instance = new ConferenceCrawlyDbRepository(new ConferenceCrawlyDbContext());
return _instance;
}
}
public bool CommitChanges()
{
try
{
return _context.SaveChanges() > 0;
}
catch
{
// TODO: Add logging
return false;
}
}
public void Dispose()
{
if (_context != null)
_context.Dispose();
}
And this is the generic repository class:
public class Repository<TEntity> : IRepository<TEntity> where TEntity : class
{
private ConferenceCrawlyDbContext _context = null;
private DbSet<TEntity> _dbSet = null;
public Repository(ConferenceCrawlyDbContext context)
{
_context = context;
_dbSet = context.Set<TEntity>();
}
public DbSet<TEntity> DbSet
{
get
{
return _dbSet;
}
}
public bool Add(TEntity entity)
{
try
{
DbSet.Add(entity);
return true;
}
catch (Exception ex)
{
// TODO: Add logging
return false;
}
}
public bool Update(TEntity entity)
{
try
{
var entry = _context.Entry<TEntity>(entity);
DbSet.Attach(entity);
entry.State = EntityState.Modified;
return true;
}
catch(Exception ex)
{
// TODO: Add logging
return false;
}
}
public bool Remove(TEntity entity)
{
try
{
DbSet.Remove(entity);
return true;
}
catch (Exception ex)
{
// TODO: Add logging
return false;
}
}
public IQueryable<TEntity> GetAll()
{
return DbSet;
}
public IQueryable<TEntity> Find(Expression<Func<TEntity, bool>> predicate)
{
return DbSet.Where(predicate);
}
public TEntity FindById(params object[] keys)
{
return DbSet.Find(keys);
}
public bool Contains(Expression<Func<TEntity, bool>> predicate)
{
return _dbSet.Any(predicate);
}
public bool CommitChanges()
{
try
{
return _context.SaveChanges() > 0;
}
catch
{
// TODO: Add logging
return false;
}
}
public void Dispose()
{
if (_context != null)
_context.Dispose();
}
}
Here is my custom controller factory for dependency injection:
public class CustomControllerFactory : DefaultControllerFactory
{
protected override IController GetControllerInstance(RequestContext requestContext, Type controllerType)
{
if (controllerType != null)
{
if (controllerType.GetConstructor(new Type[] { typeof(IConferenceCrawlyDbRepository) }) != null)
return Activator.CreateInstance(controllerType, new object[] { ConferenceCrawlyDbRepository.Instance }) as Controller;
else if (controllerType.GetConstructor(new Type[] { typeof(IConferenceCrawlyDbRepository), typeof(IMailService) }) != null)
return Activator.CreateInstance(controllerType, new object[] { ConferenceCrawlyDbRepository.Instance,
#if DEBUG
MockMailService.Instance
#else
MailService.Instance
#endif
}) as Controller;
}
return base.GetControllerInstance(requestContext, controllerType);
}
And finally, controller with its action:
public class HomeController : Controller
{
private IConferenceCrawlyDbRepository _dbRepository;
private IMailService _mailService;
public HomeController(IConferenceCrawlyDbRepository dbRepository, IMailService mailService)
{
_dbRepository = dbRepository;
_mailService = mailService;
}
//
// GET: /
public ActionResult Index()
{
var countries = _dbRepository.Countries.GetAll().ToList();
return View(countries);
}
//
// GET: /Home/About
public ActionResult About()
{
return View();
}
//
// GET: /Home/Contact
public ActionResult Contact()
{
return View(new Contact());
}
//
// POST: /Home/Contact
[HttpPost]
[ValidateAntiForgeryToken]
public async Task<ActionResult> Contact(Contact contact)
{
if (ModelState.IsValid)
{
if (await _mailService.SendMail(contact.Email, contact.Title,
String.Format("{1}{0}{2}", Environment.NewLine, contact.Message, String.IsNullOrEmpty(contact.Name) ? "Anonimous" : contact.Name)))
{
ViewBag.SuccessMessage = "Comment has been successfully sent.";
return View(new Contact());
}
else
ViewBag.ErrorMessage = "Couldn't send your email. Please try again later";
}
return View(contact);
}
protected override void Dispose(bool disposing)
{
if (_dbRepository != null)
_dbRepository.Dispose();
base.Dispose(disposing);
}
}
The Exception is thrown inside index action when I call the repository, but only after the first time accessing this controller and it says that DbContext object inside repository. I am obviously doing something wrong, but I can't figure it out.
I figure it out after long staring and debugging of code. It's so simple, because I'm disposing context inside ConferenceCrawlyDbRepository I should also set _instance object which is using it to null, and then it will be recreated along with DbContext object. I fell so stupid right now...
The problem is since my POJO/Domain classes are in java (obvious actually but just to make it clear) the sub-object that i use does'nt show up properly in the form when I click on available controllers: Eg: Patient has address -->> address is a sub-object in patient:
The address field shows a blank dropdown. How do i resolve this?
I am using def scaffold= in the controller.

As far as I know, Grails only supports GORM-mappings (http://grails.org/doc/latest/guide/single.html#ormdsl) and hibernate mappings (http://grails.org/doc/latest/guide/single.html#hibernate)
I don't think the mappings you provide are valid for scaffolding.
