Inject user entity with EJB

I use JAAS authentication in my application. Think think that I have User Entity class like this:

@Entity
public class User {
    @Id
    public Long id;

    public String name;

    ...

and a rest API like this:

@Stateless
@LocalBean
@Path("/users")
public class Users {

    // INJECT USER OBJECT HERE
    @Inject
    private User user;

    @Path("/me")
    @Produces({ MediaType.APPLICATION_JSON })
    @GET
    public User getUser() {
        return user;
    }
    ...

Is there anyway I create a @Produces method to generate User entity object from @SessionContext.getCallerPrincipal() and EntityManager and Inject it directly into the all rest apis that I want?

When you saved the id of user as principle name following way should work. You need a qualifier and a producer method. A good way is to create another class to get the user entity.

public class Resource {
  @Inject
  private EntityManager em;

  @Resource
  private SessionContext ctx;

  @Produces
  @Sessionscoped
  @Running // the qualifier
  public User getUser() {
    User user = em.find(User.class, ctx.getCallerPrincipal().getName());
    return user;
  }
}

In your Users class, you have to annotate the injected user with the qualifier to. Otherwise the User entity of the producer method can not be alloacted to the injection.

@Inject
@Running
private User user;
