My entity class (usually)
@Entity
public class User {
private String firstname;
private String lastname;
private String username;
private String email;
private String birthdate;
// ...
}User resource with some basics information that all users can see
public class BasicUserResource {
private String firstname;
private String username;
// ...
}User resource with full information. Only Admin can see
public class FullUserResource {
private String firstname;
private String lastname;
private String username;
private String email;
private String birthdate;
// ...
}Assembler to convert the domain class (User) into a resource
public class UserAssembler extends GenericResourceAssembler<UserDomain> {
public UserAssembler() {
super(UserDomain.class);
}
}A rest controller exemplo that converts the User domain to a specific resource
@RestController
@RequestMapping(value = "/api/v1", produces = MediaType.APPLICATION_JSON_VALUE)
class UserController {
private UserAssembler assembler = new UserAssember();
/** Will return the basic user information. */
@GetMapping(path = "/users/{username}")
public ResponseEntity getBasicUser(@PathVariable String username) {
User domain = this.service.findUserByUsername(username);
BasicUserResource resource = this.assembler.fromDomain(domain, BasicUserResource.class);
return ResponseEntity.ok(resource);
}
/** Will return all the user information (Admin only). */
@GetMapping(path = "/admin/users/{username}")
public ResponseEntity getBasicUser(@PathVariable String username) {
User domain = this.service.findUserByUsername(username);
FullUserResource resource = this.assembler.fromDomain(domain, FullUserResource.class);
return ResponseEntity.ok(resource);
}
}
