How to retrieve all data of the current User in controller? - spring

Question

I need take all data of the current user which is logged in and send it in JSON format into the route "/home". I was searching how to do it, but nothing.. I found that i can take only username and authorities there. Can someone help me to handle it? Thanks all.
There is my AuthController.java
// Getting all user data
#RequestMapping(value = "/home", method = RequestMethod.GET)
public String getUsersDataById(Principal principal) {
return principal.getName();
}
There is my UserRepository
import com.example.demo.Models.Users;
import org.springframework.data.jpa.repository.JpaRepository;
import java.util.Optional;
public interface UserRepository extends JpaRepository<Users, Integer> {
Optional<Users> findByUsername(String username);
}
There are my services:
MyUserDetails.java
public class MyUserDetails implements UserDetails {
private String username;
private String password;
private String firstname;
private String lastname;
private String email;
private String last_login_date;
private String registration_date;
private String last_login_ip;
private Integer balance;
private Integer status;
private String brith_date;
private List<GrantedAuthority> authorities;
private boolean active;
public MyUserDetails(Users user) {
this.username = user.getUsername();
this.password = user.getPassword();
this.authorities = Arrays.stream(user.getRoles().split(","))
.map(SimpleGrantedAuthority::new)
.collect(Collectors.toList());
this.active = user.isActive();
}
public MyUserDetails(String username, String firstname, String lastname, String email, String last_login_date, String registration_date, String last_login_ip, Integer balance, Integer status, String brith_date) {
this.username = username;
this.firstname = firstname;
this.lastname = lastname;
this.email = email;
this.last_login_date = last_login_date;
this.registration_date = registration_date;
this.last_login_ip = last_login_ip;
this.balance = balance;
this.status = status;
this.brith_date = brith_date;
}
public MyUserDetails() {
}
// and Override methods by default..
MyUserDetailsService
#Service
public class MyUserDetailsService implements UserDetailsService {
#Autowired
private UserRepository userRepository;
#Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
Optional<Users> user = userRepository.findByUsername(username);
user.orElseThrow(() -> new UsernameNotFoundException("Not found: " + username));
return user.map(MyUserDetails::new).get();
}
}
There is Users.java with columns from table and geters and setters without constructor
#Entity
#Table(name = "users")
public class Users {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private Integer id;
private String username;
...
/// etc..
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
...
// etc..

Annotate your method with #AuthenticationPrincipal and use UserDetails.
#RequestMapping(value = "/home", method = RequestMethod.GET)
public Userdetails getUsersDataById(#AuthenticationPrincipal UserDetails userDetails) {
return userDetails;
}
