Question

При отправке запроса GET на мой UserResource я получаю следующую ошибку.

1002 * Hibernate: выберите user0_.user_id в user_id1_1_0_, user0_.address как address2_1_0_, user0_.birthdate как birthdat3_1_0_, user0_.email как email4_1_0_, user0_.flag как flag5_1_0_, user0_.password как password6_1_0_, user0_.role как role7_1_0_, user0_.username как username8_1_0_ от пользователей user0_, где user0_.user_id =?07 июня 2019 г., 17:45:20 org.glassfish.jersey.message.internal.WriterInterceptorExecutor $ TerminalWriterInterceptor aroundWriteTo SEVERE: MessageBodyWriter не найден для типа носителя = text / plain, type = class com.ikubinfo.project.model.UserModel,genericType = class com.ikubinfo.project.model.UserModel.

На самом деле оператор Hibernate отправляется в базу данных, но не возвращает мне объект.

Я использую JsonWebTokens для выполненияаутентификация, JPA

Вот мой класс UserResource.

import javax.ws.rs.Consumes;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;

import com.ikubinfo.project.service.UserService;
import com.ikubinfo.project.util.Paths;

@Path(Paths.USERS)
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public class UserResource {
    private UserService userService;

    public UserResource() {
        this.userService= new UserService();
    }

    @GET
    @Path("/{id}")
    public Response getUserById(@PathParam("id") final int id) {
        return Response.ok((userService.getUser(id))).build();
    }
}

Вот UserModel, который преобразует сущность User в модель.

import java.util.Date;
public class UserModel {
    private int id;
    private String username;
    private String password;
    private String role;
    private Date birthdate;
    private String email;
    private String address;
    private boolean flag;

    public UserModel() {

    }

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public String getRole() {
        return role;
    }

    public void setRole(String role) {
        this.role = role;
    }

    public Date getBirthdate() {
        return birthdate;
    }

    public void setBirthdate(Date birthdate) {
        this.birthdate = birthdate;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

    public boolean isFlag() {
        return flag;
    }

    public void setFlag(boolean flag) {
        this.flag = flag;
    }

}

Класс UserService

import com.ikubinfo.project.converter.UserConverter;
import com.ikubinfo.project.model.UserModel;
import com.ikubinfo.project.repository.UserRepository;

public class UserService {
    private UserRepository userRepository;
    private UserConverter userConverter;

    public UserService() {
        userRepository = new UserRepository();
        userConverter = new UserConverter();
    }

    public UserModel getUser(int id) {
        return userConverter.toModel(userRepository.getUser(id));
    }

    public UserModel getUserByUsername(String username) {
        return userConverter.toModel(userRepository.getUserByUsername(username));
    }
}

Я ожидаю, что объект будет возвращен почтальоном.
