我在测试我的简单 spring mvc 服务时出错

Question

我使用 spring boot 和 spring mvc 创建了一个新服务。

UserEntity.class：

@Entity
@Table(name = "users")
public class UserEntity {

    private long id;
    private String username;
    private String password;
    private boolean active;
    private boolean login;

    public UserEntity(UserDto dto) {
        this.id = dto.getId();
        this.username = dto.getUsername();
        this.password = dto.getPassword();
        this.active = dto.isActive();
    }

    // getters&setters...
}

UserDto.class：

public class UserDto {

    private long id;
    private String username;
    private String password;
    private boolean active;

    public UserDto(long id, String username, String password, boolean active) {
        this.id = id;
        this.username = username;
        this.password = password;
        this.active = active;
    }
    // getters&setters...
}

用户存储库：

@Repository
public interface UserRepository extends JpaRepository<UserEntity, Long> {

}

UserServiceImpl.class：（和 UserService 接口）

@Service
@Transactional
public class UserServiceImpl implements UserService {

    private final UserRepository repo;

    @Autowired
    public UserServiceImpl(UserRepository repo) {
        this.repo = repo;
    }

    @Override
    public boolean saveUser(UserDto dto) {
        UserEntity user = new UserEntity(dto);
        repo.save(user);
        return true;
    }
}

用户控制器类：

@RestController
public class UserController {

    private final UserService service;

    @Autowired
    public UserController(UserService service) {
        this.service = service;
    }

    @RequestMapping(value = "/users", method = RequestMethod.POST)
    public void createUser(@RequestBody UserDto userDto) {
        service.saveUser(userDto);
    }

}

Application.class：

@EnableAutoConfiguration
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class,args);
    }

}

我的 Spring Boot 项目正确启动。但是当我使用 IntelliJ Test Restful Web Service Tool 测试我的服务时，我遇到了一个错误：

回复：

 {"timestamp":1464066878392,"status":405,"error":"Method Not Allowed","exception":"org.springframework.web.HttpRequestMethodNotSupportedException","message":"Request method 'POST' not supported","path":"/users"}

有什么问题？

Answer 1

我的建议是从 UserController 和 UserServiceImpl 类中删除构造函数，不需要它们。然后，将 @Autowired 注释分配给声明。另外，我认为您不需要将它们设为final。

UserServiceImpl.class：

@Service
@Transactional
public class UserServiceImpl implements UserService {

    @Autowired
    private UserRepository repo;

    @Override
    public boolean saveUser(UserDto dto) {
        UserEntity user = new UserEntity(dto);
        repo.save(user);
        return true;
    }
}

用户控制器类：

@RestController
public class UserController {

    @Autowired    
    private UserService service;

    public UserController(UserService service) {
        this.service = service;
    }

    @RequestMapping(value = "/users", method = RequestMethod.POST)
    public void createUser(@RequestBody UserDto userDto) {
        service.saveUser(userDto);
    }
}
