创建名称为'userController'的bean时出错：通过字段'userRepository'表示的不满意依赖性；

标签： spring annotations h2

我正在尝试在我的JPA存储库中针对一个简单的项目进行自定义查询，该项目涉及spring和angular并出现一些我无法弄清的错误。我需要的只是一个基于用户名的登录系统ID。

我的仓库

package systemphones.backend.repository;

imports...

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

    @Query("SELECT ID FROM USER WHERE USER_NAME = ?1")
    Long getUser(String userName);


}

我的控制器

package systemphones.backend.controller;

imports...

import java.util.List;


@Controller
public class UserController {

    @Autowired
    UserRepository userRepository;

    .
    .
    .

    @GetMapping(path = "/test")
    public Long getUser(@RequestParam String userName) {


        return userRepository.getUser(userName);
    }

    .
    .
    .   
}

错误：

很抱歉，很长的帖子。希望它足够干净，任何人都可以帮助我 预先感谢您愿意提供帮助的人

2 个答案:

答案 0 :(得分：1)

该错误消息表明JPA查询的语法存在问题。 尝试以下调整：

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

    @Query("SELECT ID FROM USER WHERE USER_NAME = userName")
    Long getUser(@Param("userName") String userName);

}

希望这会有所帮助。

答案 1 :(得分：1)

尝试替换此：

@Query("SELECT ID FROM USER WHERE USER_NAME = ?1")

与此：

@Query("SELECT ID FROM USER WHERE USER_NAME = ?1", nativeQuery=true)
