我的项目Spring Boot在创建Bean中出现的问题

Question

我的UserController

@RestController
@RequestMapping(path= "/api")
@RequiredArgcContructor
public class UserController {

    
    private final UserService userService;

    @PostMapping
    public String create(@RequestBody UserDTO userDto){
        return  userService.save(userDto);
    }

}

我的用户服务

@Service
@RequiredArgsConstructor
public class UserService {

 
    private  UserManager userManager;
    private  Mapper<UserDTO, UserEntity> userDTOUserMapper;

    public String save(UserDTO userDto) {
        return userManager.signUp(userDTOUserMapper.map(userDto));
    }

}

问题出在哪里？我不明白

Answer 1

好的，看起来错误是：

.MappingException: The get-method for property 'enabled' in type com.userlogintask.userlogintask.model.UserEntity is not a valid Java Bean property. at

这就是为什么映射器不能按需要创建的原因，这又会导致服务的BeanInitializationException。

查看您的实体，您使用:boolean表示enabled属性，但是getter返回boolean（不是包装类，而是一个真正的原语）。试着改变它，看看会发生什么。
