我是 Spring Boot 和MapStruct工具的新手。
早些时候,一个项目(由其他团队使用这些技术编写)没有启动。然后,我在 Mapper 抽象类中做了一些更改,但现在映射器对象在应用程序启动时变为 null。
映射器抽象类:
@Mapper(componentModel = "spring")
public abstract class UserAndEmployeeMapper {
public UserAndEmployeeMapper INSTANCE = Mappers.getMapper( UserAndEmployeeMapper.class );
@Mapping(source = "username", target = "name")
@Mapping(source = "ssn", target = "ssn", defaultValue = "xxxxxx" )
@Mapping(target = "salary", constant = "34.67")
@Mapping(target = "dob", dateFormat = "dd/MM/yyyy", constant = "10/12/2002")
public abstract Employee mapToEmployee(User user);
public abstract List<Employee> mapToEmployee(List<User> users);
@Mapping(source = "name", target = "username")
public abstract User mapToUser(Employee employee);
public abstract List<User> mapToUser(List<Employee> employees);
}
LoginServiceImpl 类
@Service("loginService")
public class LoginServiceImpl implements LoginService{
private static final AtomicLong counter = new AtomicLong();
@Autowired
private EmployeeDao employeeDao;
private UserAndEmployeeMapper userAndEmployeeMapper;
...
}

在 LoginServiceImpl 中添加 @Autowired 后,应用程序未启动并显示以下错误日志
***************************
APPLICATION FAILED TO START
***************************
Description:
Field userAndEmployeeMapper in org.service.impl.LoginServiceImpl required a bean of type 'org.mapper.UserAndEmployeeMapper' that could not be found.
Action:
Consider defining a bean of type 'org.mapper.UserAndEmployeeMapper' in your configuration.
有什么建议么 ?
