昨天完成了任务，今天早上打开程序的时候，突然报错，通过看日志是，autowire注入失败——Could not autowire field，经过排查，原来是Service 成忘记注入@Service了，不该不该啊。

public class WxExhibitionImageService extends BaseService
   
     {
       @Autowired    private TExhibitionImageMapper exhibitionImageMapper;    @Override    protected BaseMapper
    
      getMapper(){        return exhibitionImageMapper;    }}
    
   

解决

@Servicepublic class WxExhibitionImageService extends BaseService
   
     {
       @Autowired    private TExhibitionImageMapper exhibitionImageMapper;    @Override    protected BaseMapper
    
      getMapper(){        return exhibitionImageMapper;    }}
    
   

总结：
