spring注入通过注解方式实现
public class LoginForUserAction extends ActionSupportExtend {
?
?@Autowired
?private TbUserService tbUserService;
?
}
public interface TbUserService {}
@Service
public class TbUserServiceImpl implements TbUserService {
?
?@Autowired
?private TbuserDAO tbuserDAO;
}
public interface TbuserDAO {}
@Repository
public class TbuserDAOImpl extends DataAccess implements TbuserDAO {}
---------------------------------------------
在一次开发中 Action 中的Service实现类总是没有注入进来，通过仔细查找才发现，在ServiceImpl上没有添加@Service注解。。立刻悲剧类
