####################################java控制器######################################
@Controller
public class LoginController {
@Autowired
protected UserService userService;
@RequestMapping(value = "/login", method = RequestMethod.GET)
public String login() {
userService.findUserByLoginName("aa");
return "login";
}
}
####################################service实现类####################################
@Service
@Transactional(rollbackFor = Exception.class)
public class UserServiceImpl implements UserService {
@Autowired
private UserDao userDao;
@Override
public User findUserByLoginName(String loginName) {
System.out.println(userDao);// 不加Transactional的话就可以打打印出来，加了就进入不了这个类一样
return userDao.findByLoginName(loginName);
}
}
3 个解决方案
#1
注解加方法上边试试？
#2
@Service
@Transactional(rollbackFor = Exception.class)
改成：
@Service("UserService ")
@Transactional
@Transactional(rollbackFor = Exception.class)
改成：
@Service("UserService ")
@Transactional
#3
谢谢了啊，不是这个的问题，是因为数据库初始化的时候并没有主动链接，我在dataSource后面加入了 init-method="getConnection" 后就有用了
