看了那么多,搞了这么久,一个 @CrossOrigin注解解决所有问题!!!
在Controller层注解@CrossOrigin;
@CrossOrigin
@Controller
public class UserController { // http://localhost:8080/Sun/src/main/java/controller/UserController/select
@Autowired
private UserDao userDao;
do something ...
}
然后在方法层,注解请求的方式,POST或GET, 即
@RequestMapping(value = "/demo", method = RequestMethod.POST)
