Question

我实现了2个ControllersAdvice。处理异常 CommonAdvice和UserAdvice

通用建议

@ControllerAdvice(annotations = RestController.class)
public class CommonAdvice {

    @ExceptionHandler(Exception.class)
    public ResponseEntity<ExceptionBean> handleException(Exception e) {
        ExceptionBean exception = new ExceptionBean(Causes.ANOTHER_CAUSE);
        return new ResponseEntity<ExceptionBean>(exception, HttpStatus.INTERNAL_SERVER_ERROR);
    }

}

UserAdvice

@ControllerAdvice(assignableTypes = { requestUserMapper.class })
public class UserAdvice {

    @ExceptionHandler(NotUniqueUserLoginException.class)
    public ResponseEntity<ExceptionBean> handleAlreadyFound(NotUniqueUserLoginException e) {
        System.out.println("this is me : " + Causes.USER_ALREADY_EXIST.toString());
        ExceptionBean exception = new ExceptionBean(Causes.USER_ALREADY_EXIST);
        return new ResponseEntity<ExceptionBean>(exception, HttpStatus.INTERNAL_SERVER_ERROR);
    }

现在，当我抛出NotUniqueUserException时，这是一个处理和异常的CommonAdvice。

我测试过，UserAdvice工作正常。有没有办法设置这个类的优先级？

@Edit - 添加Controllel Mapping

@RequestMapping(value = "add", method = RequestMethod.POST)
public ResponseEntity<GT_User> addUser(@RequestBody GT_User newUser) throws NotUniqueUserLoginException, Exception {

    if (this.userService.exist(newUser.getLogin())) {
        throw new NotUniqueUserLoginException(Causes.USER_ALREADY_EXIST.toString());
    } else {
        GT_User addesUser = this.userService.addUser(newUser);
        return new ResponseEntity<GT_User>(addesUser, HttpStatus.OK);
    }
}

在添加时为ControllerAdvice设置更高的优先级：

import org.springframework.core.Ordered;
import org.springframework.core.annotation.Order;
import com.genealogytree.webapplication.dispatchers.requestUserMapper;

@ControllerAdvice(assignableTypes = { requestUserMapper.class })
@Order(Ordered.HIGHEST_PRECEDENCE)
public class UserAdvice {
...
}

在添加

时将较低优先级设置为ControolerAdvice

import org.springframework.core.Ordered;
import org.springframework.core.annotation.Order;
import com.genealogytree.webapplication.dispatchers.requestUserMapper;

@ControllerAdvice(assignableTypes = { requestUserMapper.class })
@Order(Ordered.LOWEST_PRECEDENCE)
public class CommonAdvice {
...
}

如何通过ControllerAdvice在ExceptionHandling中设置优先级
