在Spring 3中是否可以动态设置@ResponseStatus的原因？ [英] In Spring 3 is it possible to dynamically set the reason of @ResponseStatus?

问题描述

我有一个自定义的异常类，注释为返回给定的 HttpStatus ：

I have a custom exception class annotated to return a given HttpStatus:

@ResponseStatus(value=HttpStatus.BAD_REQUEST, reason="Invalid parameter")
public class BadRequestException extends RuntimeException
{
  public BadRequestException(String msg)
  {
    super(msg);
  }
}

当我抛出来自我的控制器的BadRequestException 但原因始终是无效参数。有没有办法在这个类中设置返回的原因？我想传递一个字符串作为原因。

This works when I throw a BadRequestException from my controller but the reason is always "Invalid parameter" of course. Is there a way to set the returned reason in this class? I'd like to pass a string to be used as the reason.

谢谢！

推荐答案

你可以使用 response.sendError（HttpServletResponse.SC_BAD_REQUEST，无效的foo）;
