控制器的返回值应被忽略

Question

对于测试的原因，我想有一个弹簧MVC控制器与一个返回值应该由弹簧忽视的方法签名：

@RequestMapping(value = "/{uuid}", params = "question", method = RequestMethod.POST) 
@ResponseBody 
public IAnswer saveAnswer(UiAnswer json, @PathVariable String uuid, @RequestParam("question") String question, HttpServletResponse response) {} 

这是一个职位 - 请求控制器收到数据，如果一切正常，只需要response.setStatus(HttpServletResponse.SC_OK);。

• 随着@ResponseBody它死在一个内部服务器错误500
• 没有@ResponseBody春天尝试解析视图
• 随着void的返回值，它工作正常

我可以告诉春天忽略我返回的对象？ 谢谢！

@RequestMapping(value = "/{uuid}", params = "question", method = RequestMethod.POST) 
@ResponseBody 
public void saveAnswer(UiAnswer json, 
         @PathVariable String uuid, 
         @RequestParam("question") String question, 
         HttpServletResponse response) { 
    doSaveAnswer(json, uuid, question, response); 
} 

protected IAnswer doSaveAnswer(UiAnswer json, 
           String uuid, 
           String question, 
           HttpServletResponse response) { 
    // your original code here 
} 

然后单元测试doSaveAnswer()。
