控制器的返回值應被忽略

Question

對於測試的原因，我想有一個彈簧MVC控制器與一個返回值應該由彈簧忽視的方法簽名：

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

這是一個職位 - 請求控制器收到數據，如果一切正常，只需要response.setStatus(HttpServletResponse.SC_OK);。

• 隨着@ResponseBody它死在一個內部服務器錯誤500
• 沒有@ResponseBody春天嘗試解析視圖
• 隨着void的返回值，它工作正常

我可以告訴春天忽略我返回的對象？ 謝謝！

Answer 1

@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 
} 

然後單元測試doSaveAnswer()。
