Spring mvc拋出org.springframework.web.HttpMediaTypeNotAcceptableException：找不到可接受的表示

我正在使用springMVC，並且在嘗試執行更新時出現以下異常。Spring mvc拋出org.springframework.web.HttpMediaTypeNotAcceptableException：找不到可接受的表示

10:10:49,847 DEBUG LogicalConnectionImpl:250 - Released JDBC connection

以下是引發異常的控制器方法。我需要做些什麼來完成這項工作？

@RequestMapping(value="/updateJob", method=RequestMethod.GET) 
public @ResponseBody JobQueue updateJob(@RequestParam(value="job_id") String job_id, @RequestParam String test_id, @RequestParam(value="status") String status) { 
    JobQueue job = jobqueueService.getJob(Integer.parseInt(job_id)); 
    job.setTest_id(test_id); 
    job.setStatus(Integer.parseInt(status)); 
    jobqueueService.updateJob(job); 
    return job; 
}

我發現下面的帖子Spring MVC - HttpMediaTypeNotAcceptableException這裏討論類似的問題，但我不知道如何去用註解解決這個。

任何想法？

由於控制器的返回值而引發異常。一旦我改變了返回值，異常消失了。

public @ResponseBody String updateJob(@RequestParam(value="job_id") String job_id){

我也將響應更改爲空。

@RequestMapping(value="/updateJob", method=RequestMethod.GET) 
public @ResponseBody String updateJob(@RequestParam(value="job_id") String job_id){ 
    Integer jobid = Integer.parseInt(job_id); 

    JobQueue job = jobqueueService.getJob(jobid); 
    . 
    . 
    return null; 
}

但是小它是。永遠不要說這是一個寶貴的問題，寶貴的答案。我在某個地方是正確的，我只是忘了它。這幫助我迅速找到自己的錯誤。所以不要忽視這個問題。謝謝！！ –

@ user1647708：那麼如果我的退貨類型是列表？我應該返回什麼？ –

ü可以試試這個：

@RequestMapping(value = "audit/unaudit", method = RequestMethod.GET,produces = "application/json")
