Spring mvc throwing org.springframework.web.HttpMediaTypeNotAcceptableException: Could not find acceptable representation
提问by user1647708
I am using springMVC and I am getting following exception when trying to do an update.
我正在使用 springMVC 并且在尝试进行更新时出现以下异常。
10:10:49,847 DEBUG LogicalConnectionImpl:250 - Released JDBC connection
10:10:49,859 DEBUG FixedContentNegotiationStrategy:48 - Requested media types is text/html (based on default MediaType)

10:10:49,941 DEBUG DefaultListableBeanFactory:246 - Returning cached instance of singleton bean 'org.springframework.context.annotation.internalScheduledAnnotationProcessor'
following is the controller method that throws the exception. Is there something that I need to do to make this work?
以下是引发异常的控制器方法。有什么我需要做的事情吗？
@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;
}
I found following post Spring MVC - HttpMediaTypeNotAcceptableExceptionwhere similar problem was discussed but I am not sure how to go about solving this with annotation.
我发现以下帖子Spring MVC - HttpMediaTypeNotAcceptableException讨论了类似的问题，但我不确定如何使用注释解决这个问题。
Any idea?
任何的想法？

The exception was thrown because of the return value of the controller. Once I changed the return value the exception went away.
由于控制器的返回值而引发异常。一旦我更改了返回值，异常就消失了。
public @ResponseBody String updateJob(@RequestParam(value="job_id") String job_id){
I also changed the response to be null.
我还将响应更改为空。
@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;
}

你可以试试这个：
@RequestMapping(value = "audit/unaudit", method = RequestMethod.GET,produces = "application/json")
