使用spring 3 restful以编程方式更改http响应状态 [英] Programmatically change http response status using spring 3 restful

问题描述

我有一个类似下面的控制器

I have a controller like below

@Controller("myController")
@RequestMapping("api")
public class MyController {

     @RequestMapping(method = RequestMethod.GET, value = "/get/info/{id}", headers = "Accept=application/json")
    public @ResponseBody
    Student getInfo(@PathVariable String info) {
.................
}




    @ExceptionHandler(Throwable.class)
    @ResponseStatus( HttpStatus.EXPECTATION_FAILED)
    @ResponseBody
    public String handleIOException(Throwable ex) {
        ErrorResponse errorResponse = errorHandler.handelErrorResponse(ex);
        return errorResponse.toString();
    }

}

控制器有错误处理机制，在错误处理选项中，它总是返回期望失败状态代码417.但是我需要设置动态错误Http状态代码，如500,403等，具体取决于错误类型。我该怎么做？

The controller has an error handling mechanism, in the error handling option it always return expectation fail status code 417. But I need to set a dynamic error Http status code like 500, 403 etc depending on type of error. How do I do this?

您需要更改输出值 ResponseEntity 的类型。在这里回答：
