我有一个 Spring MVC 控制器和一个异常处理程序。发生异常时，我希望异常处理程序记录请求中发送的所有 GET/POST 数据。如何做到这一点？

控制器：

@Controller
@RequestMapping("/foo")
public class FooController {
    private final FooService fooService;

    @PostMapping("/bar")
    @ResponseBody
    public BarObject doSomething(@RequestBody final FooContext context) 
    {
        return fooService.doSomething(context);
    }
}

异常处理程序：

@ControllerAdvice
public class ExceptionController {

    private final Logger log = LoggerFactory.getLogger(ExceptionController.class);

    @ResponseStatus(HttpStatus.BAD_REQUEST)
    @ExceptionHandler(Exception.class)
    @ResponseBody
    public ErrorMessage handleException(final HttpServletRequest request, final Exception exception) {
        //Retrieve request data 
        //request.getQueryString() 
        // How to get POST data if we cannot access @RequestBody?)
        log.error(request.getRequestURI(), exception);
        return new ErrorMessage(request.getRequestURI(), exception.getLocalizedMessage());
}
