Spring 如何在@ExceptionHandler方法中检索请求后对象/参数

我有一个controllerAdvice/@ExceptionHandler方法。我需要在ExceptionHandler方法中访问我的请求参数。 我可以用getRequestURI（）检索URI，但不知道如何检索POST请求参数 我有一些标识符参数，必须与ExceptionResponse一起发送回去。我该怎么做

    @ExceptionHandler(HttpClientErrorException.class)
    @ResponseStatus(value = HttpStatus.BAD_REQUEST)
    public @ResponseBody MyResponse handleResourceNotFound(final HttpClientErrorException ex,
            final HttpServletRequest request) {
        String str = request.getRequestURI();
        System.out.println(str);
        MyResponse response = new MyResponse(ex.getResponseBodyAsString(), 0, "-1");
        return response;
    }

这方面没有直接的方法。在我的情况下，我确实喜欢以下内容

控制器

@PostMapping("/test/")
@ResponseBody
public boolean isExist(@RequestBody Person person, HttpServletRequest request) {
    request.setAttribute("requestBody", person);
    int i = 1/0;
    return person != null && person.isExist();
}

@ExceptionHandler(HttpClientErrorException.class)
@ResponseStatus(value = HttpStatus.BAD_REQUEST)
public @ResponseBody MyResponse handleResourceNotFound(final HttpClientErrorException ex,
        final HttpServletRequest request) {
    String str = request.getRequestURI();
    System.out.println(request.getAttribute("requestBody"));
    MyResponse response = new MyResponse(ex.getResponseBodyAsString(), 0, "-1");
    return response;
}

异常处理程序

@PostMapping("/test/")
@ResponseBody
public boolean isExist(@RequestBody Person person, HttpServletRequest request) {
    request.setAttribute("requestBody", person);
    int i = 1/0;
    return person != null && person.isExist();
}

@ExceptionHandler(HttpClientErrorException.class)
@ResponseStatus(value = HttpStatus.BAD_REQUEST)
public @ResponseBody MyResponse handleResourceNotFound(final HttpClientErrorException ex,
        final HttpServletRequest request) {
    String str = request.getRequestURI();
    System.out.println(request.getAttribute("requestBody"));
    MyResponse response = new MyResponse(ex.getResponseBodyAsString(), 0, "-1");
    return response;
}
