如何在Spring rest控制器中接收application/x-www-form-urlencoded请求参数

Question

我试图编写一个restendpoint，它接收application/x-www-form-urlencoded。但是endpoint不接受@requestbody或@requestparam的请求参数

我已经尝试使用MultiValueMap来获取请求参数。但我总是得到0个参数。是否有一种方法可以获取MultiValueMap或其他POJO类的请求值。

ad=&value=sometestvalue-这是application/x-www-form-urlencoded requestbody。我试着用邮递员来做这个请求

@RequestMapping(value = "/test/verification/pay/{id}", method = RequestMethod.POST,
            consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE)
@ResponseBody
public Response testVerificationPay(@PathVariable("id") long id, @RequestParam MultiValueMap formData,
                                           HttpServletRequest servletRequest, ServiceContext serviceContext){
        log.info("!--REQUEST START--!"+formData.toString()); 
} 

Answer 1

您需要使用multivalueMap

@RequestMapping(value = "/test/verification/pay/{id}", method = RequestMethod.POST, consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE)
    @ResponseBody
    public Response testVerificationPay(@PathVariable("id") long id, @RequestParam MultiValueMap<String, String> formData) {
        System.out.println("!--REQUEST START--!" + formData.toString());
        return null;
    }
