• 帮你找了个相似的问题, 你可以看下: https://ask.csdn.net/questions/7656908
• 这篇博客你也可以参考下：springmvc后台接收ajax参数
• 这篇博客也不错, 你可以看下springmvc后台接收ajax参数
• 除此之外, 这篇博客: springMVC接收ajax传的数组中的 springMVC接收前端ajax传的数组 部分也许能够解决你的问题, 你可以仔细阅读以下内容或跳转源博客中阅读:
  

• 在传递的过程中,直接使用@RequestParam接收,发现400错误
  首先是ajax如下:
  其中的参数都是数组

  // 请求后台设置域名
          $.ajax({
              url: basePath + '/modify_server_domain',
              type: 'post',
              data: {
                  appId: appId,
                  requestdomainList: requestDomainList,
                  wsrequestdomainList: socketDomainList,
                  uploaddomainList: uploadFileDomainList,
                  downloaddomainList: downloadFileDomainList
              },
           	dataType: 'json',
              success: function (res) {
                 console.log(res)
              }
          });
  

  后端的代码如下:
  @RequestMapping("/modify_server_domain")
  public R modifyServerDomain(@RequestParam(“appId”) String appId, @RequestParam(“requestdomainList”) List requestdomainList,
  @RequestParam(“wsrequestdomainList”) List wsrequestdomainList,
  @RequestParam(“uploaddomainList”) List uploaddomainList,
  @RequestParam(“downloaddomainList”) List downloaddomainList){
  try {
  WxOpenMaDomainResult mpServerDomain = weChatOpenService.modifyServerDomain(appId, requestdomainList,
  wsrequestdomainList, uploaddomainList, downloaddomainList);
  return R.ok(mpServerDomain);
  } catch (ApiException ae) {
  return R.failed(ae.getMessage());
  } catch (Exception e) {
  return R.failed(ResponseMessage.ERROR);
  }
  }

  最后发现,直接写参数名是不能接收的,解决办法就是加上[]
  即:
  @RequestMapping("/modify_server_domain")
  public R modifyServerDomain(@RequestParam(“appId”) String appId, @RequestParam(“requestdomainList[]”) List requestdomainList,
  @RequestParam(“wsrequestdomainList[]”) List wsrequestdomainList,
  @RequestParam(“uploaddomainList[]”) List uploaddomainList,
  @RequestParam(“downloaddomainList[]”) List downloaddomainList){
  try {
  WxOpenMaDomainResult mpServerDomain = weChatOpenService.modifyServerDomain(appId, requestdomainList,
  wsrequestdomainList, uploaddomainList, downloaddomainList);
  return R.ok(mpServerDomain);
  } catch (ApiException ae) {
  return R.failed(ae.getMessage());
  } catch (Exception e) {
  return R.failed(ResponseMessage.ERROR);
  }
  }
