实例页面如下：

<script src="http://libs.baidu.com/jquery/1.9.0/jquery.js" type="text/javascript"></script>

<form id="form1" action="" method="post" enctype="multipart/form-data">

<input type="button" value="ajax提交" id="ajaxSub">
</form>
<script type="text/javascript" >
//此对象用来封装其他参数
function ParamList(firstParam,secondParam,thirdParam) {
this.firstParam = firstParam;
this.secondParam = secondParam;
this.thirdParam = thirdParam;
};
//事件
$("#ajaxSub").click(function () {
//存放对象参数的数组
var dataList = new Array();
var object = new ParamList("被申请人","男，","。");
dataList.push(object);
var object1 = new ParamList("仲裁庭认为","，","案涉商品签约价3319");

console.log(dataList);
//创建一个FormData对象，用来封装所需参数
var myform = new FormData();
//获取form表单中的文件
myform.append('file', $('#file')[0].files[0]);
//用户id
myform.append('userId','1');
//用户名称
myform.append('userName','张三');
//将对象数组转化成json串传递给后台
myform.append("paramList",JSON.stringify( dataList ));
//var fromData = $("#form1").serialize();
//发送ajax请求
$.ajax({

下列为后台controller接收前台传递参数的部分代码，只要是从MultipartHttpServletRequest获取附件信息。
@RequestMapping(value = "/api/verdict")
public JsonResult<String> grabWordFromVerdictPdf(@RequestParam(value = "userId", required = false) Integer userId,
@RequestParam(value = "userName", required = false) String userName,
@RequestParam(value = "paramList", required = false) String paramList,
MultipartHttpServletRequest request) {
Iterator<String> fileNames = request.getFileNames();
MultipartFile file = null;
JsonResult<String> jsonResult = new JsonResult<String>();
while (fileNames.hasNext()) {
String str = fileNames.next();
file = request.getFile(str);
}
if (file != null) {
String fileName = file.getOriginalFilename();
String suffix = "";
if (fileName != null) {
suffix = fileName.substring(fileName.indexOf("."), fileName.length());
}
String localPath = uploadFileConfig.getLocalPath();
String interPath = uploadFileConfig.getInterPath();
}
}
