前端：
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">

<title>submitUserList_3</title>
<meta http-equiv="content-type" content="text/html; charset=utf-8">
<script th:src="@{/resources/js/js/jquery-3.3.1.min.js}"></script>
<script type="text/javascript" language="JavaScript"> function submitUserList_3() {alert("ok"); var customerArray = new Array(); //customerArray.push({id: "1", name: "李四", pwd: "123"}); //customerArray.push({id: "2", name: "张三", pwd: "332"}); //customerArray.push({title:"标题一",type:2,options:[{option:"选项一"},{option:"选项二"}]});

$.ajax({ url: "./questionShare", type: "POST", contentType : 'application/json;charset=utf-8', //设置请求头信息
dataType:"json", data: JSON.stringify(customerArray), //将Json对象序列化成Json字符串，JSON.stringify()原生态方法 //data: $.toJSON(customerArray), //将Json对象序列化成Json字符串，toJSON()需要引用jquery.json.min.js
success: function(data){ alert(data); }, error: function(res){ alert(res.responseText); } }); } </script>
</head>
<body>
<h1>submitUserList_3</h1>
<input id="submit" type="button" value="Submit" onclick="submitUserList_3();">
</body>
</html>
注：上面嵌套了多个对象：
({type:"",title:"",url:"",content:"",endTime:"",questionModels:[{title:"标题一",type:2,options:[{option:"选项一"},{option:"选项二"}]}]})
最外层对象
public class Share {
private Integer id;
private Integer type;
private String title;
private String url;
private String content;
private String time;
private String endTime;
private List<QuestionModel> questionModels;
}
---
questionModels对象：
public class QuestionModel{
private Integer id; //标识符
private String title; //标题
private Integer type; //分享类型
private List<Option> options; //选项
}
----
Options对象
public class Option {
private String option;
}
---
后台接收对象
@RequestMapping("/questionShare")
@ResponseBody
public String getTest3(@RequestBody List<Share> shares){
System.out.println("记录数："+shares.size());
return "success";
}
[{"type":"1","title":"母亲节","url":"","content":"","endTime":"","questionModels":[{"title":"标题一","type":2,"options":[{"option":"选项一"},{"option":"选项二"}]}]}]。
--------------
如果用字符串接收，这是数组类型，需要将"[]"去掉在转换为Java对象
@RequestMapping("updateShare")
@ResponseBody
public AjaxResult update(@RequestBody String string){
System.out.println("接收的参数："+ string );
JSONObject jsonObject = JSONObject.parseObject(string);
Share share = JSON.toJavaObject(jsonObject,Share.class );
int result = shareService.update(share);
if(result > 0){
return AjaxResult.ok();
}else{
return AjaxResult.build("false",null );
}
}
