Json转list二层解析转换代码实例
一层结构的数据：
{
"code":"0",
"results":{
"boyTotal":0,
"classNumber":0,
"enrollmentsTotal":0,
"girlTotal":0,
"mobile":"15969538305",
"studentTotal":0,
"userCode":"141920370",
"userName":"杜文兵",
"userType":"1"
}
}
二层结构的数据：
{
"code":"0",
"results":{
"arrayList":[
{
"boyNumber":61,
"classId":"159",
"className":"17建筑工程技术01",
"deptName":"建筑工程学院",
"enrollments":61,
"girlNumber":0,
"majorName":"建筑工程技术",
"studentNumber":61,
"year":"2017"

"deptName":"建筑工程学院",
"enrollments":56,
"girlNumber":1,
"majorName":"建筑工程技术",
"studentNumber":56,
"year":"2017"
},
{
"boyNumber":56,
"classId":"209",
"className":"17建筑工程技术03",

先上代码：
JSONObjectobj1=newJSONObject();
obj1.put("mobile","13008662173");
//查询员工编号
JSONObjectuserInfo=ToolsWebReq.sendPost(ToolsWebReq.TEACHER_SERVER_BASE_URL+ToolsWebReq.API_QUERYUSERID,obj1);
ListuserInfos=(List)JsonUtils.JsonToList(userInfo.get("results"),newUserInfo());
StringuserCode="";
if(userInfos!=null){
for(inti=0;iclassLists=(List)JsonUtils.JsonToList(rs.get("arrayList"),newUserClassInfo());
System.out.println("classLists.get(0).getClassName()="+classLists.get(0).getClassName());
方法：
packagecom.xy.common.util;
importjava.util.List;
importnet.sf.json.JSONArray;
importnet.sf.json.JsonConfig;
publicclassJsonUtils{
/**
*json转对象
*
*@paraminput
*@return
*/
publicstaticListJsonToList(Objectobject,ObjectclassModel){
JSONArrayarray=JSONArray.fromObject(object);
Listlist2=net.sf.json.JSONArray.toList(array,classModel,newJsonConfig());//参数1为要转换的JSONArray数据，参数2为要转换的目标数据，即List盛装的数据
returnlist2;
}
}
对象：
packagecom.xy.web.entity;
importjava.util.Date;
importjavax.persistence.*;
