1.json对象的属性的值是json对象,结构如下:

info属性为json对象

{
 "name":"zhangsan",
 "age":14,
 "info":{
           “address”:"bejing",
		   “school”:“北京一中”,
		   “class”:"六年级"
          }
}

2.json对象的属性的值是json数组,结构如下:

info属性为json数组

{
 "name":"zhangsan",
 "age":14,
 "info":[
          {
           “address”:"bejing",
		   “school”:“北京一中”,
		   “class”:"六年级"
          },
		  {
           “address”:"bejing",
		   “school”:“北京二中”,
		   “class”:"五年级"
          },
		  {
           “address”:"bejing",
		   “school”:“北京三中”,
		   “class”:"四年级"
          }
		]
}

3.判断json对象的属性的值是json对象还是json数组

判断info的值是json对象还是json数组,使用fastjson API

if (paramObj.getString("info").startsWith("["))
{   
    //属性值是json数组
	JSONArray jsonArray = JSONArray.fromObject(paramObj.get("attr"));
}
else if (paramObj.getString("info").startsWith("{"))
{   
    //属性值是json对象
	JSONObject jsonObject = JSONObject.fromObject(paramObj.get("attr"));
}
