首先设置好多类，并set值，制作一个比较复杂的含有map ,list ,等层级嵌套的对象
package testMap.test;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.Iterator;
import java.util.List;
import java.util.Map;
import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;
import testMap.bean.AllJava;
import testMap.bean.CreditData;
import testMap.bean.ZzcAntifraudReport_antifraudHittedRulesList;
import testMap.bean.ZzcAntifraudReport_blacklistRecordsList;
import testMap.bean.ZzcAntifraudReport_reasonCode;
public class TestClass {
public static void main(String[] args) {
// TODO Auto-generated method stub
ZzcAntifraudReport_antifraudHittedRulesList rule=new ZzcAntifraudReport_antifraudHittedRulesList();
rule.setCc("CC");
rule.setDd("dd");
ZzcAntifraudReport_antifraudHittedRulesList rule2=new ZzcAntifraudReport_antifraudHittedRulesList();
rule2.setCc("cc2");
rule2.setDd("dd2");
ZzcAntifraudReport_blacklistRecordsList records=new ZzcAntifraudReport_blacklistRecordsList();
records.setAa("aa");
records.setBb("bb");
ZzcAntifraudReport_reasonCode code=new ZzcAntifraudReport_reasonCode();
code.setEe("ee");
code.setFf("ff");
CreditData data=new CreditData();
List<ZzcAntifraudReport_antifraudHittedRulesList> rulesLists=new ArrayList<ZzcAntifraudReport_antifraudHittedRulesList>();
rulesLists.add(rule);
rulesLists.add(rule2);
data.setAntifraudHittedRulesList(rulesLists);
data.setZzcAntifraudReport_count(33);
data.setZzcAntifraudReport_id("tt");
AllJava allJava=new AllJava();
Map<String, Object> creditMapsMap=new HashMap<String, Object>();
creditMapsMap.put("creditData", data);
allJava.setCreditMap(creditMapsMap);
allJava.setIfsuccess(true);
//---------至此为复杂对象赋值完毕
//对象转json
JSONObject jsonObject=new JSONObject(allJava);
System.err.println("========"+jsonObject.toString());
// 输出的结果是：========{"ifsuccess":true,"creditMap":{"creditData":{"zzcAntifraudReport_executedAt":null,"resonCode":null,"zzcAntifraudReport_id":"tt","blacklistRecordsList":null,"zzcAntifraudReport_count":33,"zzcAntifraudReport_riskLevel":null,"antifraudHittedRulesList":[{"dd":"dd","cc":"CC"},{"dd":"dd2","cc":"cc2"}],"zzcAntifraudReport_tenantCount":0}}}
try {
//通过key值获取value的第一种方法
Object aaString=jsonObject.get("creditMap");
JSONObject jsonObject2=new JSONObject(aaString.toString());
Object aaString2=jsonObject2.get("creditData");
System.out.println(aaString2);
// 输出的结果是：{"zzcAntifraudReport_executedAt":null,"resonCode":null,"zzcAntifraudReport_id":"tt","blacklistRecordsList":null,"zzcAntifraudReport_count":33,"antifraudHittedRulesList":[{"dd":"dd","cc":"CC"},{"dd":"dd2","cc":"cc2"}],"zzcAntifraudReport_riskLevel":null,"zzcAntifraudReport_tenantCount":0}
JSONObject jsonObject3=new JSONObject(aaString2.toString());
//直接输出
System.out.println(jsonObject3.get("zzcAntifraudReport_id"));
// 输出结果是：tt
System.out.println(jsonObject3.get("antifraudHittedRulesList"));
// 输出结果是：[{"dd":"dd","cc":"CC"},{"dd":"dd2","cc":"cc2"}]
// 使用getString(),getInt()等自带方法获取值
String reportId=jsonObject3.getString("zzcAntifraudReport_id");
System.err.println("reportId"+reportId);//reportIdtt
int count=jsonObject3.getInt("zzcAntifraudReport_count");
System.err.println("count"+count);//count33
// 使用jsonArray 获取map或list<object>格式的字符串，转成jsonArray
Object list=jsonObject3.get("antifraudHittedRulesList");
JSONArray jsonArray =jsonObject3.getJSONArray("antifraudHittedRulesList");
for(int i=0;i<jsonArray.length();i++){
JSONObject jsonObject4=jsonArray.getJSONObject(i);
jsonObject4.get("dd");
jsonObject4.get("cc");
System.out.println("---"+jsonObject4.toString());
// ---{"dd":"dd","cc":"CC"}
// ---{"dd":"dd2","cc":"cc2"}
}
System.out.println(jsonArray);
// [{"dd":"dd","cc":"CC"},{"dd":"dd2","cc":"cc2"}]
// 使用getBoolean()获取boolean类型
boolean ifsuccess=jsonObject.getBoolean("ifsuccess");
System.err.println("ifsuccess="+ifsuccess);//ifsuccess=true
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
使用到的类：从里到外：

}
