org.json.JSONObject对象转json,json新增元素，根据json的key获取值。以及list对象格式字符串转jsonArray

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：

package testMap.bean;

public class ZzcAntifraudReport_reasonCode {
	String ee;
	String ff;
	public String getEe() {
		return ee;
	}
	public void setEe(String ee) {
		this.ee = ee;
	}
	public String getFf() {
		return ff;
	}
	public void setFf(String ff) {
		this.ff = ff;
	}

}

复制

package testMap.bean;

public class ZzcAntifraudReport_blacklistRecordsList {
	String aa;
	String bb;
	public String getAa() {
		return aa;
	}
	public void setAa(String aa) {
		this.aa = aa;
	}
	public String getBb() {
		return bb;
	}
	public void setBb(String bb) {
		this.bb = bb;
	}
	
}

package testMap.bean;

public class ZzcAntifraudReport_antifraudHittedRulesList {
	String cc;

		this.cc = cc;

	public String getDd() {

	@Override
	public String toString() {
