JAVA中如何将一个json形式的字符串转为json对象或对象列表

　　

import java.util.*;
import java.text.SimpleDateFormat;

import org.json.JSONObject;
import org.json.JSONArray;
import org.json.JSONException;



public class test_client {

    public static  void test(){
        //把json字符串转为json对象
        String js ="{"uniqueCode":"OTTCD015","terminalBrandCode":"10","equipmentBrand":"夏普"}";
        JSONObject jsonObj = new JSONObject(js);
        System.out.println(jsonObj.get("uniqueCode"));

        //把json字符串列表转为json对象列表
        String jslist ="[{"uniqueCode":"OTTCD015","terminalBrandCode":"10","equipmentBrand":"夏普"}," +
                "{"uniqueCode":"OTTCD016","terminalBrandCode":"30","equipmentBrand":"惠普"}]";
        JSONArray objar = new JSONArray(jslist);
        List<Object>  list = objar.toList();
        for(Object obj :list){
//            System.out.println(obj.toString());
            Map<String,Object> map = (HashMap<String,Object>)obj;
            Set<String> sets = map.keySet();
            for(String key:sets){
                System.out.println(key+": "+map.get(key));
            }
            System.out.println();
        }
    }

　　输出：

　　　　OTTCD015

　　　　uniqueCode: OTTCD015
　　　　terminalBrandCode: 10
　　　　equipmentBrand: 夏普

　　　　uniqueCode: OTTCD016
　　　　terminalBrandCode: 30
　　　　equipmentBrand: 惠普
