本篇内容主要讲解"json数组怎么将字符串转list集合",感兴趣的朋友不妨来看看。本文介绍的方法操作简单快捷,实用性强。下面就让小编来带大家学习"json数组怎么将字符串转list集合"吧!
1.json字符串
json字符串与普通的字符串没有任何特殊的地方,但是之所以称为json字符串是因为,这个字符串符合我们之前介绍的语法规则。
2.json数组形式字符串转换为List的8种方法
package com.zkn.newlearn.json; import com.alibaba.fastjson.JSON;import com.alibaba.fastjson.JSONArray;import com.alibaba.fastjson.JSONObject; import java.util.List;import java.util.Map; /** * Created by zkn on 2016/8/22. */public class JsonToMapTest02 { public static void main(String[] args){ String strArr = "[{\"0\":\"zhangsan\",\"1\":\"lisi\",\"2\":\"wangwu\",\"3\":\"maliu\"}," + "{\"00\":\"zhangsan\",\"11\":\"lisi\",\"22\":\"wangwu\",\"33\":\"maliu\"}]"; //第一种方式 List listObjectFir = (List) JSONArray.parse(strArr); System.out.println("利用JSONArray中的parse方法来解析json数组字符串"); for(Map mapList : listObjectFir){ for (Map.Entry entry : mapList.entrySet()){ System.out.println( entry.getKey() + " " +entry.getValue()); } } //第二种方式 List listObjectSec = JSONArray.parseObject(strArr,List.class); System.out.println("利用JSONArray中的parseObject方法并指定返回类型来解析json数组字符串"); for(Map mapList : listObjectSec){ for (Map.Entry entry : mapList.entrySet()){ System.out.println( entry.getKey() + " " +entry.getValue()); } } //第三种方式 JSONArray listObjectThir = JSONArray.parseArray(strArr); System.out.println("利用JSONArray中的parseArray方法来解析json数组字符串"); for(Object mapList : listObjectThir){ for (Object entry : ((Map)mapList).entrySet()){ System.out.println(((Map.Entry)entry).getKey() + " " +((Map.Entry)entry).getValue()); } } //第四种方式 List listObjectFour = JSONArray.parseArray(strArr,Map.class); System.out.println("利用JSONArray中的parseArray方法并指定返回类型来解析json数组字符串"); for(Object mapList : listObjectFour){ for (Object entry : ((Map)mapList).entrySet()){ System.out.println(((Map.Entry)entry).getKey() + " " +((Map.Entry)entry).getValue()); } } //第五种方式 JSONArray listObjectFifth = JSONObject.parseArray(strArr); System.out.println("利用JSONObject中的parseArray方法来解析json数组字符串"); for(Object mapList : listObjectFifth){ for (Object entry : ((Map)mapList).entrySet()){ System.out.println(((Map.Entry)entry).getKey() + " " +((Map.Entry)entry).getValue()); } } //第六种方式 List listObjectSix = JSONObject.parseArray(strArr,Map.class); System.out.println("利用JSONObject中的parseArray方法并指定返回类型来解析json数组字符串"); for(Object mapList : listObjectSix){ for (Object entry : ((Map)mapList).entrySet()){ System.out.println(((Map.Entry)entry).getKey() + " " +((Map.Entry)entry).getValue()); } } //第七种方式 JSONArray listObjectSeven = JSON.parseArray(strArr); System.out.println("利用JSON中的parseArray方法来解析json数组字符串"); for(Object mapList : listObjectSeven){ for (Object entry : ((Map)mapList).entrySet()){ System.out.println(((Map.Entry)entry).getKey() + " " +((Map.Entry)entry).getValue()); } } //第八种方式 List listObjectEigh = JSONObject.parseArray(strArr,Map.class); System.out.println("利用JSON中的parseArray方法并指定返回类型来解析json数组字符串"); for(Object mapList : listObjectEigh){ for (Object entry : ((Map)mapList).entrySet()){ System.out.println(((Map.Entry)entry).getKey() + " " +((Map.Entry)entry).getValue()); } } }}到此,相信大家对"json数组怎么将字符串转list集合"有了更深的了解,不妨来实际操作一番吧!这里是网站,更多相关内容可以进入相关频道进行查询,关注我们,继续学习!
