JAVA中将控制台的JSON格式输出转换成数组

在我的JAVA项目中 每次运行后这行代码 System.out.println(securityResult);会输出
{"code":"0","msg":"SUCCESS","data":{"appSecret":"9b","time":"20180316110301","timeSecret":"8bf54"}}
我想知道怎么操作securityResult可以把data里面的数据转换成代码中的String appSecret = "9b";String time = "20180316110301"; String timeSrcret = "8bf54"

5个回答

使用net.sf.json包

 JSONObject object=JSONObject.fromObject(securityResult);
        JSONArray array=JSONArray.fromObject(object.get("data"));
        object=array.getJSONObject(0);
        String appSecret=(String)object.get("appSecret");
        String time=(String)object.get("time");
        String timeSecret=(String)object.get("timeSecret");

JSonObject或者GSON,你查下这两个类用法就知道了

阿里的fastjson.jar中有:
JSON.parseArray方法可实现,其他互转也都有。

String s = JSON.toJSONString(list);
JSON j = JSON.parseArray(s);

    System.out.println(j);
    return j;

JSONObject object=JSONObject.fromObject(securityResult);
JSONArray array=JSONArray.fromObject(object.get("data"));
object=array.getJSONObject(0);
String appSecret=(String)object.get("appSecret");
String time=(String)object.get("time");
String timeSecret=(String)object.get("timeSecret");

今天给你们讲述一个外包程序员的幸福生活。男主是Z哥,不是在外包公司上班的那种,是一名自由职业者,接外包项目自己干。接下来讲的都是真人真事。 先给大家介绍一下男主,Z哥,老程序员,是我十多年前的老同事,技术大牛,当过CTO,也创过业。因为我俩都爱好喝酒、踢球,再加上住的距离不算远,所以一直也断断续续的联系着,我对Z哥的状况也有大概了解。 Z哥几年前创业失败,后来他开始干起了外包,利用自己的技术能...

无代码时代来临,程序员如何保住饭碗?

编程语言层出不穷,从最初的机器语言到如今2500种以上的高级语言,程序员们大呼“学到头秃”。程序员一边面临编程语言不断推陈出新,一边面临由于许多代码已存在,程序员编写新应用程序时存在重复“搬砖”的现象。 无代码/低代码编程应运而生。无代码/低代码是一种创建应用的方法,它可以让开发者使用最少的编码知识来快速开发应用程序。开发者通过图形界面中,可视化建模来组装和配置应用程序。这样一来,开发者直...
