Java如何将String转换成json对象或json数组

导包：

<dependency>
    <groupId>net.sf.json-lib</groupId>
    <artifactId>json-lib</artifactId>
    <version>2.4</version>
    <classifier>jdk15</classifier>
    <!-- jdk版本 -->
</dependency>

注意：这里会有个问题，无法自动导入依赖 

解决方案：

jar包下载地址：Json-lib - Browse Files at SourceForge.net

下载下来json-lib jar包后，jar包名字都带后缀啥jdk15等等；  这时候两种解决方案  

      一.直接把jar包复制到本地仓库的 net/sf/json-lib/2.4（你对应版本文件夹），jar包名字改成json-lib-2.4.jar，IDEA中重新import下maven项目即可使用JSONObject;  注意，目录下的lastUpdated文件记得删除掉!

      二.使用mvn  install命令把jar包安装到本地仓库（其中仓库地址、jar版本、以及下载下来jar的位置 记得改成自己的！）

mvn install:install-file  -DgroupId=net.sf.json-lib -DartifactId=json-lib  -Dversion=2.4 -Dpackaging=jar -Dfile=D:\firefoxDownload\Redhat6.8\json-lib-2.4-jdk15.jar

这样我们就可以使用JSONObject类了

将String转换成json对象或json数组

注意：json字符串中键的名称要和实体类一致。

 String datajson =
            "[" +
                "{" +
                    "'aliasName':'Taurus-49999787'," +
                    "'ftpPort':16602," +
                    "'hasPassWord':false," +
                    "'height':1080," +
                    "'ignoreTime':0," +
                    "'ip':'172.16.9.205'," +
                    "'key':'novaStar'," +
                    "'logined':false," +
                    "'loginedUsernames':[" +
                        "''" +
                    "]," +
                    "'password':''," +
                    "'platform':'rk312x'," +
                    "'privacy':true," +
                    "'productName':'TC300'," +
                    "'sn':'BZSA07194A0049999787'," +
                    "'syssetFtpPort':16604," +
                    "'syssetTcpPort':16605," +
                    "'tcpPort':16603," +
                    "'terminalState':5," +
                    "'username':[" +
                    "]," +
                    "'width':1920" +
                "}," +
                "{....}"+
            "]";
JSONArray jsonArray = JSONArray.parseArray(datajson);
for(int i=0; i<jsonArray.size(); i++) {
    JSONObject object = jsonArray.getJSONObject(i);
    Entity entity = JSONObject.parseObject(object.toJSONString() , Entity.class);// 将string类型直接封装成对象
    System.out.println(entity.toString());
}
