java 解析json 万能型

上一篇c# 的万能型Json 解析，现在写一篇Java的万能型Json 解析

导入FastJson依赖

<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>fastjson</artifactId>
    <version>1.2.61</version>
</dependency>

使用JSON.parseObject()

    Object list = JSON.parseObject(jsonStr, new TypeReference<Object>(){});

比如解析一个User对象

    User user = JSON.parseObject(jsonStr, new TypeReference<User>(){});

解析Map，List

Map<String,String> list = JSON.parseObject(jsonStr, new TypeReference<Map<String,String>(){});
List<String> list = JSON.parseObject(jsonStr, new TypeReference<List<String>>(){})；
