网上对比解析框架性能优劣的帖子一大堆，但是很少有人针对这几个框架对数据格式和类型的兼容性分析，实际开发中由于客户端和服务端协调不到位引起的这些问题还是值得注意的。

结论如下：
1.格式不对照：json支持兼容更好，部分内容格式不对照仍可以解析成功。
2.key不对照：同样支持key不对照或缺少情况
3.value类型不对照(重点)：int-float都支持，float-int只有json支持，”“-float/int只有json支持，String解析为数值类型都是不支持的 Json兼容性支持更好。
4.泛型嵌套：同样支持泛型嵌套
5.内部类嵌套：同样支持内部类嵌套，但是fastjson对嵌套的内部类要求第三层内部类是静态的才可以正确解析，否则会异常如下：
com.alibaba.fastjson.JSONException: create instance error,class com.example.pcbin.myapplication.jsonvsgson.NestingBean$DataThree
，而gson没有这个要求。

总结：总的来说fastjson兼容性支持更好。改成fastjson注意排查所有三层嵌套的bean，第三层bean必须为static。

测试代码如下：

    Log.e("格式不对照-Gson-正确格式：",resultBeanGson.toString());
    try {
      BaseBean resultBeanGsonStyle = new Gson().fromJson(jsonError,BaseBean.class);
      Log.e("格式不对照-Gson-错误格式：",resultBeanGsonStyle.toString());
    }catch (Exception e){
      Log.e("格式不对照-Gson-错误格式：",e.toString());
    }
    BaseBean resultBeanJson = JSON.parSEObject(jsonStr,BaseBean.class);
    BaseBean resultBeanJsonStyle = JSON.parSEObject(jsonError,BaseBean.class);
    Log.e("格式不对照-JSON-正确格式：",resultBeanJson.toString());
    Log.e("格式不对照-JSON-错误格式：",resultBeanJsonStyle.toString());
