fastjson 解析json字符串的四种类型

1. JavaBean

          Person person = JSON.parseObject(jsonString, Person.class);

      2. List

          List listPerson =JSON.parseArray(jsonString, Person.class);

      3. List

          List listString = JSON.parseArray(jsonString, String.class);

      4. List>

          List> listMap = JSON.parseObject(jsonString, new TypeReference>>(){});  (注意：此处可看出fastjson反射机制比gson更准确， id = 1001 通过fastjson反射仍是 id = 1001 , 而通过gson反射结果 为 id =1001.0 ,
