二. fastjson 解析json字符串为四种类型
1. JavaBean
Person person = JSON.parseObject(jsonString, Person.class);
2. List<JavaBean>
List<Person> listPerson =JSON.parseArray(jsonString, Person.class);
3. List<String>
List<String> listString = JSON.parseArray(jsonString, String.class);
4. List<Map<String,Object>>
List<Map<String, Object>> listMap = JSON.parseObject(jsonString, new TypeReference<List<Map<String,Object>>>(){});
(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 ,
