gson

一.json转javaBean

  (1).json转普通对象

     json字符串：{\"name\":\"rain\",\"age\":30}

    javaBean：      

public class Person {public String name;public int age;}

    代码：

Gson gson = new Gson();Person person = gson.fromJson(jsonStr, Person.class);

 

 (2).json转list对象

     json字符串：[{\"name\":\"rain\",\"age\":30}, {\"name\":\"rain\",\"age\":30}]

    javaBean：      

public class Person {public String name;public int age;}

    代码：

Gson gson = new Gson();List<Person> personList = gson.fromJson(jsonStr, new TypeToken<List<Person>>(){}.getType());

二.注解

public class Person {

<span style="white-space:pre">@SerializedName("real_name")</span>public String name;public int age;}
