JAVA使用Gson解析json数据，实例

封装类Attribute：
public class Attribute {
     
    private int id;
    private String name;
    private int age;
     
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public int getAge() {
        return age;
    }
    public void setAge(int age) {
        this.age = age;
    }
     
}
另一个封装类GsonDataAnalysis：

public class GsonDataAnalysis {
     
    private List<Attribute> list;
     
    public List<Attribute> getList() {
        return list;
    }
    public void setList(List<Attribute> list) {
        this.list = list;
    }
     
}
测试类Main方法：

/**
 * Gson解析json数据
 * @author ForeverLover
 * @version 2015-04-19
 */
public class GsonTest {
 
        public static void main(String[] args) {
            String sTotalString = "{\"list\": [" +
                    "{\"id\":\"1\",\"name\":\"Tom\",\"age\":\"12\"}," +
                    "{\"id\":\"2\",\"name\":\"Marry\",\"age\":\"18\"}" +
                "]}";
            Gson gson = new Gson();
            GsonDataAnalysis gda = gson.fromJson(
                    sTotalString, GsonDataAnalysis.class);
            for(int i = 0; i < gda.getList().size(); i ++) {
                System.out.print("ID号：" + gda.getList().get(i).getId() + " ");
                System.out.print("姓 名：" + gda.getList().get(i).getName() + " ");
                System.out.println("年 龄：" + gda.getList().get(i).getAge());
            }
        }
     
}
