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());
            }
        }

}

注：在使用Gson类的时候在工程中要添加Gson.jar包。
