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。
