 fastjson 用于生成和解析 JSON 数据的简单示例

[代码] [Java]代码

01	public class User {

02	private Long id;

03	private String name;

04

05	public Long getId() { return id; }

06	public void setId(Long id) { this.id = id; }

07

08	public String getName() { return name; }

09	public void setName(String name) { this.name = name; }

10

}

[代码] [Java]代码

01	public class Group {

02	private Long id;

03	private String name;

04	private List<User> users = new ArrayList<User>();

05

06	public Long getId() { return id; }

07	public void setId(Long id) { this.id = id; }

08

09	public String getName() { return name; }

10	public void setName(String name) { this.name = name; }

11

12	public List<User> getUsers() { return users; }

13	public void setUsers(List<User> users) { this.users = users; }

14

}

[代码] 编码

01	import com.alibaba.fastjson.JSON;

02

03	Group group = new Group();

04	group.setId(0L);

05	group.setName("admin");

06

07	User guestUser = new User();

08	guestUser.setId(2L);

09	guestUser.setName("guest");

10

11	User rootUser = new User();

12	rootUser.setId(3L);

13	rootUser.setName("root");

14

15	group.getUsers().add(guestUser);

16	group.getUsers().add(rootUser);

17

18	String jsonString = JSON.toJSONString(group);

19

20	System.out.println(jsonString);

[代码] 输出结果

1

{

2	"name":"admin",

3	"id":0,"users":[

4	{"name":"guest","id":2},

5	{"name":"root","id":3}
