User Group:
public class User {
private Long id;
private String name;
public Long getId() { return id; }
public void setId(Long id) { this.id = id; }
public String getName() { return name; }
public void setName(String name) { this.name = name; }
}
public class Group {
private Long id;
private String name;
private List<User> users = new ArrayList<User>();
public Long getId() { return id; }
public void setId(Long id) { this.id = id; }
public String getName() { return name; }
public void setName(String name) { this.name = name; }
public List<User> getUsers() { return users; }
public void setUsers(List<User> users) { this.users = users; }
}
Encode :
import com.alibaba.fastjson.JSON;
Group group = new Group();
group.setId(0L);
group.setName("admin");
User guestUser = new User();
guestUser.setId(2L);
guestUser.setName("guest");
User rootUser = new User();
rootUser.setId(3L);
rootUser.setName("root");
group.getUsers().add(guestUser);
group.getUsers().add(rootUser);
String jsonString = JSON.toJSONString(group);
System.out.println(jsonString);
Decode :
Group group2 = JSON.parseObject(jsonString, Group.class);
