Fastjson DataBind数据库绑定

Fastjson 完全支持数据库绑定方法databind, 也非常易于使用.

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.addUser(guestUser);group.addUser(rootUser); String jsonString = JSON.toJSONString(group); System.out.println(jsonString);

Output

{"id":0,"name":"admin","users":[{"id":2,"name":"guest"},{"id":3,"name":"root"}]}

Decode

String jsonString = ...; Group group = JSON.parseObject(jsonString, Group.class);

Group.java

public class Group { private Long id; private String name; private List users = new ArrayList(); 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 getUsers() { return users; } public void setUsers(List users) { this.users = users; } public void addUser(User user) { users.add(user); } }

User.java

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; } }
