本文介绍 SpringBoot + Spring Data JPA + Thymeleaf 实现关注取消关注互相关注的功能。采用 Bootstrap + ajax 显示数据，样式是模仿慕课网,获取样式，点此直达。

本项目也使用了Spring Data JPA 分页功能，因为数据比较少，所以设置一页显示一个。

动态效果图如下，点击放大






一、数据库设计


user 表主要是有一个 id 主键， fan_size 粉丝数，follow_size 关注数 ；

relationship 表有两个字段 from_user_id，to_user_id ，组成联合主键。

本文使用的是是 Spring Data JPA，无需设计数据表，直接通过实体生成。




二、实体

  8. import java.io.Serializable;
  10. /**

  13.  */
  15. @Entity
  16. @Data
  17. public class User implements Serializable {
  19.     private static final long serialVersionUID = 6147345506206285446L;
  21.     @Id // 主键
  22.     @GeneratedValue(strategy = GenerationType.IDENTITY) // 自增长策略
  23.     private Integer id; // 用户的唯一标识
  25.     @NotEmpty(message = "昵称不能为空")

  27.     @Column(nullable = false, length = 12)
  28.     private String nickname;
  30.     @NotEmpty(message = "用户名不能为空")
  31.     @Size(min = 4, max = 20, message = "用户名长度必须为4-20个字符")
  32.     @Column(nullable = false, length = 20, unique = true)
  33.     private String username; // 用户账号，用户登录时的唯一标识
  35.     @NotEmpty(message = "密码不能为空")
  36.     @Size(max = 100, message = "密码长度最多100个字符")
  37.     @Column(length = 100)
  38.     private String password; // 登录时密码
  40.     @Column(length = 200)
  41.     @Size(max = 200, message = "头像链接长度最多200个字符")
  42.     private String avatar; // 头像图片地址
  45.     private Integer followSize = 0;//关注数
  47.     private Integer fanSize = 0; //粉丝数
  49.     @Transient
  50.     private Integer isFriend = 0;//关系，0表示没有关系，2表示互相关注
  53.     public User() {
  54.     }
  57. }

其他与本文无关的字段，这里省掉了。
