在之前的表中添加数据

#插入用户信息表
INSERT INTO user_info(uid,username,`password`,`name`,id_card_num) VALUES (null,‘admin‘,‘123456‘,‘超哥‘,‘133333333333333333‘);
INSERT INTO user_info(uid,username,`password`,`name`,id_card_num) VALUES (null,‘test‘,‘123456‘,‘孙悟空‘,‘155555555555555555‘);
#插入用户角色表
INSERT INTO `sys_role` (`id`,`available`,`description`,`role`) VALUES (null,0,‘管理员‘,‘admin‘);
INSERT INTO `sys_role` (`id`,`available`,`description`,`role`) VALUES (null,0,‘VIP会员‘,‘vip‘);
INSERT INTO `sys_role` (`id`,`available`,`description`,`role`) VALUES (null,1,‘测试‘,‘test‘);
#插入用户_角色关联表
INSERT INTO `sys_user_role` (`role_id`,`uid`) VALUES (1,1);
INSERT INTO `sys_user_role` (`role_id`,`uid`) VALUES (2,2);
#插入权限表
INSERT INTO `sys_permission` (`id`,`available`,`name`,`parent_id`,`parent_ids`,`permission`,`resource_type`,`url`) VALUES (null,0,‘用户管理‘,0,‘0/‘,‘userInfo:view‘,‘menu‘,‘userInfo/view‘);
INSERT INTO `sys_permission` (`id`,`available`,`name`,`parent_id`,`parent_ids`,`permission`,`resource_type`,`url`) VALUES (null,0,‘用户添加‘,1,‘0/1‘,‘userInfo:add‘,‘button‘,‘userInfo/add‘);
INSERT INTO `sys_permission` (`id`,`available`,`name`,`parent_id`,`parent_ids`,`permission`,`resource_type`,`url`) VALUES (null,0,‘用户删除‘,1,‘0/1‘,‘userInfo:del‘,‘button‘,‘userInfo/del‘);
#插入角色_权限表
INSERT INTO `sys_role_permission` (`permission_id`,`role_id`) VALUES (1,1);
INSERT INTO `sys_role_permission` (`permission_id`,`role_id`) VALUES (2,1);
INSERT INTO `sys_role_permission` (`permission_id`,`role_id`) VALUES (3,2);

根据上面的sql创建实体类

public class User {
    private Integer uid;
    private String username;
    private String password;
    private String name;
    private String id_card_num;
    private String state;
    private Set<Role> roles = new HashSet<>();
}

public class Role {
    private Integer id;
    private String role;
    private String description;
    private String available;
    private Set<User> users = new HashSet<>();
    private Set<Permission> permissions = new HashSet<>();
}

public class Permission {
    private Integer id;
    private Integer parent_id;
    private String parent_ids;
    private String permission;
    private String resource_type;
    private String url;
    private String name;
    private String available;
    private Set<Role> roles = new HashSet<>();
}

编写mapper

@Mapper
public interface UserMapper {
    User findByUserName(String userName);
    int insert(User user);
    int del(@Param("username") String username);
}

@Mapper
public interface RoleMapper {
    Set<Role> findRolesByUserId(@Param("uid") Integer uid);
}

@Mapper
public interface PermissionMapper {
    Set<Permission> findPermissionsByRoleId(@Param("roles") Set<Role> roles);
}
