我们激素让user表和role表是一对一的关系进行配置

@Entity
    @Table(name = "tb_user")
    @SequenceGenerator(name = "tb_user_sq",sequenceName = "tb_user_sqe")
    public class TbUser extends BaseEntity{ 
    
    
        /** * 用户名 */
        private String userName;
        /** * 登录名 */
        private String loginName;
        /** * 登陆密码 */
        private String passWord;
        /** * 手机号 */
        private String telPhone;
        /** * 一个用户只有一个角色 */
        private TbRole tbRole;
    
        public String getUserName() {
            return userName;
        }
    
        public void setUserName(String userName) {
            this.userName = userName;
        }
    
        public String getLoginName() {
            return loginName;
        }
    
        public void setLoginName(String loginName) {
            this.loginName = loginName;
        }
    
        public String getPassWord() {
            return passWord;
        }
    
        public void setPassWord(String passWord) {
            this.passWord = passWord;
        }
    
        public String getTelPhone() {
            return telPhone;
        }
    
        public void setTelPhone(String telPhone) {
            this.telPhone = telPhone;
        }
    
        @Id
        @Override
        @GeneratedValue(generator = "tb_user_sq",strategy = GenerationType.SEQUENCE)
        public Long getId() {
            return this.id;
        }
        @OneToOne
        @JoinColumn(name = "tb_role")
        public TbRole getTbRole() {
            return tbRole;
        }
    
        public void setTbRole(TbRole tbRole) {
            this.tbRole = tbRole;
        }
    }

role表中同样设置

@Entity
    @Table(name = "tb_role")
    @SequenceGenerator(name = "tb_role_sq",sequenceName = "tb_role_sqe")
    public class TbRole extends BaseEntity{ 
    
    
        @Override
        @Id
        @GeneratedValue(generator = "tb_role_sq",strategy = GenerationType.SEQUENCE)
        public Long getId() {
            return this.id;
        }
    
        private String roleName;
    
        private TbUser tbUser;
    
        public String getRoleName() {
            return roleName;
        }
    
        public void setRoleName(String roleName) {
            this.roleName = roleName;
        }
        @OneToOne
        @JoinColumn(name = "tb_user")
        public TbUser getTbUser() {
            return tbUser;
        }
    
        public void setTbUser(TbUser tbUser) {
            this.tbUser = tbUser;
        }
    }
