1.说明

只讲解关键部分，详细看源码，文章下方捐赠或QQ联系捐赠获取。

2.功能展示

包括用户增删改查和分配角色。

3.业务模型

@Data
@EqualsAndHashCode(callSuper = false)
@Accessors(chain = true)
@TableName("sys_user")
public class SysUser implements Serializable {

    private static final long serialVersionUID = 1L;

    /**
     * id
     */
    @TableId(value = "id", type = IdType.AUTO)
    private Integer id;

    /**
     * 用户名
     */
    private String username;

    /**
     * 用户密码
     */
    private String password;

    /**
     * 真实姓名
     */
    private String truename;

    /**
     * 邮箱
     */
    private String email;

    /**
     * 电话
     */
    private String phone;

    /**
     * 所属部门ID
     */
    private Integer deptId;

    /**
     * 头像地址
     */
    //private String avatar;

    /**
     * 创建时间
     */
    @TableField(fill = FieldFill.INSERT)
    private Date createTime;

    /**
     * 创建人
     */
    private String createUser;

    /**
     * 修改时间
     */
    @TableField(fill = FieldFill.INSERT_UPDATE)
    private Date updateTime;

    /**
     * 修改人
     */
    private String updateUser;

    @TableField(exist=false)
    private String deptName;

    @TableField(exist=false)
    private SysRole role;

    @TableField(exist=false)
    private SysDept dept;

}
