3.业务模型

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

    private static final long serialVersionUID = 1L;

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

    /**
     * 角色名称
     */
    private String roleName;

    /**
     * 角色编码
     */
    private String roleCode;

    /**
     * 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 List<SysUser> userList;

    @TableField(exist=false)
    private boolean checked;
