java.lang.IllegalArgumentException: Not a managed type: class com.dengzhili.rbacdemo.entity.UmsRole

使用Spring Data JPA时。报错提示：java.lang.IllegalArgumentException: Not a managed type: class com.dengzhili.rbacdemo.entity.UmsRole。
原因：
UmsRole 实体类没有加@Entity注解，该实体类没有被Spring容器管理。Spring Data Repository 接口需要实体类被托管。所以报错

@Repository
public interface UmsRoleRepository extends JpaRepository<UmsRole,Long> {

}


@Data
@Table
@Entity  //去掉启动报错
public class UmsRole {

    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;

    //名称
    private String name;
    //描述
    private String description;

    //创建时间
    private Date createTime;

    //启用状态：0->禁用；1->启用
    private Integer status;

    private Integer sort;

//    private Set<UmsPermission> permissions = new HashSet<UmsPermission>();
}
