自定义枚举类型检查

/*** 工单状态，使用字典：order_item_state*/
@CheckEnum(nullAble = true, enumType = OrderItemStateEnum.class)
private String workState;

注解类

import javax.validation.Payload;
import java.lang.annotation.*;/*** 校验是否是状态枚举中的项*/
@Target({ElementType.METHOD, ElementType.FIELD, ElementType.PARAMETER, ElementType.TYPE_USE})
