能不能给注解 MqConsumer 增加开关，并且支持spring 的变量 实现？

[zkname]

@Target({ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
@Inherited
public @interface MqConsumer {

    public static final String DEFAULT_GROUP = "DEFAULT";   // default group
    public static final String EMPTY_GROUP = "";            // empty group means consume broadcase message, will replace by uuid

    public static final String OPEN = "OPEN";
    public static final String CLOSE = "CLOSE";

    /**
     * @return
     */
    String group() default DEFAULT_GROUP;

    /**
     * @return
     */
    String topic();

    /**
     * @return
     */
    boolean transaction() default true;

    /**
     * 消费开关
     * @return
     */
    String open() default OPEN;

}

类似于
@MqConsumer(topic = "test_${xxl.mq.env}", open = "${xxl.mq.open}")
