Question

我有@RabbitListener(id="example", queues={"a", "b"})监听器，我在不同模块的代码中复制粘贴在多个位置。我想创建一个别名，例如：

@Target({ ElementType.TYPE, ElementType.METHOD, ElementType.ANNOTATION_TYPE })
@Retention(RetentionPolicy.RUNTIME)
@MessageMapping
@Documented
public @interface MyRabbitListener {

    @AliasFor(annotation = RabbitListener.class)
    String id() default "example";

    @AliasFor(annotation = RabbitListener.class)
    String containerFactory() default "";

    @AliasFor(annotation = RabbitListener.class)
    String[] queues() default {"a", "b"};

    @AliasFor(annotation = RabbitListener.class)
    boolean exclusive() default false;

    @AliasFor(annotation = RabbitListener.class)
    String priority() default "";

    @AliasFor(annotation = RabbitListener.class)
    String admin() default "";

    @AliasFor(annotation = RabbitListener.class)
    QueueBinding[] bindings() default {};

    @AliasFor(annotation = RabbitListener.class)
    String group() default "";
}

然后我只是在我的方法上使用@MyRabbitListener，但它不起作用，因为我认为还没有spring-amqp模块的别名支持。有什么方法可以注册我的别名吗？

我刚刚意识到我犯了一个愚蠢的错误并没有正确创建别名。它应该是这样的：

@Target({ ElementType.TYPE, ElementType.METHOD, ElementType.ANNOTATION_TYPE })
@Retention(RetentionPolicy.RUNTIME)
@MessageMapping
@Documented
@RabbitListener(id = "example", queues = {"a", "b"})
public @interface MyRabbitListener {

    @AliasFor(annotation = RabbitListener.class)
    String containerFactory() default "";

    @AliasFor(annotation = RabbitListener.class)
    boolean exclusive() default false;

    @AliasFor(annotation = RabbitListener.class)
    String priority() default "";

    @AliasFor(annotation = RabbitListener.class)
    String admin() default "";

    @AliasFor(annotation = RabbitListener.class)
    QueueBinding[] bindings() default {};

    @AliasFor(annotation = RabbitListener.class)
    String group() default "";
}

我可以创建一个Spring RabbitListener别名吗？
