Extending Spring data's @Document annotation

Question

I am trying to wrap org.springframework.data.elasticsearch.annotations.Document into a custom annotation , MyDocument. @MyDocument will inherit everything that the parent @Document has, and the spring data library should also process MyDocument annotation that way it would do it for parent @Document.

Is this possible at all?

I tried below code, but I can't set the required 'indexName' param for @Document.

@Document() // HOW TO PUT indexName of @Mydocument into this?
@Persistent
@Inherited
@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.TYPE})
public @interface MyDocument {
     @AliasFor(annotation = Document.class, attribute = "indexName")
    String indexName();

    @AliasFor(annotation = Document.class, attribute = "useServerConfiguration")
    boolean useServerConfiguration() default false;

    @AliasFor(annotation = Document.class, attribute = "shards")
    short shards() default 1;

    @AliasFor(annotation = Document.class, attribute = "replicas")
    short replicas() default 1;

    @AliasFor(annotation = Document.class, attribute = "refreshInterval")
    String refreshInterval() default "1s";

    @AliasFor(annotation = Document.class, attribute = "indexStoreType")
    String indexStoreType() default "fs";

    @AliasFor(annotation = Document.class, attribute = "createIndex")
    boolean createIndex() default true;

    @AliasFor(annotation = Document.class, attribute = "versionType")
    VersionType versionType() default VersionType.EXTERNAL;

    // My document specific props
    String myCustomProp() default "myDefault";

    // more properties....


}

REFERENCE for @Document Annotation by spring data elasticsearch

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

    String indexName();
    @Deprecated
    String type() default "";
    boolean useServerConfiguration() default false;
    
    short shards() default 1;

    short replicas() default 1;

    String refreshInterval() default "1s";

    String indexStoreType() default "fs";

    boolean createIndex() default true;

    VersionType versionType() default VersionType.EXTERNAL;
}

EDITED : I actually needed to pass all the @Document params via this @MyDocument

EDIT#2 : Added @Document annotation class for reference

You are just missing the value argument of the @AliasFor annotation:

@Document() // HOW TO PUT indexName of @Mydocument into this?
@Persistent
@Inherited
@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.TYPE})
public @interface MyDocument {

    @AliasFor(value = "indexName", annotation = Document.class)
    String indexName();

    boolean useServerConfiguration() default false;

    short shards() default 1;

    short replicas() default 1;

    String refreshInterval() default "1s";

    String indexStoreType() default "fs";

    boolean createIndex() default true;

    VersionType versionType() default VersionType.EXTERNAL;

    // My document specific props
    String myCustomProp() default "myDefault";

    // more properties....


}

Note that this only works in spring-data-elasticsearch version 4.2.x (and above).
