Class HibernateSearchJsr352Extension

java.lang.Object

org.hibernate.search.jsr352.jberet.impl.HibernateSearchJsr352Extension

All Implemented Interfaces:

javax.enterprise.inject.spi.Extension

public class HibernateSearchJsr352Extension
extends Object
implements javax.enterprise.inject.spi.Extension

A CDI extension to explicitly add hibernate-search-jsr352-core types to the CDI context.

These types must be registered into the CDI context because they expect one of their attributes to be injected, thus they need to be instantiated by CDI.

Ideally we should use component scanning to that effect, but:

• In CDI, component scanning is configured per-module in META-INF/beans.xml, with no way to add a package from another module.
• In Wildfly, component scanning in dependencies is always done with the "all" discovery type, meaning that even components without CDI annotations will be discovered. Besides exposing private types unnecessarily, this is annoying because it puts default EntityManagerFactoryRegistry implementations into the CDI context, leading to conflicts when injecting such types (since this module, hibernate-search-jsr352-jberet, also provides an implementation).
  See WFLY-8656.
• Even if we could solve the above, JBeret requires specific scope annotations to be set on the beans so that they are correctly scoped. Since the core isn't dependent on JBeret, we must specify these scopes manually when registering the beans.

Thus we use explicit type and scope registration as a workaround.
