Package jakarta.servlet
Interface ServletContainerInitializer
public interface ServletContainerInitializer
ServletContainerInitializers (SCIs) are registered via an entry in the file
META-INF/services/jakarta.servlet.ServletContainerInitializer that must be included in the JAR file that contains the
SCI implementation.
SCI processing is performed regardless of the setting of metadata-complete. SCI processing can be controlled per JAR file via fragment ordering. If absolute ordering is defined, then only the JARs included in the ordering will be processed for SCIs. To disable SCI processing completely, an empty absolute ordering may be defined.
SCIs register an interest in annotations (class, method or field) and/or types via the
HandlesTypes
annotation which is added to the class.
