Description: declaration: package: org.apache.catalina.session, class: JDBCStore

# Class JDBCStore

java.lang.Object
org.apache.catalina.util.LifecycleBase
org.apache.catalina.session.StoreBase
org.apache.catalina.session.JDBCStore

All Implemented Interfaces:
  `Lifecycle`, `Store`

Direct Known Subclasses:
  `DataSourceStore`

@Deprecated public class JDBCStore extends StoreBase
Deprecated.
Removed in Tomcat 10 and replaced by DataSourceStore with removal of legacy JDBC code
Implementation of the `Store` interface that stores serialized session objects in a database. Sessions that are saved are still subject to being expired based on inactivity.
