所有已实现的接口：

LoginService, LifeCycle

public class JDBCLoginService
extends MappedLoginService

HashMapped User Realm with JDBC as data source. JDBCLoginService extends HashULoginService and adds a method to fetch user information from database. The login() method checks the inherited Map for the user. If the user is not found, it will fetch details from the database and populate the inherited Map. It then calls the superclass login() method to perform the actual authentication. Periodically (controlled by configuration parameter), internal hashes are cleared. Caching can be disabled by setting cache refresh interval to zero. Uses one database connection that is initialized at startup. Reconnect on failures. authenticate() is 'synchronized'. An example properties file for configuration is in $JETTY_HOME/etc/jdbcRealm.properties
