DefaultSessionManager

public DefaultSessionManager()

Method Detail

setSessionDAO

public void setSessionDAO(SessionDAO sessionDAO)

getSessionDAO

public SessionDAO getSessionDAO()

getSessionFactory

public SessionFactory getSessionFactory()

Returns the SessionFactory used to generate new Session instances. The default instance is a SimpleSessionFactory.

Returns:

the SessionFactory used to generate new Session instances.

Since:

1.0

setSessionFactory

public void setSessionFactory(SessionFactory sessionFactory)

Sets the SessionFactory used to generate new Session instances. The default instance is a SimpleSessionFactory.

Parameters:

sessionFactory - the SessionFactory used to generate new Session instances.

Since:

1.0

isDeleteInvalidSessions

public boolean isDeleteInvalidSessions()

Returns true if sessions should be automatically deleted after they are discovered to be invalid, false if invalid sessions will be manually deleted by some process external to Shiro's control. The default is true to ensure no orphans exist in the underlying data store.

Usage

It is ok to set this to false ONLY if you have some other process that you manage yourself that periodically deletes invalid sessions from the backing data store over time, such as via a Quartz or Cron job. If you do not do this, the invalid sessions will become 'orphans' and fill up the data store over time.

This property is provided because some systems need the ability to perform querying/reporting against sessions in the data store, even after they have stopped or expired. Setting this attribute to false will allow such querying, but with the caveat that the application developer/configurer deletes the sessions themselves by some other means (cron, quartz, etc).

Returns:

true if sessions should be automatically deleted after they are discovered to be invalid, false if invalid sessions will be manually deleted by some process external to Shiro's control.

Since:

1.0

setDeleteInvalidSessions

public void setDeleteInvalidSessions(boolean deleteInvalidSessions)

Sets whether or not sessions should be automatically deleted after they are discovered to be invalid. Default value is true to ensure no orphans will exist in the underlying data store.

WARNING

Only set this value to false if you are manually going to delete sessions yourself by some process (quartz, cron, etc) external to Shiro's control. See the isDeleteInvalidSessions() JavaDoc for more.

Parameters:

deleteInvalidSessions - whether or not sessions should be automatically deleted after they are discovered to be invalid.

Since:

1.0

setCacheManager

public void setCacheManager(CacheManager cacheManager)

Description copied from interface: CacheManagerAware

Sets the available CacheManager instance on this component.

Specified by:
