Constructor Detail

GemFireOperationsSessionRepository

public GemFireOperationsSessionRepository(org.springframework.data.gemfire.GemfireOperations template)

Constructs a new instance of GemFireOperationsSessionRepository initialized with the required GemfireOperations object used to perform data access operations for managing (HTTP) Session state.

Parameters:

template - GemfireOperations object used to access and manage Session state in GemFire.

See Also:

GemfireOperations

Method Detail

createSession

@NonNull
public org.springframework.session.Session createSession()

Constructs a new Session instance backed by GemFire.

Returns:

an instance of Session backed by GemFire.

See Also:

AbstractGemFireOperationsSessionRepository.GemFireSession.create(), Session, AbstractGemFireOperationsSessionRepository.configure(Session)

findById

@Nullable
public org.springframework.session.Session findById(java.lang.String sessionId)

Finds an existing, non-expired Session by ID. If the Session is expired, then the Session is deleted and null is returned.

Parameters:

sessionId - String containing the ID} of the Session to get.

Returns:

an existing Session by ID or null if no Session exists or the Session expired.

AbstractGemFireOperationsSessionRepository.GemFireSession.from(Session), GemfireTemplate.get(Object), Session, AbstractGemFireOperationsSessionRepository.getSessionsTemplate(), prepare(Session), AbstractGemFireOperationsSessionRepository.delete(Session)

findByIndexNameAndIndexValue

public java.util.Map<java.lang.String,org.springframework.session.Session> findByIndexNameAndIndexValue(java.lang.String indexName,
                                                                                                        java.lang.String indexValue)

Finds all available Sessions with the particular attribute indexed by name having the given value.

Parameters:

indexName - name of the indexed Session attribute. (e.g. FindByIndexNameSessionRepository.PRINCIPAL_NAME_INDEX_NAME).

indexValue - value of the indexed Session attribute to search on (e.g. username).

Returns:

a mapping of Session.getId() Session IDs} to Session objects.

See Also:

GemfireTemplate.find(String, Object...), Session, Map, AbstractGemFireOperationsSessionRepository.getSessionsTemplate(), prepareQuery(String), prepare(Session)

prepareQuery

protected java.lang.String prepareQuery(java.lang.String indexName)

Prepares the appropriate Pivotal GemFire OQL query based on the indexed Session attribute name.

Parameters:

indexName - a String indicating the name of the indexed Session attribute.

Returns:

an appropriate Pivotal GemFire OQL statement for querying on a particular indexed Session attribute.

See Also:

AbstractGemFireOperationsSessionRepository.getSessionsRegionName()

save

public void save(@Nullable
                 org.springframework.session.Session session)

Saves the specified Session to Apache Geode or Pivotal GemFire. Warning, the save method should never be called asynchronously and concurrently, from a separate Thread, while the caller continues to modify the given Session from the forking Thread or data loss can occur! There is a reason why this method is blocking!

Parameters:

session - the Session to save.

GemfireOperations.put(Object, Object), Session, isNonNullAndDirty(Session), doSave(Session)

deleteById

public void deleteById(java.lang.String sessionId)

Deletes (removes) any existing Session from GemFire. This operation also results in a SessionDeletedEvent.

Parameters:

sessionId - a String indicating the ID of the Session to remove from GemFire.

GemfireOperations.remove(Object), AbstractGemFireOperationsSessionRepository.handleDeleted(String, Session)
