构造器详细资料

InMemoryWebSession

InMemoryWebSession(String id,
 Instant creationTime,
 Duration maxIdleTime)

方法详细资料

getId

public String getId()

从接口复制的说明: WebSession

returns this session's id

指定者:

getId 在接口中 WebSession

getCreationTime

public Instant getCreationTime()

从接口复制的说明: WebSession

Return the time when the session was created.

指定者:

getCreationTime 在接口中 WebSession

getLastAccessTime

public Instant getLastAccessTime()

从接口复制的说明: WebSession

Return the last time of session access as a result of user activity such as an HTTP request. Together with maxIdleTimeInSeconds this helps to determine when a session is expired.

指定者:

getLastAccessTime 在接口中 WebSession

setLastAccessTime

public void setLastAccessTime(Instant lastAccessTime)

从接口复制的说明: WebSession

Sets the last accessed time.

指定者:

setLastAccessTime 在接口中 WebSession

参数:

lastAccessTime - the last accessed time

changeSessionId

public void changeSessionId()

从接口复制的说明: WebSession

Generate a new id for the session and update the underlying session storage to reflect the new id. After a successful call WebSession.getId() reflects the new session id.

指定者:

changeSessionId 在接口中 WebSession

doInvalidate

protected void doInvalidate()

覆盖:

doInvalidate 在类中 AbstractWebSession

save

public void save()

从接口复制的说明: WebSession

Save the session through the SessionRepository as follows:

• If the session is new (i.e. created but never persisted), it must have been started explicitly via WebSession.start() or implicitly by adding attributes, or otherwise this method should have no effect.
• If the session was retrieved through the WebSessionStore, the implementation for this method must check whether the session was invalidated and if so return an error.

Note that this method is not intended for direct use by applications. Instead it is automatically invoked just before the response is committed.

指定者:

save 在接口中 WebSession

setMaxIdleTime

public void setMaxIdleTime(Duration maxIdleTime)

从接口复制的说明: WebSession

Configure the max amount of time that may elapse after the lastAccessTime before a session is considered expired. A negative value indicates the session should not expire.

指定者:

setMaxIdleTime 在接口中 WebSession

getMaxIdleTime

public Duration getMaxIdleTime()

从接口复制的说明: WebSession

Return the maximum time after the lastAccessTime before a session expires. A negative time indicates the session doesn't expire.

指定者:

getMaxIdleTime 在接口中 WebSession

start

public void start()

Force the creation of a session causing the session id to be sent when save() is called.

指定者:

start 在接口中 WebSession

isStarted

public boolean isStarted()

Whether a session with the client has been started explicitly via start() or implicitly by adding session attributes. If "false" then the session id is not sent to the client and the save() method is essentially a no-op.

指定者:

isStarted 在接口中 WebSession

attributeBinding

protected boolean attributeBinding(Object value,
 @Nullable
 Object oldValue)

覆盖:

attributeBinding 在类中 AbstractWebSession

allowAttributeReplaced

protected boolean allowAttributeReplaced(Object value,
 @Nullable
 Object oldValue)

覆盖:

allowAttributeReplaced 在类中 AbstractWebSession

checkMaxSessionsLimit

private void checkMaxSessionsLimit()

isExpired

public boolean isExpired()

从接口复制的说明: WebSession

Return true if the session expired after maxIdleTime elapsed.

Typically expiration checks should be automatically made when a session is accessed, a new WebSession instance created if necessary, at the start of request processing so that applications don't have to worry about expired session by default.

指定者:

isExpired 在接口中 WebSession

isExpired

private boolean isExpired(Instant now)

checkExpired

private boolean checkExpired(Instant currentTime)

writeObjectData

public void writeObjectData(ObjectOutputStream stream)
                     throws IOException

从接口复制的说明: SerializableSession

Write a serialized version of the contents of this session object to the specified object output stream, without requiring that the StandardSession itself have been serialized.

指定者:

writeObjectData 在接口中 SerializableSession

参数:

stream - The object output stream to write to

抛出:

IOException - if an input/output error occurs

readObjectData

public void readObjectData(ObjectInputStream stream)
                    throws ClassNotFoundException,
IOException

从接口复制的说明: SerializableSession

Read a serialized version of the contents of this session object from the specified object input stream, without requiring that the StandardSession itself have been serialized.

指定者:

readObjectData 在接口中 SerializableSession

参数:

stream - The object input stream to read from

抛出:

ClassNotFoundException - if an unknown class is specified

IOException - if an input/output error occurs

equals

public boolean equals(Object o)

覆盖:

equals 在类中 Object

hashCode

public int hashCode()

覆盖:

hashCode 在类中 AbstractWebSession
