Class JdbcOperationsSessionRepository

java.lang.Object

org.springframework.session.jdbc.JdbcOperationsSessionRepository

All Implemented Interfaces:

FindByIndexNameSessionRepository<org.springframework.session.jdbc.JdbcOperationsSessionRepository.JdbcSession>, SessionRepository<org.springframework.session.jdbc.JdbcOperationsSessionRepository.JdbcSession>

public class JdbcOperationsSessionRepository
extends Object
implements FindByIndexNameSessionRepository<org.springframework.session.jdbc.JdbcOperationsSessionRepository.JdbcSession>

A SessionRepository implementation that uses Spring's JdbcOperations to store sessions in a relational database. This implementation does not support publishing of session events.

An example of how to create a new instance can be seen below:

 JdbcTemplate jdbcTemplate = new JdbcTemplate();

 // ... configure jdbcTemplate ...

 PlatformTransactionManager transactionManager = new DataSourceTransactionManager();

 // ... configure transactionManager ...

 JdbcOperationsSessionRepository sessionRepository =
         new JdbcOperationsSessionRepository(jdbcTemplate, transactionManager);
 

For additional information on how to create and configure JdbcTemplate and PlatformTransactionManager, refer to the Spring Framework Reference Documentation.

By default, this implementation uses SPRING_SESSION and SPRING_SESSION_ATTRIBUTES tables to store sessions. Note that the table name can be customized using the setTableName(String) method. In that case the table used to store attributes will be named using the provided table name, suffixed with _ATTRIBUTES. Depending on your database, the table definition can be described as below:

 CREATE TABLE SPRING_SESSION (
   SESSION_ID CHAR(36),
   CREATION_TIME BIGINT NOT NULL,
   LAST_ACCESS_TIME BIGINT NOT NULL,
   MAX_INACTIVE_INTERVAL INT NOT NULL,
   PRINCIPAL_NAME VARCHAR(100),
   CONSTRAINT SPRING_SESSION_PK PRIMARY KEY (SESSION_ID)
 );

 CREATE INDEX SPRING_SESSION_IX1 ON SPRING_SESSION (LAST_ACCESS_TIME);

 CREATE TABLE SPRING_SESSION_ATTRIBUTES (
  SESSION_ID CHAR(36),
  ATTRIBUTE_NAME VARCHAR(200),
  ATTRIBUTE_BYTES BYTEA,
  CONSTRAINT SPRING_SESSION_ATTRIBUTES_PK PRIMARY KEY (SESSION_ID, ATTRIBUTE_NAME),
  CONSTRAINT SPRING_SESSION_ATTRIBUTES_FK FOREIGN KEY (SESSION_ID) REFERENCES SPRING_SESSION(SESSION_ID) ON DELETE CASCADE
 );

 CREATE INDEX SPRING_SESSION_ATTRIBUTES_IX1 ON SPRING_SESSION_ATTRIBUTES (SESSION_ID);
 

Due to the differences between the various database vendors, especially when it comes to storing binary data, make sure to use SQL script specific to your database. Scripts for most major database vendors are packaged as org/springframework/session/jdbc/schema-*.sql, where * is the target database type.

createSession

public org.springframework.session.jdbc.JdbcOperationsSessionRepository.JdbcSession createSession()

Description copied from interface: SessionRepository

Creates a new Session that is capable of being persisted by this SessionRepository.

This allows optimizations and customizations in how the Session is persisted. For example, the implementation returned might keep track of the changes ensuring that only the delta needs to be persisted on a save.

Specified by:

createSession in interface SessionRepository<org.springframework.session.jdbc.JdbcOperationsSessionRepository.JdbcSession>

Returns:

a new Session that is capable of being persisted by this SessionRepository

save

public void save(org.springframework.session.jdbc.JdbcOperationsSessionRepository.JdbcSession session)

Description copied from interface: SessionRepository

Ensures the Session created by SessionRepository.createSession() is saved.

Some implementations may choose to save as the Session is updated by returning a Session that immediately persists any changes. In this case, this method may not actually do anything.

Specified by:

save in interface SessionRepository<org.springframework.session.jdbc.JdbcOperationsSessionRepository.JdbcSession>

Parameters:

session - the Session to save

getSession

public org.springframework.session.jdbc.JdbcOperationsSessionRepository.JdbcSession getSession(String id)

Description copied from interface: SessionRepository

Gets the Session by the Session.getId() or null if no Session is found.

Specified by:

getSession in interface SessionRepository<org.springframework.session.jdbc.JdbcOperationsSessionRepository.JdbcSession>

Parameters:

id - the Session.getId() to lookup

Returns:

the Session by the Session.getId() or null if no Session is found.

delete

public void delete(String id)

Description copied from interface: SessionRepository

Deletes the Session with the given Session.getId() or does nothing if the Session is not found.

Specified by:

delete in interface SessionRepository<org.springframework.session.jdbc.JdbcOperationsSessionRepository.JdbcSession>

Parameters:

id - the Session.getId() to delete

findByIndexNameAndIndexValue

public Map<String,org.springframework.session.jdbc.JdbcOperationsSessionRepository.JdbcSession> findByIndexNameAndIndexValue(String indexName,
                                                                                                                             String indexValue)

Description copied from interface: FindByIndexNameSessionRepository

Find a Map of the session id to the Session of all sessions that contain the session attribute with the name FindByIndexNameSessionRepository.PRINCIPAL_NAME_INDEX_NAME and the value of the specified principal name.

Specified by:

findByIndexNameAndIndexValue in interface FindByIndexNameSessionRepository<org.springframework.session.jdbc.JdbcOperationsSessionRepository.JdbcSession>

Parameters:

indexName - the name if the index (i.e. FindByIndexNameSessionRepository.PRINCIPAL_NAME_INDEX_NAME)

indexValue - the value of the index to search for.

Returns:

a Map (never null) of the session id to the Session of all sessions that contain the session specified index name and the value of the specified index name. If no results are found, an empty Map is returned.
