Class JdbcIndexedSessionRepository

java.lang.Object
org.springframework.session.jdbc.JdbcIndexedSessionRepository
All Implemented Interfaces:
org.springframework.beans.factory.DisposableBean, org.springframework.beans.factory.InitializingBean, FindByIndexNameSessionRepository<org.springframework.session.jdbc.JdbcIndexedSessionRepository.JdbcSession>, SessionRepository<org.springframework.session.jdbc.JdbcIndexedSessionRepository.JdbcSession>
public class JdbcIndexedSessionRepository extends Object implements FindByIndexNameSessionRepository<org.springframework.session.jdbc.JdbcIndexedSessionRepository.JdbcSession>, org.springframework.beans.factory.InitializingBean, org.springframework.beans.factory.DisposableBean
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 ...

 TransactionTemplate transactionTemplate = new TransactionTemplate();

 // ... configure transactionTemplate ...

 JdbcIndexedSessionRepository sessionRepository =
         new JdbcIndexedSessionRepository(jdbcTemplate, transactionTemplate);
For additional information on how to create and configure JdbcTemplate and TransactionTemplate, 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 (
   PRIMARY_ID CHAR(36) NOT NULL,
   SESSION_ID CHAR(36) NOT NULL,
   CREATION_TIME BIGINT NOT NULL,
   LAST_ACCESS_TIME BIGINT NOT NULL,
   MAX_INACTIVE_INTERVAL INT NOT NULL,
   EXPIRY_TIME BIGINT NOT NULL,
   PRINCIPAL_NAME VARCHAR(100),
   CONSTRAINT SPRING_SESSION_PK PRIMARY KEY (PRIMARY_ID)
 );

 CREATE UNIQUE INDEX SPRING_SESSION_IX1 ON SPRING_SESSION (SESSION_ID);
 CREATE INDEX SPRING_SESSION_IX2 ON SPRING_SESSION (EXPIRY_TIME);
 CREATE INDEX SPRING_SESSION_IX3 ON SPRING_SESSION (PRINCIPAL_NAME);

 CREATE TABLE SPRING_SESSION_ATTRIBUTES (
  SESSION_PRIMARY_ID CHAR(36) NOT NULL,
  ATTRIBUTE_NAME VARCHAR(200) NOT NULL,
  ATTRIBUTE_BYTES BYTEA NOT NULL,
  CONSTRAINT SPRING_SESSION_ATTRIBUTES_PK PRIMARY KEY (SESSION_PRIMARY_ID, ATTRIBUTE_NAME),
  CONSTRAINT SPRING_SESSION_ATTRIBUTES_FK FOREIGN KEY (SESSION_PRIMARY_ID) REFERENCES SPRING_SESSION(PRIMARY_ID) ON DELETE CASCADE
 );

 CREATE INDEX SPRING_SESSION_ATTRIBUTES_IX1 ON SPRING_SESSION_ATTRIBUTES (SESSION_PRIMARY_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.JdbcIndexedSessionRepository.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.JdbcIndexedSessionRepository.JdbcSession>
      Returns:
      a new Session that is capable of being persisted by this SessionRepository

    • save

      public void save(org.springframework.session.jdbc.JdbcIndexedSessionRepository.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.JdbcIndexedSessionRepository.JdbcSession>
      Parameters:
      session - the Session to save

    • findById

      public org.springframework.session.jdbc.JdbcIndexedSessionRepository.JdbcSession findById(String id)
      Description copied from interface: SessionRepository
      Gets the Session by the Session.getId() or null if no Session is found.
      Specified by:
      findById in interface SessionRepository<org.springframework.session.jdbc.JdbcIndexedSessionRepository.JdbcSession>
      Parameters:
      id - the Session.getId() to lookup
      Returns:
      the Session by the Session.getId() or null if no Session is found.

    • deleteById

      public void deleteById(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:
      deleteById in interface SessionRepository<org.springframework.session.jdbc.JdbcIndexedSessionRepository.JdbcSession>
      Parameters:
      id - the Session.getId() to delete

    • findByIndexNameAndIndexValue

      public Map<String,org.springframework.session.jdbc.JdbcIndexedSessionRepository.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 specified index name index value.
      Specified by:
      findByIndexNameAndIndexValue in interface FindByIndexNameSessionRepository<org.springframework.session.jdbc.JdbcIndexedSessionRepository.JdbcSession>
      Parameters:
      indexName - the name of 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 specified index name and index value. If no results are found, an empty Map is returned.
