This commit adds tests that verify that all Spring Session configuration classes can be used with @Import, and fixes JDBC and Hazelcast HttpSession configurations and Redis WebSession configuration.
At present, RedisIndexedHttpSessionConfiguration and JdbcHttpSessionConfiguration include [at]EnableScheduling annotated inner configuration classes that configure expired session cleanup jobs. This approach silently opts in users into general purpose task scheduling support provided by Spring Framework, which isn't something a library should do. Ideally, session cleanup jobs should only require a single thread dedicated to their execution and also one that doesn't compete for resources with general purpose task scheduling.
This commit updates RedisIndexedSessionRepository and JdbcIndexedSessionRepository to have them manage their own ThreadPoolTaskScheduler for purposes of running expired session cleanup jobs.
Closes gh-2136
This commit updates Docker images used in all the integration tests. Additionally, it updates JDBC session repository Oracle integration tests to run unconditionally.
This commit reduces the JDBC integration tests to only single (latest) version per RDBMS vendor, due to a growing number of integration tests. Additionally, the configuration of most containers is simplified due to improved defaults within the Testcontainers library.
At present, the SQL statement used to insert a session attribute record contains a nested select statement that verifies the existence of parent record in the session table. Such approach can be susceptible to deadlocks on certain RDMBSs.
This commit optimizes the SQL statement used to insert session attribute so that it doesn't perform a nested select statement.
Closes: #1550
This commit provides JdbcIndexedSessionRepository customizers for the following SQL dialects:
- PostgreSQL
- MySQL (also used by MariaDB)
- SQL Server
- IBM DB2
- Oracle
These customizers are intended to address the concurrency issues occurring on insert of new session attribute by applying SQL dialect specific SQL upsert/merge statement instead of a generic insert.
Closes: #1213
This commit extracts scheduling configurers that are used in Redis and JDBC configurations into nested configuration classes in order to avoid bean method references.
Resolves: #1516
This commit adds support for customizing session repository implementations (both SessionRepository and ReactiveSessionRepository) before initialization by introducing SessionRepositoryCustomizer and ReactiveSessionRepositoryCustomizer strategies.
Resolves: #1499
This commit introduces SaveMode enum that individual SessionRepository implementations use to allow customization of the way they handle save operation in terms of tracking delta of changes.
