public final class GormSpringDataSessionSupport
extends java.lang.Object

Binds a GORM-owned ClientSession into Spring Data MongoDB's thread-bound resources so that a MongoTemplate executes within the same MongoDB transaction GORM started.

This lives in org.springframework.data.mongodb because Spring Data's MongoResourceHolder (the resource a MongoTemplate looks up to discover an active session) is package-private. Only the holder construction needs that access; binding, unbinding and rebinding go through the public TransactionSynchronizationManager keyed by the MongoDatabaseFactory, so callers can treat the holder as an opaque object.

Invariant: GORM owns the ClientSession lifecycle (it commits/aborts and closes it). The holder bound here is effectively read-only for Spring Data — MongoTemplate only reads the session from it; nothing in this module asks Spring Data to commit or close the session, so there is no double-close.

Compatibility: this depends on the package-private MongoResourceHolder(ClientSession, MongoDatabaseFactory) constructor of Spring Data MongoDB (verified against the 5.x line shipped with Spring Boot 4). A change to that internal type would break compilation, which the dedicated coupling smoke test surfaces explicitly. Because this is a deliberate split package with Spring Data, this module is supported on the class path only and is not compatible with the Java Platform Module System (JPMS) module path.
