== Distributed Transactions with JTA
Spring Boot supports distributed JTA transactions across multiple XA resources by using either an https://www.atomikos.com/[Atomikos] or https://github.com/bitronix/btm[Bitronix] embedded transaction manager.
Spring Boot supports distributed JTA transactions across multiple XA resources by using an https://www.atomikos.com/[Atomikos] embedded transaction manager.
Deprecated support for using a https://github.com/bitronix/btm[Bitronix] embedded transaction manager is also provided but it will be removed in a future release.
JTA transactions are also supported when deploying to a suitable Java EE Application Server.
When a JTA environment is detected, Spring's `JtaTransactionManager` is used to manage transactions.

=== Using a Bitronix Transaction Manager
https://github.com/bitronix/btm[Bitronix] is a popular open-source JTA transaction manager implementation.
NOTE: As of Spring Boot 2.3, support for Bitronix has been deprecated and will be removed in a future release.
You can use the `spring-boot-starter-jta-bitronix` starter to add the appropriate Bitronix dependencies to your project.
As with Atomikos, Spring Boot automatically configures Bitronix and post-processes your beans to ensure that startup and shutdown ordering is correct.

The interfaces are responsible for wrapping `XAConnectionFactory` and `XADataSource` beans and exposing them as regular `ConnectionFactory` and `DataSource` beans, which transparently enroll in the distributed transaction.
DataSource and JMS auto-configuration use JTA variants, provided you have a `JtaTransactionManager` bean and appropriate XA wrapper beans registered within your `ApplicationContext`.
