# 37. 使用JTA处理分布式事务

Spring Boot通过[Atomkos](http://www.atomikos.com/)或[Bitronix](https://github.com/bitronix/btm)的内嵌事务管理器支持跨多个XA资源的分布式JTA事务，当部署到恰当的J2EE应用服务器时也会支持JTA事务。

当发现JTA环境时，Spring Boot将使用Spring的`JtaTransactionManager`来管理事务。自动配置的JMS，DataSource和JPA beans将被升级以支持XA事务。你可以使用标准的Spring idioms，比如`@Transactional`，来参与到一个分布式事务中。如果处于JTA环境，但仍想使用本地事务，你可以将`spring.jta.enabled`属性设置为`false`来禁用JTA自动配置功能。
