M03 13 What is @EnableTransactionManagement for?

@EnableTransactionManagement annotation is used on top of @Configuration class to enable annotation-driven transaction management by @Transactional annotation in Spring Framework.

When @EnableTransactionManagement is used, TransactionInterceptor and TransactionAspectSupport will be used to proxy each call to @Transactional class or method, which will use PlatformTransactionManager to manage transaction.

@EnableTransactionManagement allows you to specify following values:

• Mode – sets advice mode for @Transactional annotation, indicates how calls to methods should be intercepted, PROXY is default mode, you can switch it to more advanced ASPECTJ weaving advice, which supports local calls
• Order – indicates order of advice execution when more then one advice applies to @Transactional join point
• proxyTargetClass – indicates whether CGLIB Proxy classes should be created or if JDK Proxies should be created (default), this field is used only when Mode is set to PROXY
