Demo of ignored @Transactional on method with @Async.

Transaction is not active in AsyncListener#handle method.

Change

	<parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>2.1.7.RELEASE</version>
		<relativePath/> <!-- lookup parent from repository -->
	</parent>

to

	<parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>1.5.22.RELEASE</version>
		<relativePath/> <!-- lookup parent from repository -->
	</parent>

Now, transaction is active for some reason in the same method.
