Process applications

By default, the operaton-spring-boot-starter is configured to use the SpringProcessEngineConfiguration auto deployment feature. Since 1.2.0 you also have the possibility to do so via SpringBootProcessApplication. This disables the SpringProcessEngineConfiguration auto-deploy feature and instead uses the required META-INF/processes.xml as an indicator for resource scanning. This also allows all processes.xml configuration features described [here] (../process-applications/the-processes-xml-deployment-descriptor.md).

To use it, just add the @EnableProcessApplication annotation to your Spring Boot application class:

@SpringBootApplication
@EnableProcessApplication("myProcessApplicationName")
public class MyApplication {

...

}

Some configuration can be done via Spring Boot configuration parameters. Check the list of currently available parameters.

Using Deployment Callbacks

As when using @EnableProcessApplication we don't extend the ProcessApplication class, we can't use @PostDeploy and @PreUndeploy method annotations. Instead these callbacks are provided via Spring event publishing mechanism. So you can use the following event listeners:

@EventListener
public void onPostDeploy(PostDeployEvent event) {
  ...
}

@EventListener
public void onPreUndeploy(PreUndeployEvent event) {
  ...
}
