New Spring applicationContext started by activiti-rest

Hi,I have a Spring (3.2.2) managed web application using Activiti 5.12. I'm not having any issues with this configuration and Activiti performs as expected. The process engine is managed by Spring and has access to all the beans it needs. We have not been using activiti-explorer or activiti-rest

Here's what I ended up doing in case this helps somebody.

I added a ProcessEnginesInitializer class that extends org.activiti.engine.ProcessEngines. The bean's @PostConstruct method registers the Spring-managed process engine with ProcessEngines, sets ProcessEngines.isInitialized to true, and performs some other initializations that ProcessEngines normally does. Next, the org.activiti.rest.application.ActivitiRestServicesApplication bean's declaration needs to depend on the processEnginesInitializer (to ensure that the REST service is initialized after ProcessEngines has been initialized). This results in the REST API using the Spring-managed process engine and avoids the extra application context I mentioned before.


@Component("processEnginesInitializer")
public class ProcessEngineInitializer extends org.activiti.engine.ProcessEngines {

 protected static final Logger log = LoggerFactory.getLogger(ProcessEngineInitializer.class);

 @Inject
 private ProcessEngine processEngine;

 @PostConstruct
 public void contextInitialized() {
  String processEngineName = processEngine.getName();
  String resourceUrl = "applicationContext.xml"; // I'm not sure that this text matters so you may be able to set this to anything.
  ProcessEngineInfo processEngineInfo = new ProcessEngineInfoImpl(processEngineName, resourceUrl, null);
  processEngineInfosByName.put(processEngineName, processEngineInfo);
  processEngineInfosByResourceUrl.put(resourceUrl, processEngineInfo);
  registerProcessEngine(processEngine);
  isInitialized = true;
  ProcessEngine processEngine = ProcessEngineInitializer.getDefaultProcessEngine();
  if (processEngine == null) {
   log.error("Could not initialize Activiti");
  }
 }

 @PreDestroy
 public void contextDestroyed() {
  ProcessEngineInitializer.destroy();
 }
}


<bean id="activitiRest" class="org.activiti.rest.application.ActivitiRestServicesApplication" depends-on="processEnginesInitializer"/>
