Hello,
In order to use my own task and execution listener i had to remove @EnableProcessApplication annotation from my springboot application and define my own configuration extending SpringBootProcessApplication like:
@Configuration public class EngineConfiguration extends SpringBootProcessApplication { @Override public TaskListener getTaskListener() { System.out.println("I am here!"); return super.getTaskListener(); } @Override public ExecutionListener getExecutionListener() { System.out.println("I am here!"); return super.getExecutionListener(); } }
the issue is this below exception:
java.lang.IllegalStateException: Failed to load ApplicationContext at org.springframework.test.context.cache.DefaultCacheAwareContextLoaderDelegate.loadContext(DefaultCacheAwareContextLoaderDelegate.java:125) at org.springframework.test.context.support.DefaultTestContext.getApplicationContext(DefaultTestContext.java:108) at org.springframework.test.context.web.ServletTestExecutionListener.setUpRequestContextIfNecessary(ServletTestExecutionListener.java:190) at org.springframework.test.context.web.ServletTestExecutionListener.prepareTestInstance(ServletTestExecutionListener.java:132) at org.springframework.test.context.TestContextManager.prepareTestInstance(TestContextManager.java:246) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.createTest(SpringJUnit4ClassRunner.java:227) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner$1.runReflectiveCall(SpringJUnit4ClassRunner.java:289) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.methodBlock(SpringJUnit4ClassRunner.java:291) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.runChild(SpringJUnit4ClassRunner.java:246) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.runChild(SpringJUnit4ClassRunner.java:97) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:290) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:71) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:288) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:58) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:268) at org.springframework.test.context.junit4.statements.RunBeforeTestClassCallbacks.evaluate(RunBeforeTestClassCallbacks.java:61) at org.springframework.test.context.junit4.statements.RunAfterTestClassCallbacks.evaluate(RunAfterTestClassCallbacks.java:70) at org.junit.runners.ParentRunner.run(ParentRunner.java:363) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.run(SpringJUnit4ClassRunner.java:190) at org.junit.runner.JUnitCore.run(JUnitCore.java:137) at com.intellij.junit4.JUnit4IdeaTestRunner.startRunnerWithArgs(JUnit4IdeaTestRunner.java:68) at com.intellij.rt.execution.junit.IdeaTestRunner$Repeater.startRunnerWithArgs(IdeaTestRunner.java:47) at com.intellij.rt.execution.junit.JUnitStarter.prepareStreamsAndStart(JUnitStarter.java:242) at com.intellij.rt.execution.junit.JUnitStarter.main(JUnitStarter.java:70) Caused by: java.lang.RuntimeException: java.lang.ClassCastException: java.util.Optional cannot be cast to java.lang.String at org.camunda.bpm.engine.spring.application.SpringProcessApplication.onApplicationEvent(SpringProcessApplication.java:104) at org.camunda.bpm.engine.spring.application.SpringProcessApplication.onApplicationEvent(SpringProcessApplication.java:51) at com.td.tds.veritas.security.rivendell.engine.EngineConfiguration$$EnhancerBySpringCGLIB$$a0dde9c7.onApplicationEvent(<generated>) at org.springframework.context.event.SimpleApplicationEventMulticaster.doInvokeListener(SimpleApplicationEventMulticaster.java:172) at org.springframework.context.event.SimpleApplicationEventMulticaster.invokeListener(SimpleApplicationEventMulticaster.java:165) at org.springframework.context.event.SimpleApplicationEventMulticaster.multicastEvent(SimpleApplicationEventMulticaster.java:139) at org.springframework.context.support.AbstractApplicationContext.publishEvent(AbstractApplicationContext.java:398) at org.springframework.context.support.AbstractApplicationContext.publishEvent(AbstractApplicationContext.java:355) at org.springframework.context.support.AbstractApplicationContext.finishRefresh(AbstractApplicationContext.java:882) at org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:549) at org.springframework.boot.SpringApplication.refresh(SpringApplication.java:775) at org.springframework.boot.SpringApplication.refreshContext(SpringApplication.java:397) at org.springframework.boot.SpringApplication.run(SpringApplication.java:316) at org.springframework.boot.test.context.SpringBootContextLoader.loadContext(SpringBootContextLoader.java:127) at org.springframework.test.context.cache.DefaultCacheAwareContextLoaderDelegate.loadContextInternal(DefaultCacheAwareContextLoaderDelegate.java:99) at org.springframework.test.context.cache.DefaultCacheAwareContextLoaderDelegate.loadContext(DefaultCacheAwareContextLoaderDelegate.java:117) ... 24 more Caused by: java.lang.ClassCastException: java.util.Optional cannot be cast to java.lang.String at java.util.Optional.ifPresent(Optional.java:159) at org.camunda.bpm.spring.boot.starter.SpringBootProcessApplication.afterPropertiesSet(SpringBootProcessApplication.java:85) at org.camunda.bpm.engine.spring.application.SpringProcessApplication.onApplicationEvent(SpringProcessApplication.java:95) ... 39 more
looks like that the attribute springApplicationName in SpringBootProcessApplication class resolves to Optional<Optional<String>> instead of Optional<String> which causes the above exception, i am not sure whether this is the spring issue or not, but i workaround it by reassigning the springApplicationName:
@Configuration public class EngineConfiguration extends SpringBootProcessApplication { ... @Override public void afterPropertiesSet() throws Exception { springApplicationName = Optional.empty(); super.afterPropertiesSet(); } }
setting application-name in application.properties didn't help.
my fix is not the best fix so i'd appreciate if you could look into this.
Thank you,
