Example 1 with OptimisticLockRetryInterceptor

use of org.drools.persistence.jpa.OptimisticLockRetryInterceptor in project jbpm by kiegroup.

the class SingletonRuntimeManagerTest method testInterceptorAfterRollback.

@Test

    RuntimeEngine runtime = manager.getRuntimeEngine(EmptyContext.get());
    KieSession ksession = runtime.getKieSession();
    ProcessInstance processInstance = ksession.startProcess("UserTaskWithRollback");
    ExecutableRunner commandService = ((CommandBasedStatefulKnowledgeSession) ksession).getRunner();
    assertEquals(PersistableRunner.class, commandService.getClass());
    ChainableRunner internalCommandService = ((PersistableRunner) commandService).getChainableRunner();
    assertEquals(ExecutionErrorHandlerInterceptor.class, internalCommandService.getClass());
    internalCommandService = (ChainableRunner) ((ExecutionErrorHandlerInterceptor) internalCommandService).getNext();
    assertEquals(TransactionLockInterceptor.class, internalCommandService.getClass());
    TaskService taskService = runtime.getTaskService();
    List<Long> taskIds = taskService.getTasksByProcessInstanceId(processInstance.getId());
    taskService.start(taskIds.get(0), "john");
    HashMap<String, Object> result = new HashMap<String, Object>();
    result.put("output1", "rollback");
    try {
        // rollback transaction
        taskService.complete(taskIds.get(0), "john", result);
    } catch (WorkflowRuntimeException e) {
    // ignore
    }
    result = new HashMap<String, Object>();
    result.put("output1", "ok");
    // this time, execute normally
    taskService.complete(taskIds.get(0), "john", result);
    internalCommandService = ((PersistableRunner) commandService).getChainableRunner();
    assertEquals(ExecutionErrorHandlerInterceptor.class, internalCommandService.getClass());
    internalCommandService = (ChainableRunner) ((ExecutionErrorHandlerInterceptor) internalCommandService).getNext();
    assertEquals(TransactionLockInterceptor.class, internalCommandService.getClass());
    internalCommandService = (ChainableRunner) ((TransactionLockInterceptor) internalCommandService).getNext();
    assertEquals(OptimisticLockRetryInterceptor.class, internalCommandService.getClass());
    internalCommandService = (ChainableRunner) ((OptimisticLockRetryInterceptor) internalCommandService).getNext();
    assertEquals("org.drools.persistence.PersistableRunner$TransactionInterceptor", internalCommandService.getClass().getName());
    // close manager which will close session maintained by the manager
    manager.close();
}

Example 2 with OptimisticLockRetryInterceptor

use of org.drools.persistence.jpa.OptimisticLockRetryInterceptor in project jbpm by kiegroup.

the class JPASessionFactory method addInterceptors.

protected void addInterceptors(KieSession ksession) {
    PersistableRunner runner = (PersistableRunner) ((CommandBasedStatefulKnowledgeSession) ksession).getRunner();
    runner.addInterceptor(new OptimisticLockRetryInterceptor());
    // even though it's added always TransactionLockInterceptor is by default disabled so won't do anything
    runner.addInterceptor(new TransactionLockInterceptor(ksession.getEnvironment()));
    runner.addInterceptor(new ExecutionErrorHandlerInterceptor(ksession.getEnvironment()));
}
