边界计时器在Activiti 6中不起作用

Question

我使用边界计时器，它不起作用。如果计时器之后没有元素，则过程继续此顺序流。如果计时器之后有服务任务，则过程将在正常路径上进行。这是我的bpm计划的一部分：

我使用Spring 5为Activiti创建bean。这是我的bean配置类的示例：

     @Bean
SpringProcessEngineConfiguration processEngineConfiguration(@Qualifier("dataSourceForActiviti") DataSource dataSourceForActiviti,
                                                            @Qualifier("transactionManagerForActiviti") PlatformTransactionManager transactionManagerForActiviti) {
    SpringProcessEngineConfiguration processEngineConfiguration = new SpringProcessEngineConfiguration();
    processEngineConfiguration.setTransactionManager(transactionManagerForActiviti);

    processEngineConfiguration.setDataSource(dataSourceForActiviti)
            .setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_TRUE)
            .setAsyncExecutorActivate(true)
    ;

    processEngineConfiguration.setDeploymentResources(new Resource[]{
            new ClassPathResource("bpm/LicensingProcess.bpmn20.xml"),
            new ClassPathResource("bpm/ReissuanceLicenseProcess.bpmn20.xml"),
            new ClassPathResource("bpm/IssueOfDuplicateProcess.bpmn20.xml"),
            new ClassPathResource("bpm/IssuanceOfCopyProcess.bpmn20.xml"),
            new ClassPathResource("bpm/TerminationOfLicenseProcess.bpmn20.xml"),
            new ClassPathResource("bpm/ExtractFromRegisterOfLicensesProcess.bpmn20.xml")
    });


    return processEngineConfiguration;
}

@Bean
ProcessEngineFactoryBean processEngineFactoryBean(SpringProcessEngineConfiguration processEngineConfiguration) {
    ProcessEngineFactoryBean processEngineFactoryBean = new ProcessEngineFactoryBean();
    processEngineFactoryBean.setProcessEngineConfiguration(processEngineConfiguration);
    return processEngineFactoryBean;
}

@Bean
RepositoryService repositoryService(ProcessEngineFactoryBean processEngineFactoryBean) throws Exception {
    return processEngineFactoryBean.getObject().getRepositoryService();
}

@Bean
RuntimeService runtimeService(ProcessEngineFactoryBean processEngineFactoryBean) throws Exception {
    return processEngineFactoryBean.getObject().getRuntimeService();
}

@Bean
TaskService taskService(ProcessEngineFactoryBean processEngineFactoryBean) throws Exception {
    return processEngineFactoryBean.getObject().getTaskService();
}

我尝试对setAsyncExecutorActivate(true)行进行注释和取消注释，没有区别。同时，如果将计时器作为一个单独的单元，则一切正常。

PS我刚刚找到了这样的解决方案（正在将其添加到'ProcessEngineConfiguration'bean的定义中）：

// Async Job Executor
final DefaultAsyncJobExecutor asyncExecutor = new DefaultAsyncJobExecutor();
asyncExecutor.setMaxPoolSize(50);
asyncExecutor.setQueueSize(100);
processEngineConfiguration.setAsyncExecutor(asyncExecutor);

但这也没有帮助我。尽管没有asyncJobExecutor是null。

PSS同时，类似的方案在Activiti Modeler中也可以很好地工作。而且我不明白为什么它在那里起作用而对我不起作用

PSSS我已经在Swing上编写了一个简单的应用程序，没有使用Spring。我使用了StandaloneProcessEngineConfiguration类，而没有使用SpringProcessEngineConfiguration和ProcessEngineFactoryBean类。它可以工作，但是如果我将服务任务或脚本任务放在boundary timer之后（而不是将计时器事件作为单独的元素），则它确实可以工作。它写道，它找不到用于Groovy的引擎（对于script task），并且它写道它无法实例化指定的类（对于service task）。如果user task之后有boundary timer，则可以使用。
