用activiti做流程引擎時，我們需要定製一些全域性配置，如主鍵的生成規則，全域性事件等。
在activiti5中，是這樣實現的

    @Bean(name = "processEngineConfiguration")
    public ProcessEngineConfigurationImpl processEngineConfiguration() {
        SpringProcessEngineConfiguration processEngineConfiguration = new SpringProcessEngineConfiguration();
        processEngineConfiguration.setDataSource(druidDataSource());
        processEngineConfiguration.setTransactionManager(annotationDrivenTransactionManager());
        //設定全域性事件監聽
        processEngineConfiguration.setTypedEventListeners(this.getGlobalActivitiEventListener());
        //重寫節點行為
        processEngineConfiguration.setActivityBehaviorFactory(new ActivityBehaviorFactory());
        //設定主鍵生成
        processEngineConfiguration.setIdGenerator(new ActivitiIdGenerator());
        //設定函式
        processEngineConfiguration.setBeans(FunctionFactory.getFunctionBeans());
        return processEngineConfiguration;
    }
 

但是這樣的程式碼，在flowable不起作用。經分析，調整程式碼如下：

@Bean
    public EngineConfigurationConfigurer<SpringProcessEngineConfiguration> customIdGeneratorConfigurer() {
        return engineConfiguration -> {engineConfiguration.setIdGenerator( customIdGenerator());
            engineConfiguration.setActivityBehaviorFactory(activityBehaviorFactory());
            engineConfiguration.setTransactionManager(transactionManager);
        };
    }
 

經測試，功能OK!
