Activiti:如何创建自定义事件并进行监听？

import org.activiti.engine.delegate.event.ActivitiEvent;
import org.activiti.engine.delegate.event.ActivitiEventListener;

public class CustomEventListener implements ActivitiEventListener {

    @Override
    public void onEvent(ActivitiEvent event) {
        // 处理自定义事件的逻辑
        if (event.getType().equals("customEvent")) {
            // 执行自定义事件的处理逻辑
            System.out.println("Custom event occurred: " + event.getProcessInstanceId());
        }
    }

    @Override
    public boolean isFailOnException() {
        return false;
    }
}

import org.activiti.engine.ProcessEngine;
import org.activiti.engine.ProcessEngineConfiguration;
import org.activiti.engine.delegate.event.ActivitiEventType;

public class CustomEventExample {

    public static void main(String[] args) {
        // 创建流程引擎配置对象
        ProcessEngineConfiguration configuration = ProcessEngineConfiguration.createStandaloneProcessEngineConfiguration();
        // 配置数据库连接等信息
        // ...

        // 注册自定义事件监听器
        configuration.setEventListeners(Arrays.asList(new CustomEventListener()));

        // 创建流程引擎
        ProcessEngine processEngine = configuration.buildProcessEngine();

        // 发布自定义事件
        processEngine.getRuntimeService().addEventListener(new CustomEvent());

        // 执行工作流程
        // ...
    }
}
