1.3.5.4.1. 流程事件监听

事件监听文档见 apidoc 的 com.seeyon.ctp.event.Event。 因为使用页面发起的流程第三方系统无法获取协同 ID，所以事件监听主要适用于使用代码发起的模板协同。 目前支持以下的事件监听：

事件名称 事件类 备注
流程发起事件 com.seeyon.apps.collaboration.event.CollaborationStartEvent 发起协同、直接发送、转发、移动应用发送、平台接口发起协同均触发此事件
流程处理事件 com.seeyon.apps.collaboration.event.CollaborationProcessEvent  
流程结束事件 com.seeyon.apps.collaboration.event.CollaborationFinishEvent  
流程撤销事件 com.seeyon.apps.collaboration.event.CollaborationCancelEvent  
流程回退事件 com.seeyon.apps.collaboration.event.CollaborationStepBackEvent  
流程终止事件 com.seeyon.apps.collaboration.event.CollaborationStopEvent  

示例：

    @ListenEvent(event = CollaborationProcessEvent.class, async = true)
    public void onProcess(CollaborationProcessEvent event) {
        System.out.println("处理");
        try {
            System.out.println("我的affairId：" + event.getAffairId());
            System.out.println("模板编号：" + event.getTemplateCode());
            System.out.println("已完成？" + event.isFinished());
            System.out.println("已终止？" + event.isTerminated());

            if (event.isTemplate("F0001") && event.isVouched()) {
                System.out.println("F0001模板核定通过");
            }
            // 与3.5的CollaborationFormApprovalEvent作用相同
            if (event.isTemplate("F0001") && event.isFormAudited()) {
                System.out.println("F0001模板表单审核通过");
            }
        } catch (BusinessException e) {
            System.err.println(e.getLocalizedMessage());
        }
    }

    @ListenEvent(event = CollaborationStartEvent.class, async = true)
    public void onStart(CollaborationStartEvent event) throws BusinessException {
            System.out.println("发起，我开动了");
            System.out.println("我的affairId：" + event.getAffairId());
            System.out.println("PC、手机或是接口发起的？" + event.getFrom());
    }

    @ListenEvent(event = CollaborationStopEvent.class, async = true)
    public void onStop(CollaborationStopEvent event) {
        System.out.println("终止");
        try {
            System.out.println("谁终止了我：" + event.getUserId());
            System.out.println("模板编号：" + event.getTemplateCode());
        } catch (BusinessException e) {
            System.err.println(e.getLocalizedMessage());
        }
    }

    @ListenEvent(event = CollaborationStepBackEvent.class, async = true)
    public void onStepBack(CollaborationStepBackEvent event) {
        System.out.println("回退");
        try {
            System.out.println("模板编号：" + event.getTemplateCode());
        } catch (BusinessException e) {
            System.err.println(e.getLocalizedMessage());
        }
    }

    @ListenEvent(event = CollaborationFinishEvent.class, async = true)
    public void onFinish(CollaborationFinishEvent event) {
        System.out.println("完成，我先到达终点:)");
        try {
            System.out.println("我的affairId：" + event.getAffairId());
            System.out.println("模板编号：" + event.getTemplateCode());
        } catch (BusinessException e) {
            System.err.println(e.getLocalizedMessage());
        }
    }

    @ListenEvent(event = CollaborationCancelEvent.class, async = true)
    public void onCancel(CollaborationCancelEvent event) {
        System.out.println("被撤销了...:(");
        try {
            System.out.println("我记得你，是你撤销的：" + event.getUserId());
            System.out.println("为什么撤销？" + event.getMessage());
            System.out.println("模板编号：" + event.getTemplateCode());
        } catch (BusinessException e) {
            System.err.println(e.getLocalizedMessage());
        }
    }
