AWS 流程事件开发参考指南

TASK_AFTER_UNDO

任务收回后被触发

常见触发场景

1.已办的下个任务被收回后

2.使用SDK API时

//收回任务
SDK.getTaskAPI().undoTask(taskInstId, uid, undoReason);

开发示例

package com.actionsoft.apps.poc.api.local.process.listener.usertask;

import com.actionsoft.bpms.bpmn.engine.core.delegate.ProcessExecutionContext;
import com.actionsoft.bpms.bpmn.engine.listener.ExecuteListener;
import com.actionsoft.bpms.bpmn.engine.listener.ExecuteListenerInterface;

public class Test_TASK_AFTER_UNDO extends ExecuteListener implements ExecuteListenerInterface {

    public void execute(ProcessExecutionContext ctx) throws Exception {
        info("任务收回后可以补偿被触发-->" + ctx.getTaskInstance());
        // throw new BPMNError("UCode02", "User biz error");
    }

}

此时，ctx.getTaskInstance()获得的任务对象是新的任务实例对象
