1. 串行的回退
我们先从最简单的串行流程来分析，案例如下

上面的流程就是一个非常简单的串行任务，定义了 4 个用户任务，指派的处理人分别是user1,user2,user3,user4. 在流程的执行过程中我们可以通过回退来演示具体的效果。首先来部署流程
/**
* 部署流程
*/
@Test
void testDeploy() throws Exception {
Deployment deploy = repositoryService.createDeployment()
.addClasspathResource("任务回退01.bpmn20.xml")
.name("任务回退01")
.deploy();
System.out.println("deploy.getId() = " + deploy.getId());
System.out.println("deploy.getName() = " + deploy.getName());
System.out.println("部署开始的时间：" + new Date());
//TimeUnit.MINUTES.sleep(3);
}
然后我们启动一个流程实例。
/**
* 启动流程实例
*/
@Test
void startProcess(){
ProcessInstance processInstance = runtimeService
.startProcessInstanceById("myProcess:1:4");
System.out.println("processInstance.getId() = " + processInstance.getId());
}
然后我们通过 user1 完成任务，直到 user3 完成任务，到 user4 来处理任务。
/**
* 完成任务
*/
@Test
void completeTask(){
Task task = taskService.createTaskQuery()
.processDefinitionId("myProcess:1:4")
.taskAssignee("user1")
.singleResult();
taskService.complete(task.getId());
}
通过上面的多个 Task 完成操作，现在已经到了 user4 来处理的节点了
我们先看下从用户任务4回退到用户任务3的操作。
/**
* 回退操作
*/
@Test
void rollbackTask(){
// 当前的Task对应的用户任务的Id
List<String> currentActivityIds = new ArrayList<>();
currentActivityIds.add("usertask4");
// 需要回退的目标节点的用户任务Id
String newActivityId = "usertask3";
// 回退操作
runtimeService.createChangeActivityStateBuilder()
.processInstanceId("2501")
.moveActivityIdsToSingleActivityId(currentActivityIds,newActivityId)
.changeState();
}
操作后我们可以在对应的历史表中看到相关的信息
然后我们通过 user3 来完成任务继续到 user4 处理，然后我们可以测试回退到 user1 处。
/**
* 回退操作
*/
@Test
void rollbackTask(){
// 当前的Task对应的用户任务的Id
List<String> currentActivityIds = new ArrayList<>();
currentActivityIds.add("usertask4");
// 需要回退的目标节点的用户任务Id
String newActivityId = "usertask1";
// 回退操作
runtimeService.createChangeActivityStateBuilder()
.processInstanceId("2501")
.moveActivityIdsToSingleActivityId(currentActivityIds,newActivityId)
.changeState();
}
可以看到任务又回到了 user1 处。也就是在串行的流程中，我们可以回退到任意的用户节点，当然这个串行也包括多人会签和排他网关节点。当然在回退的时候我们还可以使用moveActivityIdTo(String currentActivityId,String newActivityId)这个方法来处理。
2. 并行的回退
接下来我们在并行的场景中来看看各种回退的场景。具体案例流程如下：

先部署流程，然后启动并运行到并行流程的节点如下的位置
然后我们可以尝试从业务副总处回退到用户审批01处，看看该处理应该要如何实现。
回退逻辑代码的实现
/**
* 回退操作
* 业务副总驳回到到用户审批处 那么行政审批的也应该要返回
*/
@Test
void rollbackTask(){
// 当前的Task对应的用户任务的Id
List<String> currentActivityIds = new ArrayList<>();
currentActivityIds.add("usertask4"); // 行政副总
currentActivityIds.add("usertask3"); // 业务副总
// 需要回退的目标节点的用户任务Id
String newActivityId = "usertask1"; // 用户审批01
// 回退操作
runtimeService.createChangeActivityStateBuilder()
.processInstanceId("22501")
.moveActivityIdsToSingleActivityId(currentActivityIds,newActivityId)
.changeState();
}
查看 ACT_RU_TASK 可以看到回到了用户审批01了
同时在 ACT_HI_ACTINS 中也可以看到回退的历史操作
然后再来看看 行政副总的 并行分支执行完成了，然后在 业务副总处审批要驳回的处理
@Test
void rollbackTask(){
// 当前的Task对应的用户任务的Id
List<String> currentActivityIds = new ArrayList<>();
currentActivityIds.add("usertask4"); // 行政副总
//currentActivityIds.add("usertask3"); // 业务副总
// 需要回退的目标节点的用户任务Id
String newActivityId = "usertask1"; // 用户审批01
// 回退操作
runtimeService.createChangeActivityStateBuilder()
.processInstanceId("22501")
.moveActivityIdsToSingleActivityId(currentActivityIds,newActivityId)
.changeState();
}
一样的效果
3. 子流程回退
最后我们来看看带有子流程的场景下如果有回退的情况应该要如何来处理, 案例如下：

部署流程后并启动流程，我们先来看第一个场景，从子流程回退到主流程，也就是如下图：
Task 进入到了子流程的 Task 处
然后我们来处理回退到主流程: 直接跳转即可
/**
* 回退操作
* 从子流程回退到主流程操作
*/
@Test
void rollbackMainTask(){
// 回退操作
runtimeService.createChangeActivityStateBuilder()
.processInstanceId("2501")
.moveActivityIdTo("usertask2","usertask1")
.changeState();
}
}
/**
* 回退操作
* 从子流程回退到主流程操作：moveExecutionToActivityId不关心当前的节点
*/
@Test
void rollbackMainTask(){
// 回退操作
runtimeService.createChangeActivityStateBuilder()
.processInstanceId("2501")
.moveExecutionToActivityId("5003","usertask1")
.changeState();
}
然后从主流程回退到子流程操作
同样的直接跳转即可
/**
* 回退操作
*/
@Test
void rollbackSubTask(){
// 回退操作
runtimeService.createChangeActivityStateBuilder()
.processInstanceId("2501")
.moveActivityIdTo("usertask3","usertask2")
.changeState();
}
