Flowable 加签和减签

一：示例

Deployment deploy = repositoryService.createDeployment()
        .name("会签流程")
        .addClasspathResource("processes/CounterSignProcess.bpmn")
        .deploy();

ProcessInstance processInstance = runtimeService.startProcessInstanceByKey("CounterSignProcess");

Map<String, Object> variables = new HashMap<>();
variables.put("list", Arrays.asList("huihui", "monday"));
System.err.println(processInstance.getId());
Task task = taskService.createTaskQuery()
        .processInstanceId(processInstance.getId())
        .singleResult();
taskService.complete(task.getId(), variables);

二：加签

String activityId = "CounterSign";
String processInstanceId = "40005";
Map<String, Object> executionVariables = new HashMap<>();
executionVariables.put("item", "baby");
runtimeService.addMultiInstanceExecution(activityId, processInstanceId, executionVariables);

三：减签

Task task = taskService.createTaskQuery().taskId("40028").singleResult();
String executionId = task.getExecutionId();
runtimeService.deleteMultiInstanceExecution(executionId, false);

act_ru_task 删除一条数据40028。

act_ru_execution 删除了一条40022， 增加了一条45001（不知道为什么要增加）。

减签（二）

Task task = taskService.createTaskQuery().taskId("42505").singleResult();
String executionId = task.getExecutionId();
runtimeService.deleteMultiInstanceExecution(executionId, false);

同样是删除了45001新增了47501。

减签（三）

act_ru_execution: 40023删除，保留了47501，并且新增了50001。

Task task = taskService.createTaskQuery().taskId("40034").singleResult();
String executionId = task.getExecutionId();
// executionIsCompleted : defines if the deleted execution should be marked as completed on the parent multi-instance execution
runtimeService.deleteMultiInstanceExecution(executionId, true);

ACT_HI_TASKINST 中的delete_reason_值为Delete MI execution。
