【JBPM4】流程分支fork - join

流程分支、聚合。流程每一個分支節點都所有處理完成後，聚合到下一個節點。

流程操做代碼

//流程部署
public void deploy() {
super.startUp();
repositoryService.createDeployment().addResourceFromClasspath("com/tgb/node/fork/fork.jpdl.xml").deploy();

}

//建立流程實例
public void createInstance() {
super.startUp();
ProcessInstance processInstance = executionService.startProcessInstanceByKey("fork");
print("流程實例ID",processInstance.getId());
}

獲取當前節點
public void getCurrectActivity() {
super.startUp();
String name = executionService.createProcessInstanceQuery().processInstanceId("fork.10001").uniqueResult().findActiveActivityNames().toString();
print("當前節點",name);
}

//獲取任務列表
public void getTask() {
super.startUp();
List<Task> tasks = taskService.findPersonalTasks("userM");
print("任務節點名稱",tasks.get(0).getActivityName());
print("任務節點ID",tasks.get(0).getId());
}

//完成任務
public void completeTask() {
super.startUp();
taskService.completeTask("20001");
}
