流程分支、聚合。流程每个分支节点都全部处理完成后，聚合到下一个节点。

流程操作代码
//流程部署
public void deploy()
{
super.startUp();
repositoryService.createDeployment().addResourceFromClasspath("com/tgb/node/fork/fork.jpdl.xml").deploy();
}
//创建流程实例
public void createInstance()
{
super.startUp();
ProcessInstance processInstance =
executionService.startProcessInstanceByKey("fork");
print("流程实例ID",processInstance.getId());
}
获取当前节点
public void getCurrectActivity()
{
super.startUp();
String name =
executionService.createProcessInstanceQuery().processInstanceId("fork.10001").uniqueResult().findActiveActivityNames().toString();
print("当前节点",name);
}
//获取任务列表
public void getTask()
{
super.startUp();
List<Task> tasks =
taskService.findPersonalTasks("userM");
print("任务节点名称",tasks.get(0).getActivityName());
print("任务节点ID",tasks.get(0).getId());
}
//完成任务
public void completeTask()
{
super.startUp();
taskService.completeTask("20001");
}
