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");
}
