Activiti6：调用另外一个文件的流程(把文件当成子流程调用)

1.声明

当前内容主要为本人学习和测试之用，主要内容为一个流程中调用另外一个文件的子流程(主要使用Call Activity)

当前创建pbmn文件使用的是eclipse的activiti插件（例子还是员工请假的例子），安装插件请参考这篇博文：eclipse中安装activit的插件

2.创建流程文件

1.创建主要流程请假主体文件：CallSubProcessEventTest.bpmn

其中调用子流程使用的是：

2.创建另外一个文件：SubProcess.bpmn

3.让主流程文件关联另外一个文件的流程

当前关联主要是通过两个文件的process中的id方式进行关联，并且需要加载两个流程文件才行！

开始配置关联：

此时配置完毕

4.主要测试

import org.activiti.engine.HistoryService;
import org.activiti.engine.ManagementService;
import org.activiti.engine.ProcessEngine;
import org.activiti.engine.ProcessEngineConfiguration;
import org.activiti.engine.RepositoryService;
import org.activiti.engine.RuntimeService;
import org.activiti.engine.TaskService;
import org.activiti.engine.impl.history.HistoryLevel;
import org.activiti.engine.runtime.ProcessInstance;
import org.activiti.engine.task.Task;

public class CallSubProcessEventTest {
    
    
	public static void main(String[] args) {
    
    
		ProcessEngine processEngine = ProcessEngineConfiguration.createStandaloneInMemProcessEngineConfiguration()
				.setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_CREATE_DROP)
				.setJdbcUrl("jdbc:h2:mem:my-own-db;DB_CLOSE_DELAY=1000").setAsyncExecutorActivate(false)
				.setHistoryLevel(HistoryLevel.FULL) // 开启所有历史数据保存的功能，不开启直接查询显示0
				.buildProcessEngine();

		RepositoryService repositoryService = processEngine.getRepositoryService();
		repositoryService.createDeployment().addClasspathResource("\\test\\CallSubProcessEventTest.bpmn")
				.addClasspathResource("\\test\\SubProcess.bpmn").deploy();
		System.out
				.println("Number of process definitions: " + repositoryService.createProcessDefinitionQuery().count());

		TaskService taskService = processEngine.getTaskService();
		RuntimeService runtimeService = processEngine.getRuntimeService();
		HistoryService historyService = processEngine.getHistoryService();
		ManagementService managementService = processEngine.getManagementService();

		ProcessInstance processInstance1 = runtimeService.startProcessInstanceByKey("CallSubProcessEventTest");

		// 1. 填写表单
		Task nextTask = taskService.createTaskQuery().singleResult();
		printTask(nextTask);
		// 完成填写表单的任务
		taskService.complete(nextTask.getId());

		// 2. 直接进入子流程了
		nextTask = taskService.createTaskQuery().singleResult();
		printTask(nextTask);
		processEngine.close();
	}

	public static void printTask(Task task) {
    
    
		System.out.println("当前任务为：" + task.getId() + "," + task.getName());
	}
}

测试结果

测试成功

5.总结

1.以前都是直接在页面上画好子流程，现在可以将子流程分开为特定的文件，然后通过Call Activity方式调用即可，更加层次分明了
