【入门篇】Activiti流程部署两种方法

需求

  将绘制好的工作流程图，进行部署定义，这里有两种方法

首先创建processEngine

 

//创建processEngine
	private ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();

 

方法一：

单个文件部署流程，直接操作绘制好的bpmn和png文件资源，代码如下：

 

public void deployment(){
		//使用RespositoryService
		RepositoryService repositoryService = processEngine.getRepositoryService();
		//部署bpmn文件和png文件
		//bpmn文件名
		String resourceName_bpmn = "purchasingflow01.bpmn";
		InputStream inputStream_bpmn = this.getClass().getClassLoader().getResourceAsStream("diagram/purchasingflow01.bpmn");
		
		//bpmn文件名
		String resourceName_png = "purchasingflow01.png";
		InputStream inputStream_png = this.getClass().getClassLoader().getResourceAsStream("diagram/purchasingflow01.png");
		
		//部署对象
		Deployment deployment = repositoryService.createDeployment()
				.addInputStream(resourceName_bpmn, inputStream_bpmn)//部署bpmn
				.addInputStream(resourceName_png, inputStream_png)//部署png
				.deploy();
		//部署id
		System.out.println("部署id："+deployment.getId());
		System.out.println("部署时间：" + deployment.getDeploymentTime());
	}

 

方法二：

压缩包部署方法，将绘制好的bpmn和png资源压缩为zip，后期部署的时候，直接读取zip文件完成流程部署，代码如下：

 

public void deployProcessByZip(){
		//定义zip输入流
		InputStream inputStream = this
				.getClass()
				.getClassLoader()
				.getResourceAsStream("cn/itcast/activiti/first/purchasingflow.zip");
		ZipInputStream zipInputStream = new ZipInputStream(inputStream);
		//获取repositoryService
		RepositoryService repositoryService = processEngine
				.getRepositoryService();
		//流程部署
		Deployment deployment = repositoryService.createDeployment()
				.addZipInputStream(zipInputStream)
				.deploy();
		System.out.println("流程部署id：" + deployment.getId());
		System.out.println("流程部署名称：" + deployment.getName());
		
	}

本人工程文件资源和java类目录结构如下：
