创建springboot项目
创建一个springboot项目引入相关的依赖,引入activiti 需要的相关依赖。

idea 上安装activiti 插件
可以参考这篇文章：安装activiti 插件
使用的效果如图：

生成的文件是以bpmn结尾，同时我们可以把bpmn文件转化成xml 文件，生成的xml文件如下：

启动一个简单的流程
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT, classes = Application.class)
public class VeryProcessTest {
ProcessEngine processEngine;
@Before
public void testBefore() {
// 创建流程引擎
processEngine = ProcessEngineConfiguration.createStandaloneInMemProcessEngineConfiguration()
.buildProcessEngine();
}
@Test
public void test() {
//部署流程定义文件
RepositoryService repositoryService = processEngine.getRepositoryService();
Deployment deploy = processEngine.getRepositoryService()
.createDeployment()
.addClasspathResource("leave.bpmn")
.deploy();
assertNotNull(deploy);
RuntimeService runtimeService = processEngine.getRuntimeService();
//创建流程定义
ProcessDefinition processDefinition = repositoryService.createProcessDefinitionQuery().deploymentId(
deploy.getId()).singleResult();
//初始化流程
ProcessInstance processInstance = runtimeService.startProcessInstanceByKey(processDefinition.getKey());
assertNotNull(processInstance);
}
}
- 需要注意的是这里使用的是内存数据库，可以参考pom依赖文件。
- 需要注意activiti 部署流程资源有很多种方式，可以选择你比较喜欢的。
流程部署方式
创建一个流程的步骤是：
获取流程引擎(ProcessEngine)-->部署流程定义文件-->创建流程定义--->初始化具体流程
