Flowable是一个功能强大的业务流程框架,它使用了Java、Spring Framework、MyBatis和Activiti等技术。通过Flowable,我们可以建模、执行和监控业务流程。下面是一个使用Flowable的示例:
```java
import org.flowable.engine.ProcessEngine;
import org.flowable.engine.ProcessEngineConfiguration;
import org.flowable.engine.RepositoryService;
import org.flowable.engine.RuntimeService;
import org.flowable.engine.TaskService;
import org.flowable.engine.repository.Deployment;
import org.flowable.engine.runtime.ProcessInstance;
import org.flowable.task.api.Task;
public class FlowableExample {
public static void main(String[] args) {
// 创建流程引擎
ProcessEngineConfiguration cfg = ProcessEngineConfiguration.createStandaloneInMemProcessEngineConfiguration();
ProcessEngine processEngine = cfg.buildProcessEngine();
// 部署流程定义
RepositoryService repositoryService = processEngine.getRepositoryService();
Deployment deployment = repositoryService.createDeployment()
.addClasspathResource("my-process.bpmn20.xml")
.deploy();
// 启动流程实例
RuntimeService runtimeService = processEngine.getRuntimeService();
ProcessInstance processInstance = runtimeService.startProcessInstanceByKey("my-process");
// 处理任务
TaskService taskService = processEngine.getTaskService();
Task task = taskService.createTaskQuery().processInstanceId(processInstance.getId()).singleResult();
System.out.println("当前任务:" + task.getName());
// 完成任务
taskService.complete(task.getId());
// 验证流程是否结束
ProcessInstance finishedInstance = runtimeService.createProcessInstanceQuery().processInstanceId(processInstance.getId()).singleResult();
System.out.println("流程是否结束:" + (finishedInstance == null));
// 关闭流程引擎
processEngine.close();
processEngine = null;
}
}
```
这个示例演示了Flowable的基本使用流程,包括创建流程引擎、部署流程定义、启动流程实例、处理任务和验证流程是否结束。你可以根据自己的需求进行进一步的定制和扩展。
