在Activiti中使用Java服務(wù)任務(wù)可以通過編寫一個實現(xiàn)了org.activiti.engine.delegate.JavaDelegate接口的Java類來實現(xiàn)。具體步驟如下:
public class MyJavaServiceTask implements JavaDelegate {
@Override
public void execute(DelegateExecution execution) {
// 在這里編寫Java服務(wù)任務(wù)的邏輯
System.out.println("Java服務(wù)任務(wù)執(zhí)行中...");
}
}
<serviceTask id="javaServiceTask" activiti:class="com.example.MyJavaServiceTask" />
RepositoryService repositoryService = processEngine.getRepositoryService();
Deployment deployment = repositoryService.createDeployment()
.addClasspathResource("myProcess.bpmn")
.deploy();
RuntimeService runtimeService = processEngine.getRuntimeService();
ProcessInstance processInstance = runtimeService.startProcessInstanceByKey("myProcess");
通過以上步驟,就可以在Activiti中使用Java服務(wù)任務(wù)了。當(dāng)流程執(zhí)行到Java服務(wù)任務(wù)時,會自動調(diào)用實現(xiàn)的execute方法執(zhí)行相應(yīng)的邏輯。
