import org.activiti.engine.ProcessEngine;
import org.activiti.engine.ProcessEngines;
import org.activiti.engine.RuntimeService;
import org.activiti.engine.repository.Deployment;
import org.activiti.engine.runtime.ProcessInstance;
import org.junit.Test;

public class HelloWorld {

ProcessEngine pe = ProcessEngines.getDefaultProcessEngine();
/**流程部署 */
@Test
public void deploymentProcessDefinition(){
Deployment deployment = pe.getRepositoryService() //流程定义和部署相关的service
.createDeployment() //创建一个部署对象
.addClasspathResource("diagrams/helloworld.bpmn")
.addClasspathResource("diagrams/helloworld.png")
.name("请假流程")
.deploy();
System.out.println("部署流程ID: "+deployment.getId());
System.out.println("类别: "+deployment.getCategory());
System.out.println("名称: "+deployment.getName());
System.out.println("房客: "+deployment.getTenantId());
System.out.println("部署流程entity: "+deployment.getClass());
System.out.println("部署流程时间: "+deployment.getDeploymentTime());
}

/**启动流程实例 */
@Test
public void startProcessInstance(){ //启动工作流

String processDefinitionKey = "helloworld";
RuntimeService runtimeService = pe.getRuntimeService();
ProcessInstance processInstance = runtimeService //与正在执行的流程和执行相关对象的service
.startProcessInstanceByKey(processDefinitionKey);//根据流程定义的key启动流程实例,key对象bpmn文件中id属性的值
System.out.println("流程实例ID: "+processInstance.getId());
System.out.println("流程定义ID: "+processInstance.getProcessInstanceId());
}

}
上面是相关代码，流程部署方法是可以运行的，启动流程实例到了 runtimeService .startProcessInstanceByKey(processDefinitionKey)就报错了，错误信息如下：
