启动Activiti项目报错：org.activiti.engine.ActivitiObjectNotFoundException: no deployed process definition found with id '22501'

背景

• 启动activiti项目时，出现错误org.activiti.engine.ActivitiObjectNotFoundException: no deployed process definition found with id '22501'

原因

• 获取流程实例信息时，创建查询语句不正确
• 下面是出错的代码

        //获取进程方法
        RepositoryService repositoryService = processEngine.getRepositoryService();
        RuntimeService runtimeService = processEngine.getRuntimeService1
        //部署流程
        DeploymentBuilder createDeployment = repositoryService.createDeployment();
        DeploymentBuilder addClasspathResource = createDeployment.addClasspathResource("diagrams/Vacation.bpmn");
        Deployment deploy = addClasspathResource.deploy();
        //获取流程实例信息
        DeploymentQuery createDeploymentQuery = repositoryService.createDeploymentQuery();
        DeploymentQuery deploymentId = createDeploymentQuery.deploymentId(deploy.getId());

        Deployment singleResult = deploymentId.singleResult();
        //流程开始
        Map<String, Object> vars = new HashMap<String, Object>();
        vars.put("employeeName", "jingguoliang");
        vars.put("numberOfDays", new Integer(4));
        vars.put("VocationMotivation", "I will play with my friendgird");
        ProcessInstance startProcessInstanceById = runtimeService.startProcessInstanceById(singleResult.getId(), vars);            

• 下面是正确的代码

    　　//获取进程方法
        RepositoryService repositoryService = processEngine.getRepositoryService();
        RuntimeService runtimeService = processEngine.getRuntimeService();

        //定义流程
        DeploymentBuilder createDeployment = repositoryService.createDeployment();
        DeploymentBuilder addClasspathResource = createDeployment.addClasspathResource("diagrams/Vacation.bpmn");
        Deployment deploy = addClasspathResource.deploy();

        //获取流程实例信息
        ProcessDefinitionQuery createProcessDefinitionQuery = repositoryService.createProcessDefinitionQuery();
        ProcessDefinitionQuery deploymentId = createProcessDefinitionQuery.deploymentId(deploy.getId());

        ProcessDefinition singleResult = deploymentId.singleResult();

        //流程开始
        Map<String, Object> vars = new HashMap<String, Object>();
        vars.put("employeeName", "jingguoliang");
        vars.put("numberOfDays", new Integer(4));
        vars.put("VocationMotivation", "I will play with my friendgird");
        ProcessInstance startProcessInstanceById = runtimeService.startProcessInstanceById(singleResult.getId(), vars);
