Question

我在执行时遇到异常no processes deployed with key 'Process_MohitWorkflow'：

ProcessInstance instance =
runtimeService.startProcessInstanceByKey(workflowName, businessKey, variables);

我的act_re_procdef表格中有一个关于此工作流程的条目

＆＃34; Process_MohitWorkflow：1：14＆＃34 ;; 1;＆＃34; http://www.activiti.org/processdef＆＃34 ;;＆＃34;莫希特信任＆＃34 ;;＆＃34; Process_MohitWorkflow＆＃34 ;; 1;＆＃34; 11＆＃34 ;;＆＃34; MyBPMN.bpmn20.xml＆＃34 ;;＆＃34; MyBPMN.Process_MohitWorkflow.png＆＃34; ;＆＃34;＆＃34 ;; FALSE; TRUE; 1;＆＃34; 603＆＃34;

我使用以下代码部署了MyBPMN.bpmn20.xml文件：

      public void deployProcessFile(String name, InputStream io, long tenantId) {
        RepositoryService repositoryService = processEngine.getRepositoryService();
        repositoryService.createDeployment()
                .addInputStream(name, io)
                .name(name.substring(0, name.indexOf(".")))
                .enableDuplicateFiltering()
                .tenantId(String.valueOf(tenantId))
                .deploy();
      }

堆栈跟踪：

对我可能缺少什么的想法？

问候。

Answer 1

我设法通过使用：

解决了这个问题

ProcessInstance instance = runtimeService.startProcessInstanceByKey(
  workflowName, businessKey, variables, tenantId);

而不是：

ProcessInstance instance = runtimeService.startProcessInstanceByKey(
  workflowName, businessKey, variables);

最初，我只依靠：

processEngine.getRepositoryService().createProcessDefinitionQuery() .processDefinitionTenantId(tenantId) .singleResult()

过滤掉基于tenantId的进程，但我认为这还不够。

不确定这是如何工作的（为什么我们必须提供额外的参数，即tenantId到startProcessInstance）或者在发布之前我应该做些什么才能看到这个。

您可能无法使用RuntimeService::startProcessInstanceById()启动流程的另一个原因是，作为该方法的输入所需的id与xml文件中的id属性不同。 Activiti则将后者称为密钥。

RuntimeService::startProcessInstanceById()期望Activiti引擎在部署时生成的字符串ID。生成的ID的格式为key:version。

Answer 3

尝试将子进程与原始进程一起部署：

 repositoryService.createDeployment()
                .addClasspathResource("diagrams/Process.bpmn")
                .deploy();

 repositoryService.createDeployment()
                .addClasspathResource("diagrams/Process_Subprocess.bpmn")
                .deploy();

我在junit中这样做，现在正在工作。

Activiti：没有使用密钥部署的进程
