如何在Flowable中执行高效的解部署过程

Question

我怎么才能有效地执行这个。

public void deployResource(String resourceName, InputStream resourceStream, 
    String companyCode) {

    RepositoryService repoService = processEngine.getRepositoryService();
    DeploymentBuilder dbuilder = repoService.createDeployment();
    dbuilder.addInputStream(resourceName, resourceStream);
    dbuilder.name(resourceId);

    if (companyCode != null && !companyCode.isEmpty()) {
        logger.info("Setting Tenant ID with companyCode {}", companyCode);
        dbuilder.tenantId(companyCode);
    }
    dbuilder.deploy();
}

//这是取消部署的方法

 public void undeploy(String resourceName, String companyCode) {
    try {

        logger.debug(LogMarker.ENTRY, "Undeployment Process {} is Started for Resource Name{}", resourceName, companyCode);

        RepositoryService repoService = processEngine.getRepositoryService();

        List<ProcessDefinition> list = repoService.createProcessDefinitionQuery().processDefinitionResourceNameLike(resourceName)
            .processDefinitionTenantIdLike(companyCode).list();

        for (ProcessDefinition processDefinition : list) {
            repoService.deleteDeployment(processDefinition.getDeploymentId(), true);

            logger.debug(LogMarker.EXIT, "Undeployment Process {} is Successfully Completed for Resource Name{}", resourceName);
            break;
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
}

Answer 1

与其查询流程定义，为什么不查询部署？

你可以做：

List<Deployment> deployments = repositoryService.createDeploymentQuery()
    .deploymentTenantId(companyCode)
    .processDefinitionKey(processDefinitionKey)
    .list();

然后可以删除这些部署。请记住，您当前的取消部署方式可能会删除与您的critieria不匹配的流程定义，但这些流程定义是另一个流程定义部署的一部分（您可以在每个部署中部署多个流程定义）。
