activiti部署后怎么删除，代码演示

在Activiti引擎中，部署流程定义通常是通过`Deployment`对象来进行的。一旦部署完成，你可以使用`RepositoryService`提供的`deleteDeployment()`方法来删除它。这里是一个简单的Java代码示例：

import org.activiti.engine.RepositoryService;
import org.activiti.engine.repository.Deployment;

// 假设你已经注入了RepositoryService
RepositoryService repositoryService = ...;

// 获取部署ID，这通常来自于任务或其他业务处理
String deploymentId = "your-deployment-id";

// 删除部署
if (repositoryService.createDeploymentQuery().deploymentId(deploymentId).singleResult() != null) {
    Deployment deployment = repositoryService.createDeploymentQuery().deploymentId(deploymentId).singleResult();
    repositoryService.deleteDeployment(deployment.getId(), true); // 第二个参数true表示强制删除，如果流程实例还在运行则需要关闭它们
    System.out.println("Deployment with id " + deploymentId + " has been deleted.");
} else {
    System.err.println("Deployment not found with id " + deploymentId);
}
