英文:
Java Spring Application, after HTTP request method
问题
我正在编写一个Java Spring微服务。我的控制器使用@PostMapping。
在HTTP请求完成后，我希望自动调用清理方法。这可能吗？
原因是我的应用程序可能会从不同的地方抛出异常，如果我有一个单独的方法在请求完成后被调用，那么我只需要在一个地方编写我的清理例程，而不用担心在服务中的新流程中遗漏清理代码。
英文:
I a writing a Java Spring Microservice. My controller uses @PostMapping
After a HTTP request to my controller completes I would like to automatically call a cleanup method. Is this possible?
Reason is my app can throw from different places and if I had one single method that gets called after the request completes then I can just write my cleanup routine in one place and not worry about leaving out cleanup code from new flows in the service.

你可以创建一个实现了 HandlerInterceptor 接口的类，然后重写 postHandle 或者 afterCompletion 方法。
英文:
You can have a class which implements HandlerInterceptor and then over-ride postHandle or afterCompletion
