servlet 生命周期和过滤器生命周期之间的区别 [英] difference between servlet lifecycle and filter lifecycle

问题描述

servlet 和过滤器生命周期之间有什么区别吗?.

is there any difference between servlet and filter lifecycle?.

推荐答案

不，一个 servlet 和一个过滤器:

No, both a servlet and a filter:

• 在上下文开始时实例化(一次)
• init(..) 方法被调用
• 他们处理每个请求 - 首先它通过所有过滤器，然后到达 servlet
• 当上下文被销毁时(即当您的容器停止时，或者您的应用程序从管理器控制台取消部署时)，destroy(..) 方法被调用

• are instantiated (once) when the context starts
• the init(..) method is called
• they handle each request - first it passes through all filters and then reaches the servlet
• when the context is destroyed (i.e. when your container stops, or your application is undeployed from the manager console), the destroy(..) method is called
