Filter.destroy介绍

[英]Called by the web container to indicate to a filter that it is being taken out of service.

This method is only called once all threads within the filter's doFilter method have exited or after a timeout period has passed. After the web container calls this method, it will not call the doFilter method again on this instance of the filter.

This method gives the filter an opportunity to clean up any resources that are being held (for example, memory, file handles, threads) and make sure that any persistent state is synchronized with the filter's current state in memory.
[中]由web容器调用，以向筛选器指示它正在停止服务。
只有当过滤器的doFilter方法中的所有线程都已退出或超过超时时间后，才会调用此方法。在web容器调用此方法之后，它将不再对筛选器的此实例调用doFilter方法。
此方法使筛选器有机会清理所持有的任何资源（例如，内存、文件句柄、线程），并确保任何持久状态都与内存中筛选器的当前状态同步。
