10个客户端请求Servlet。如何创建多个servlet实例 [英] 10 clients requests for a Servlet.How many servlet instances are created

问题描述

假设有10个客户端请求Servlet。创建了多少个servlet实例？如果每个实例都试图进行更改，它还会创建任何并发修改问题吗？请帮助。

Suppose 10 clients requests for a Servlet. How many servlet instances are created? Also will it create any concurrency modification problem if each instance is trying to make changes? Please help.

推荐答案

只存在一个servlet实例（每个类加载器），每个请求将在自己的线程上提供

Only one instance of servlet exist (per classloader) , and each request will be served on its own thread

因此，您需要管理同步的请求之间是否有任何共享

So is there any thing that is shared amongst requests you need to manage synchronization
