我的项目中有两个 servlet，第二个是从第一个 servlet 调用的。我在第一个 servlet 中创建 http 会话并为该会话对象设置一些属性。如何在第二个 servlet 中获取这些属性的值？
Thanks in advance.
提前致谢。

Object value = request.getSession().getAttribute("nameOfTheAttributeUsedInTheFirstServlet");
If two servlets are in the same webapp, they share the same session context, and the session is the same for both servlets. Of course, remember that a session is tight to a particular user.
如果两个 servlet 位于同一个 webapp 中，则它们共享相同的会话上下文，并且两个 servlet 的会话相同。当然，请记住，会话对特定用户来说很紧张。
