tomcat session共享

一      tomcat 本身session复制共享方法

我们打开conf下的server.xml文件，找到下面这一行：

 <Engine name="Catalina" defaultHost="localhost">

在后面添加 下面1或者2 中的内容，为什么有2个？，因为 tomcat 的版本不同，可能有的类后面的版本就没了。

我的8.4，27  用的第二种。

然后在项目里面的web.xml 中添加<distributable/>

有提示 奇怪的ip端口被占用 ？

将<Receiver className="org.apache.catalina.tribes.transport.nio.NioReceiver"
address="auto"

将auto改为ip就好了。
