我正在关注Tomcat 7的一本书，并且我试图将PersistentManager与FileStore一起用于会话持久性。尝试在Tomcat中使用PersistentManager时获取404错误
我有一个Tomcat 7服务器在Eclipse中运行，所以我去了它的文件夹中的项目资源管理器和位于那里的context.xml文件我插入下面的文本
<Manager>
className="org.apache.catalina.session.PersistentManager"
saveOnRestart="true"
maxActiveSessions="-1"
minIdleSwap="-1"
maxIdleSwap="-1"
maxIdleBackup="-1"
<Store className="org.apache.catalina.session.FileStore" directory="/mypath/mydir" />
</Manager>
正如书上说我必须将Manager设置在context.xml文件中，并且当我通过Eclipse运行Tomcat时，我认为这是要使用的context.xml文件。无论如何，当我插入该文本并重新启动Tomcat，当我尝试访问我的本地主机网页时，我得到了一个404。当我点击重新启动时，以下是控制台的输出 -
