訪問Tomcat管理器拋出404

這裏是我的tomcat-users.xml中：

<role rolename="manager"/> 
    <role rolename="manager-gui"/> 
    <role rolename="manager-script"/> 
    <role rolename="manager-status"/> 
    <user username="admin" password="tomcat" roles="manager,manager-gui,manager-script,manager-status"/>

這是在server.xml中

<Realm className="org.apache.catalina.realm.MemoryRealm" />

我可以訪問以下網址，服務器領域的片斷：它要求憑據首次]

http://localhost:8080/manager/status http://localhost:8080/manager/status/all

但訪問任何網址：

http://localhost:8080/manager/text/sessions?path=/examples http://localhost:8080/manager/text/serverinfo

失敗，「404未找到」。以下是顯示的錯誤消息：

The page you tried to access (/manager/text/sessions) does not exist. 

The Manager application has been re-structured for Tomcat 7 onwards and some of URLs have changed. All URLs used to access the Manager application should now start with one of the following options: 

/manager/html for the HTML GUI 
/manager/text for the text interface 
/manager/jmxproxy for the JMX proxy 
/manager/status for the status pages 
Note that the URL for the text interface has changed from "/manager" to "/manager/text". 

You probably need to adjust the URL you are using to access the Manager application. However, there is always a chance you have found a bug in the Manager application. If you are sure you have found a bug, and that the bug has not already been reported, please report it to the Apache Tomcat team.

請注意，我正在以/ manager/text訪問URL。即使捲曲失敗，同樣的錯誤。

我是否缺少配置？

許多調試後，我找到了真正的原因是ManagerServlet是未能獲得與以下安全異常實例：

java.lang.SecurityException: Restricted (ContainerServlet) class org.apache.catalina.manager.ManagerServlet

解決的方法是在「上下文設置「特權=真」「部分在TOMCAT_INSTALL_DIR/conf/context.xml中

<!-- The contents of this file will be loaded for each web application --> 
<Context privileged="true"> 

    <!-- Default set of monitored resources. If one of these changes, the --> 
    <!-- web application will be reloaded.
