Security Tomcat内存不工作

我创建了一个web应用程序，并配置了tomcat容器，以使用tomcat内存领域对用户进行身份验证。但它不起作用。下面是我的配置文件

Web.xml

请检查一下这个配置有什么问题。当我打开下面的链接

http://localhost:8080/eMedicalBookingServer/index.html

它不会提示输入用户凭据

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

<tomcat-users>
<role rolename="tomcat"/>
<role rolename="role1"/>
<role rolename="admin"/>
<role rolename="superuser"/>
<user username="tomcat" password="tomcat" roles="tomcat"/>
<user username="both" password="tomcat" roles="tomcat,role1"/>
<user username="role1" password="tomcat" roles="role1"/>
<user username="ars" password="pass" roles="superuser"/>
<user username="ad1" password="pass" roles="admin"/>
</tomcat-users>
