如何配置tomcat-users.xml来保护tomcat中的页面？

可能回答晚了，但是无论如何您都在web.xml中缺少角色，也不必提及领域，因此您的web.xml应该如下所示

<security-constraint>   <web-resource-collection>      <web-resource-name>Admin</web-resource-name>      <url-pattern>/admin/*</url-pattern>    </web-resource-collection>    <auth-constraint>      <role-name>admin</role-name>    </auth-constraint> </security-constraint> <login-config>       <auth-method>BASIC</auth-method>      <!-- Please note following line .. its commented -->      <!-- <realm-name>Admin</realm-name> --> </login-config> <!-- Following section was missing --> <security-role>     <role-name>admin</role-name></security-role>
