例如你要控制對ROOT目錄下文件的訪問：首先更改$TOMCAT_HOME/ROOT/WEB-INF/web.xml
1.在<web-app>和</web-app>之間加入
<security-constraint>
<web-resource-collection>
<web-resource-name>Entire?Application</web-resource-name>
<url-pattern>/*</url-pattern>
</web-resource-collection>
<auth-constraint>
<!--?NOTE:?This?role?is?not?present?in?the?default?users?file?-->
<role-name>user</role-name>
</auth-constraint>
</security-constraint>
<!--?Define?the?Login?Configuration?for?this?Application?-->
<login-config>
<auth-method>BASIC</auth-method>
<realm-name>TEST?ACCESS?CONTROL</realm-name>
</login-config>
2.然后在$TOMCAT_HOME/conf/tomcat-users.xml中加入
<user?name="user"?password="password"?roles="user"/>
roles的名字和web.xml中的相對應(yīng)
在TOMCAT4.03中測試通過?
