J2EE安全之Http基本验证

http基本验证也是常用保障j2ee程序安全的重要验证方式之一.

下面小结一下.

以tomcat的admin角色为例.

tomcat-users.xml代码如下:

1. <?xml version='1.0' encoding='utf-8'?>
2. <tomcat-users>
3.   <role rolename="tomcat"/>
4.   <role rolename="role1"/>
5.   <role rolename="manager"/>
6.   <role rolename="admin"/>
7.   <user username="tomcat" password="tomcat" roles="tomcat"/>
8.   <user username="role1" password="tomcat" roles="role1"/>
9.   <user username="both" password="tomcat" roles="tomcat,role1"/>
10.   <user username="admin" password="admin" roles="admin,manager"/>
11. </tomcat-users>

若想将web项目中的/root目录下的资源只对admin角色开放.可如下配置项目的web.xml文件

1. <security-constraint>
2.     <web-resource-collection>
3.         <web-resource-name>zgx</web-resource-name>
4.         <url-pattern>/root/*</url-pattern>
5.         <http-method>POST</http-method>
6.         <http-method>GET</http-method>
7.     </web-resource-collection>
8.     <auth-constraint>
9.         <role-name>admin</role-name>
10.     </auth-constraint>
11.     <user-data-constraint>
12.         <transport-guarantee>NONE</transport-guarantee>
13.     </user-data-constraint>
14.   </security-constraint>
15.   <security-role>
16.     <role-name>admin</role-name>
17.   </security-role>
18.   <login-config>
19.     <auth-method>BASIC</auth-method>
20.     <realm-name>zgx</realm-name>
21.   </login-config>

 

这样,访问/root目录下的文件时,需要提供admin用户名和密码.
