首先在 tomcat-users.xml中配置css
<tomat-users> <role rolename="Admin"/> <role rolename="Member"/> <role rolename="Guest"/> <user username="Stupid Wolf" password="admin" roles="Admin, Member, Guest"/> </tomcat-users>
接着在 web.xml中配置html
<security-role> <role-name>Admin</role-name> </security-role> <!--受权时,容器将把开发商特定的role信息映射到这里的找到的<role-name>中 -->
定义资源/方法约束web
<security-constraint> <web-resource-collection> <web-resource-name>Resources</web-resource-name> <url-pattern>/url of files</url-pattern> <http-method>POST</http-method> <http-method>GET</http-method> </web-resource-collection> <auth-constraint> <role-name>Admin</role-name> </auth-constraint> </security-constraint>
在web.xml添加tomcat
<login-config> <auth-method>FORM</auth-method> <form-login-config> <form-login-page>/login.html</form-login-page> <form-error-page>/error.html</form-error-page> </form-login-config>
其中login.html error.html的代码分别为jsp
<!DOCTYPE html> <html> <head> <title>login.html</title> <meta name="keywords" content="keyword1,keyword2,keyword3"> <meta name="description" content="this is my page"> <meta name="content-type" content="text/html; charset=UTF-8"> <!--<link rel="stylesheet" type="text/css" href="./styles.css">--> </head> <body> <form name="f1" id="f1" action="j_security_check" method="post"> <table> <tr> <td>Login:</td> <td><input type="text" name="j_username" id="login"></td> </tr> <tr> <td>Password:</td> <td><input type="password" name="j_password" id="password"></td> </tr> <tr> <td colspan="2"><input type="submit"></td> </tr> </table> </form> </body> </html>
<!DOCTYPE html> <html> <head> <title>error.html</title> <meta name="keywords" content="keyword1,keyword2,keyword3"> <meta name="description" content="this is my page"> <meta name="content-type" content="text/html; charset=UTF-8"> <meta charset="UTF-8"> <!--<link rel="stylesheet" type="text/css" href="./styles.css">--> </head> <body> error! 身份认证错误 <br> </body> </html>
最后,咱们也就完成了未经认证的客户请求一个没有传输保证的受限资源
post
附上结果截图:this
其中 Security/test.jsp为一个受限的资源url
当未经受权的用户访问test.jsp时,会弹出一个身份认证的表单spa
输入正确的身份以后,访问成功,不然,访问失败code
