用于基于表单的身份验证的Tomcat 7领域配置 [英] Tomcat 7 realm configuration for form based authentication
本文介绍了用于基于表单的身份验证的Tomcat 7领域配置的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我对Java EE还是很陌生，并且刚开始使用tomcat.我正在使用PrimeFaces开发一个小型任务应用程序.
I am quite new to Java EE and was starting out with tomcat. I am developing a small task application with PrimeFaces.
该应用程序具有主页和管理区域，该区域由web.xml文件保护.当我根据此处发布的指南开发登录页面时 http ://docs.oracle.com/cd/E19159-01/819-3669/bncby/index.html .尽管我已经正确配置了领域，但是我无法登录.
The application has a main page and admin area which is protected by the web.xml file. When i develop the login page according to guidelines posted here http://docs.oracle.com/cd/E19159-01/819-3669/bncby/index.html. I cannot login although I have configured the realm properly.
我在>基于tomcat的基于JSP Web应用程序表单的身份验证中阅读了这篇文章这正是我遇到的问题.但是我没有使用Eclipse.
这些是我的编码和XML配置文件.
I read this post on JSP web application form based authentication in tomcat which is exactly the problem I have. But I am not using Eclipse.
These are my codings and XML configuration files.
login.jsp页面
The login.jsp page
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Log In</title>
</head>
<body>
<form method="post" action="j_security_check">
<p>Username</p>
<input type="text" name="j_username" />
<p>Password</p>
<input type="password" name="j_password" />
<p></p>
<input type="submit" value="Submit" /> <input type="reset"
value="reset" />
</form>
</body>
</html>

这是我的tomcat/conf文件夹中的server.xml.
This is my server.xml in tomcat/conf folder.

这是我准备数据库表的方式，数据库称为"todo".
This is how I have prepared the database tables, database is called 'todo'.
mysql> SELECT * FROM users;
+----------+----------+
| username | password |
+----------+----------+
| lal | lal |
| lala | lala |
| mad | mada |
| nalaka | nalaka |
+----------+----------+
4 rows in set (0.00 sec)
mysql> SELECT * FROM user_roles;
+----------+------------+
| username | rolename |
+----------+------------+
| lal | sales |
| lala | management |
| lala | sales |
| mad | admin |
| nalaka | sales |
+----------+------------+
5 rows in set (0.00 sec)
我有，因为在web.xml文件中我已指定为管理员的角色登录到管理区使用的用户狂登录. 当我分别使用用户名和密码mad和mada时，我将重定向到错误页面. URL像这样附加j_security_check.
I have to use user mad to login because in the web.xml file I have specified the role as admin to login to the admin area. When I use the username and password as mad and mada respectively, I get redirected to the error page. And the URL is appended with j_security_check like this.
http://localhost:8081/ToDoApplication/admin/j_security_check
数据库用户tomcat对todo数据库具有SELECT特权. tomcat指南提到，由于tomcat服务器不会写入数据库，因此用户至少必须具有读取权限.
The database user tomcat has SELECT privileges for the todo database. The tomcat guide mentioned that since the tomcat server wont be writing to the database, the user must at least have read privileges.
推荐答案
错误发生在server.xml的"userRolesTable"中，应该是"userRoleTable"
the error was in server.xml's "userRolesTable" it should be "userRoleTable"
