复制代码resource下的spring-security-quickstart.xml配置如下
注：通过配置文件进行登录，而不是数据库。真是项目是要连接数据库

<security:user name="admin" password="{noop}admin"
authorities="ROLE_ADMIN" />
</security:user-service>
</security:authentication-provider>
</security:authentication-manager>
</beans>
复制代码
自定义登录成功或者失败页面
登录页
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
<form action="login" method="post">
<table>
<tr>
<td>用户名：</td>
<td><input type="text" name="username" /></td>
</tr>
<tr>
<td>密码：</td>
<td><input type="password" name="password" /></td>
</tr>
<tr>
<td colspan="2" align="center"><input type="submit" value="登录" />
<input type="reset" value="重置" /></td>
</tr>
</table>
</form>
</body>
</html>
复制代码成功页
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
登陆成功
</body>
</html>
复制代码失败页面
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
用户名或者密码错误
</body>
</html>
