在前面三个博客的例子中,登录页面都是用的Spring Security本身提供的,这明显不符合实际开发场景,同时也没有退出和注销按钮,所以在每次测试的时候都要经过关闭浏览器来注销达到清除session的效果。html
login.jsp:java
<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>自定义登录页面</title>
</head>
<body>
<div class="error ${param.error == true ? '' : 'hide'}">
登录失败<br>
${sessionScope['SPRING_SECURITY_LAST_EXCEPTION'].message}
</div>
<form method="post" action="${pageContext.request.contextPath}/j_spring_security_check" style="width:260px; text-align: center">
<fieldset>
<legend>登录</legend>
用户: <input type="text" name="j_username" style="width: 150px;"
value="${sessionScope['SPRING_SECURITY_LAST_USERNAME']}" /><br />
密码: <input type="password" name="j_password" style="width: 150px;" /><br />
<input type="checkbox" name="_spring_security_remember_me" />两周以内没必要登录<br />
<input type="submit" value="登录" /> <input type="reset" value="重置" />
</fieldset>
</form>
</body>
</html>复制代码
说明:特别要注意的是form表单的action是提交登录信息的地址,这是security内部定义好的,同时自定义form时,要把form的action设置为/jspringsecurity_check。注意这里要使用绝对路径,避免登录页面存放的页面可能带来的问题。jusername,输入登录名的参数名称,jpassword,输入密码的参数名称,这两个正常状况下也不会修改。mysql
springsecurityrememberme,选择是否容许自动登陆的参数名称。能够直接把这个参数设置为一个checkbox,无需设置value,Spring Security会自行判断它是否被选中,这也是security内部提供的,只须要配置,不须要本身实现。spring

这里定义了两个页面,index.jsp用户和管理员均可以访问,adminPage.jsp只有管理员能够访问,同时两个页面都有注销按钮,注销按钮提交的地址也就是上面配置文件中的地址/jspringsecurity_logout。pom.xml和前面的同样,这里就不贴了。jsp
当输入普通用户的用户名和密码,同时勾选2周不用登录后,由于adminPage.jsp页面要有管理员权限才能访问,因此普通用户访问失败,index.jsp页面就能够访问;这时关闭页面后,再次访问资源,由于勾选了2周不用登录,因此能够成功访问;可是当点击退出登陆后,再次访问是就会跳转到登录页面,要求登录才能访问。
当输入管理员名和密码,同时勾选2周不用登录,验证成功后,跳转到index.jsp,同时adminPage.jsp也能够访问,这时把一个页面关闭再从新访问资源时,由于勾选2周不用登录,因此能够成功访问;而后注销,这是再访问资源时,就会跳转到登录页面,要求登录才能访问。微信公众号关注:ByteZ,获取更多学习资料
