spring security采用自定义登录页和退出功能
更新。。。
首先采用的是XML配置方式,请先查看 初识Spring security-添加security 在之前的示例中进行代码修改
项目结构如下:
一、修改spring-security.xml文件,添加配置如下
<security:http auto-config="true"> <security:intercept-url pattern="/admin**" access="hasRole('ROLE_USER')"/> <security:form-login login-page="/login" default-target-url="/welcome" authentication-failure-url="/login?error" username-parameter="user-name" password-parameter="pwd"/> <security:logout logout-success-url="/login?logout"/> <!-- XML 配置中默认csrf是关闭的,此处设置为打开 如果这里打开csrf,则在form表单中需要添加 <input type="hidden" th:name="${_csrf.parameterName}" th:value="${_csrf.token}" /> --> <security:csrf /> </security:http>
其中:
login-page指定的用户自定义的登录页面
default-target-url登录成功以后默认跳转到的页面
authentication-failure-url登录失败以后跳转到的页面
username-parameter指定登录表单中用户名的input中name,如果这里不配置,则默认为username
password-parameter指定登录表单中密码的input中name,如果这里不配置,则默认为password
logout-success-url成功退出以后跳转到的地址
其他见注释
二、添加login.html
<!DOCTYPE html> <html xmlns:th="http://www.thymeleaf.org"> <head> <meta charset="UTF-8" /> <title>login</title> <style> .error { padding: 15px; margin-bottom: 20px; border-radius: 4px; color: #a94442; background-color: #f2dede; border: 1px solid #ebccd1; } .msg { padding: 15px; margin-bottom: 20px; border-radius: 4px; color: #31708f; background-color: #d9edf7; border: 1px solid #bce8f1; } #login-box { width: 300px; padding: 20px; margin: 100px auto; background: #fff; -webkit-border-radius: 2px; -moz-border-radius: 2px; border: 1px solid #000; } .hide { display: none; } .show { display: block; } </style> </head> <body> <div id="login-box"> <h1>Spring Security 自定义登录页面</h1> <div class="error" th:class="${error}? 'show error' : 'hide'" th:text="${error}"></div> <div class="msg" th:class="${msg}? 'show msg' : 'hide'" th:text="${msg}"></div> <form name='loginForm' action="/login" method='POST'> <table> <tr> <td>用户名:</td> <td><input type='text' name='user-name' /></td> </tr> <tr> <td>密码:</td> <td><input type='password' name='pwd' /></td> </tr> <tr> <td colspan='2'> <input type="submit" value="提交" /> </td> </tr> </table> <input type="hidden" th:name="${_csrf.parameterName}" th:value="${_csrf.token}" /> </form> </div> </body> </html>
<form name='loginForm' th:action="@{/login}" method='POST'>
<table>
<tr>
<td>用户名:</td>
<td><input type='text' name='user-name' autofocus/></td>
</tr>
<tr>
<td>密码:</td>
<td><input type='password' name='pwd' /></td>
</tr>
<tr>
<td colspan='2'>
<input type="submit" value="提交" />
</td>
</tr>
</table>
</form>
使用这个表单也可以进行登录,提交时候自动添加_csrf属性
三、修改admin.html
<!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:th="http://www.thymeleaf.org"> <head> <meta charset="UTF-8"/> <title>admin</title> </head> <body> <h1 th:text="|标题: ${title}|">Title : XXX</h1> <h1 th:text="|信息: ${message}|">Message : XXX</h1> <h2><a href="javascript:formSubmit()">Logout</a></h2> <!-- csrf for logout--> <form action="/logout" method="post" id="logoutForm"> <input type="hidden" th:name="${_csrf.parameterName}" th:value="${_csrf.token}" /> </form> <script> function formSubmit() { document.getElementById("logoutForm").submit(); } </script> </body> </html>
<!-- 同样可以进行正常退出,自动加入了_csrf的属性值 -->
<form th:action="@{/logout}" method="post" id="logoutForm"></form>
如果使用这种表单也可以实现退出,提交时候自动添加_csrf属性
四、修改HelloController文件,添加代码:
@RequestMapping(value = "/login", method = RequestMethod.GET) public ModelAndView login( @RequestParam(value = "error", required = false) String error, @RequestParam(value = "logout", required = false) String logout) { ModelAndView model = new ModelAndView(); if (error != null) { model.addObject("error", "不正确的用户名和密码"); } if (logout != null) { model.addObject("msg", "你已经成功退出"); } model.setViewName("login"); return model; }
启动程序:访问http://localhost:8010/login 跳转到自定义的登录页面
可以自行测试登录成功和失败的提示
下面采用注解方式,在前面的采用注解方式实现security和自定义登录页基础之上,把配置spring-security.xml的过程改成注解方式即可
项目结构如下:
修改SecurityConfig文件
package com.petter.config; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.context.annotation.Configuration; import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder; import org.springframework.security.config.annotation.web.builders.HttpSecurity; import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity; import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter; /** * 相当于spring-security.xml中的配置 * @author hongxf * @since 2017-03-08 9:30 */ @Configuration @EnableWebSecurity public class SecurityConfig extends WebSecurityConfigurerAdapter { /** * 在内存中设置三个用户 * @param auth * @throws Exception */ @Autowired public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception { auth.inMemoryAuthentication().withUser("hongxf").password("123456").roles("USER"); auth.inMemoryAuthentication().withUser("admin").password("123456").roles("ADMIN"); auth.inMemoryAuthentication().withUser("dba").password("123456").roles("DBA"); } /** * 配置权限要求 * 采用注解方式,默认开启csrf * @param http * @throws Exception */ @Override protected void configure(HttpSecurity http) throws Exception { http.authorizeRequests() .antMatchers("/admin/**").access("hasRole('ROLE_ADMIN')") .antMatchers("/dba/**").access("hasRole('ROLE_ADMIN') or hasRole('ROLE_DBA')") .and() .formLogin().loginPage("/login") .defaultSuccessUrl("/welcome").failureUrl("/login?error") .usernameParameter("user-name").passwordParameter("pwd") .and() .logout().logoutSuccessUrl("/login?logout") .and() .csrf(); } }
修改HelloController文件,添加
@RequestMapping(value = "/login", method = RequestMethod.GET) public ModelAndView login( @RequestParam(value = "error", required = false) String error, @RequestParam(value = "logout", required = false) String logout) { ModelAndView model = new ModelAndView(); if (error != null) { model.addObject("error", "不正确的用户名和密码"); } if (logout != null) { model.addObject("msg", "你已经成功退出"); } model.setViewName("login"); return model; }
启动程序测试成功
