詳解springboot springsecuroty中的註銷和權限控制問題
上篇文章給大傢介紹瞭springboot對接第三方微信授權及獲取用戶的頭像和昵稱等等
1 賬戶註銷
1.1 在SecurityConfig中加入開啟註銷功能的代碼
src/main/java/com/lv/config/SecurityConfig.java
package com.lv.config; 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; import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder; //AOP : 攔截器! @EnableWebSecurity public class SecurityConfig extends WebSecurityConfigurerAdapter { //授權 @Override public void configure(HttpSecurity http) throws Exception { //首頁所有人都可以訪問,功能頁隻有對應的有權限的人才能訪問 //請求授權的規則~(鏈式編程) http.authorizeRequests() .antMatchers("/").permitAll() .antMatchers("/level1/**").hasRole("vip1") .antMatchers("/level2/**").hasRole("vip2") .antMatchers("/level3/**").hasRole("vip3"); //沒有權限默認會跳轉到登錄頁,需要開啟登錄頁面 http.formLogin(); //註銷,開啟瞭註銷功能,跳到首頁 http.logout().logoutSuccessUrl("/"); //防止跨站工具, get,post http.csrf().disable();//關閉csrf功能,註銷失敗可能的原因 } //認證,springboot 2.1.x 可以直接使用 //密碼編碼:PasswordEncoder //在Spring Security 5.0+ 新增瞭很多加密方法~ protected void configure(AuthenticationManagerBuilder auth) throws Exception { //這些數據正常應該從數據庫中讀 auth.inMemoryAuthentication().passwordEncoder(new BCryptPasswordEncoder()) .withUser("lv").password(new BCryptPasswordEncoder().encode("123456")).roles("vip2","vip3") .and() .withUser("root").password(new BCryptPasswordEncoder().encode("123456")).roles("vip1","vip2","vip3") .withUser("guest").password(new BCryptPasswordEncoder().encode("123456")).roles("vip1"); }
1.2 在index.html 添加註銷的按鈕
src/main/resources/templates/index.html
<!--登錄註銷--> <div class="right menu"> <div> <a class="item" th:href="@{/toLogin}"> <i class="address card icon"></i>登錄 </a> </div> <div> <a class="item" th:href="@{/logout}"> <i class="sign-out icon"></i>註銷 </a> </div> </div>
1.3 啟動項目測試
訪問登錄頁面,登錄 guest 賬戶,該賬戶可以訪問 level1的頁面
登錄成功後,點擊 level1的鏈接,成功跳轉到 level 頁面,然後點擊註銷按鈕
彈回到首頁,再次點擊點擊 level1 頁面
跳轉到瞭登錄頁面
說明賬戶註銷成功
2 權限控制
2.1 導入springsecurity和thymeleaf的整合依賴
pom.xml
<!-- springSecurity和thymeleaf整合包 --> <dependency> <groupId>org.thymeleaf.extras</groupId> <artifactId>thymeleaf-extras-springsecurity4</artifactId> <version>3.0.2.RELEASE</version> </dependency>
2.2 springboot版本降級
pom.xml
<parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.0.9.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent>
必須將springboot的版本降到2.0.9以下,否則 sec:authorize="isAuthenticated()" 不會生效.版本降低後,需要手動導入junit依賴,否則測試類會報錯
<dependency> <groupId>org.junit.jupiter</groupId> <artifactId>junit-jupiter</artifactId> <version>RELEASE</version> <scope>test</scope> </dependency>
2.3 引入約束
在index.html的頭文件中添加springsecurity和thymeleaf的整合約束
src/main/resources/templates/index.html
<html xmlns:th="http://www.thymeleaf.org" xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity4">
2.4 修改頁面代碼
主要修改兩部分,一部分是登錄狀態下顯示用戶名,和註銷按鈕,未登錄顯示登錄按鈕 通過 sec:authorize="isAuthenticated()" 實現.另一部分是根據登錄用戶的權限顯示不同的頁面菜單,通過 sec:authorize="hasRole('vip1')" 實現.
src/main/resources/templates/index.html
<!DOCTYPE html> <html xmlns:th="http://www.thymeleaf.org" xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity4"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1"> <title>首頁</title> <!--semantic-ui--> <link href="https://cdn.bootcss.com/semantic-ui/2.4.1/semantic.min.css" rel="stylesheet"> <link th:href="@{/qinjiang/css/qinstyle.css}" rel="stylesheet"> </head> <body> <!--主容器--> <div class="ui container"> <div class="ui segment" id="index-header-nav" th:fragment="nav-menu"> <div class="ui secondary menu"> <a class="item" th:href="@{/index}">首頁</a> <!--登錄註銷--> <div class="right menu"> <!--如果未登錄:顯示登錄按鈕--> <div sec:authorize="!isAuthenticated()"> <a class="item" th:href="@{/toLogin}"> <i class="address card icon"></i>登錄 </a> </div> <!--如果已登錄:顯示用戶名和註銷按鈕--> <div sec:authorize="isAuthenticated()"> <a class="item"> 用戶名:<span sec:authentication="name"></span> </a> </div> <div sec:authorize="isAuthenticated()"> <a class="item" th:href="@{/logout}"> <i class="sign-out icon"></i>註銷 </a> </div> </div> </div> </div> <div class="ui segment" style="text-align: center"> <h3>Spring Security Study by 秦疆</h3> </div> <div> <br> <div class="ui three column stackable grid"> <!--菜單根據用戶的角色動態實現--> <div class="column" sec:authorize="hasRole('vip1')"> <div class="ui raised segment"> <div class="ui"> <div class="content"> <h5 class="content">Level 1</h5> <hr> <div><a th:href="@{/level1/1}"><i class="bullhorn icon"></i> Level-1-1</a></div> <div><a th:href="@{/level1/2}"><i class="bullhorn icon"></i> Level-1-2</a></div> <div><a th:href="@{/level1/3}"><i class="bullhorn icon"></i> Level-1-3</a></div> </div> </div> </div> </div> <div class="column" sec:authorize="hasRole('vip2')"> <div class="ui raised segment"> <div class="ui"> <div class="content"> <h5 class="content">Level 2</h5> <hr> <div><a th:href="@{/level2/1}"><i class="bullhorn icon"></i> Level-2-1</a></div> <div><a th:href="@{/level2/2}"><i class="bullhorn icon"></i> Level-2-2</a></div> <div><a th:href="@{/level2/3}"><i class="bullhorn icon"></i> Level-2-3</a></div> </div> </div> </div> </div> <div class="column" sec:authorize="hasRole('vip3')"> <div class="ui raised segment"> <div class="ui"> <div class="content"> <h5 class="content">Level 3</h5> <hr> <div><a th:href="@{/level3/1}"><i class="bullhorn icon"></i> Level-3-1</a></div> <div><a th:href="@{/level3/2}"><i class="bullhorn icon"></i> Level-3-2</a></div> <div><a th:href="@{/level3/3}"><i class="bullhorn icon"></i> Level-3-3</a></div> </div> </div> </div> </div> </div> </div> </div> <script th:src="@{/qinjiang/js/jquery-3.1.1.min.js}"></script> <script th:src="@{/qinjiang/js/semantic.min.js}"></script> </body> </html>
2.5 重啟程序測試
未登錄頁面
登錄 lv 用戶的頁面
登錄 geust 用戶的頁面
登錄 root 用戶的頁面
頁面顯示都不同,權限控制成功實現
