小编给大家分享一下SpringBoot springsecuroty中注销和权限控制问题的示例分析，相信大部分人都还不怎么了解，因此分享这篇文章给大家参考一下，希望大家阅读完这篇文章后大有收获，下面让我们一起去了解一下吧！

1 账户注销

1.1 在SecurityConfig中加入开启注销功能的代码

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 : 拦截器!@EnableWebSecuritypublic class SecurityConfig extends WebSecurityConfigurerAdapter {    //授权    @Override    public void configure(HttpSecurity http) throws Exception {        //首页所有人都可以访问,功能页只有对应的有权限的人才能访问        //请求授权的规则~(链式编程)        http.authorizeRequests()                .antMatchers("/").permitAll()                .antMatchers("/level1/**").hasRole("vip1")                .antMatchers("/level2/**").hasRole("vip2")                .antMatchers("/level3/**").hasRole("vip3");        //没有权限默认会跳转到登录页,需要开启登录页面        http.fORMLogin();        //注销,开启了注销功能,跳到首页        http.loGout().logoutSuccessUrl("/");        //防止跨站工具, get,post        http.csrf().disable();//关闭csrf功能,注销失败可能的原因    }    //认证,springboot 2.1.x 可以直接使用    //密码编码:PasswordEncoder    //在Spring Security 5.0+ 新增了很多加密方法~    protected void configure(AuthenticationManagerBuilder auth) throws Exception {        //这些数据正常应该从数据库中读        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 添加注销的按钮

src/main/resources/templates/index.html

<!--登录注销--><div class="right menu">    <div>        <a class="item" th:href="@{/toLogin}">            <i class="address card icon"></i>登录        </a>    </div>    <div>        <a class="item" th:href="@{/logout}">            <i class="sign-out icon"></i>注销        </a>    </div></div>

1.3 启动项目 测试

访问登录页面,登录 guest 账户,该账户可以访问 level1的页面

2 权限控制

2.1 导入springsecurity和thymeleaf的整合依赖

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版本降级

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>

必须将springboot的版本降到2.0.9以下,否则 sec:authorize="isAuthenticated()" 不会生效.版本降低后,需要手动导入junit依赖,否则测试类会报错

<dependency>    <groupId>org.junit.jupiter</groupId>    <artifactId>junit-jupiter</artifactId>    <version>RELEASE</version>    <scope>test</scope></dependency>

2.3 引入约束

在index.html的头文件中添加springsecurity和thymeleaf的整合约束

src/main/resources/templates/index.html

<html xmlns:th="http://www.thymeleaf.org"      xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity4">

2.4 修改页面代码

主要修改两部分,一部分是登录状态下显示用户名,和注销按钮,未登录显示登录按钮通过 sec:authorize="isAuthenticated()" 实现.另一部分是根据登录用户的权限显示不同的页面菜单,通过 sec:authorize="hasRole('vip1')" 实现.

src/main/resources/templates/index.html
