上篇文章给大家介绍了springboot对接第三方微信授权及获取用户的头像和昵称等等
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!
@EnableWebSecurity
public 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
登录成功后,点击 level1的链接,成功跳转到 level 页面,然后点击注销按钮
弹回到首页,再次点击点击 level1 页面
跳转到了登录页面
说明账户注销成功
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
<!DOCTYPE html>
