SpringBoot-28-springSecurity注销和权限控制

8.5 springSecurity注销和权限控制

继续上一节,在Security授权处设置开启注销，注意使用logoutSuccessUrl(“/”)方法

package com.zk.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.WebSecurityConfiguration;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;

/**

//AOP思想，非拦截器
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    //链式编程--  授权规则
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        //首页所有人可以访问，功能页只有对应有权限的人才能访问
        //请求授权的页面
        http.authorizeRequests()
                .antMatchers("/").permitAll()  //首页所有人访问
                .antMatchers("/level1/**").hasRole("vip1")
                .antMatchers("/level2/**").hasRole("vip2")
                .antMatchers("/level3/**").hasRole("vip3");
        //没有权限默认到登陆页，开启登陆页
        http.formLogin();

        http.httpBasic();

         //防止网站攻击工具：get易受攻击且是csrf攻击，改为post
        //新版本不用关闭
        //http.csrf().disable(); //springboot默认开启csrf是正确的，会防止跨站请求攻击，
        // 低版本的springboot需要关闭csrf，登陆失败存在的原因 或者设置为post方式注销
        
        //开启注销功能，注销跳到首页
        http.logout().logoutSuccessUrl("/");
    }
    }

退出失败问题：

get请求导致，设置为post方式注销

springboot默认开启csrf导致

springboot版本问题，新版本没问题

然后导入security-thymeLeaf整合包，可以在thymeLeaf写security操作

<!--security-thymeLeaf整合包,thymeLeaf写security操作-->
<dependency>
    <groupId>org.thymeleaf.extras</groupId>
    <artifactId>thymeleaf-extras-springsecurity5</artifactId>
</dependency>

注意在index.html页面中引入的命名空间springsecurity5的命名空间是/extras/spring-security，这样才有sec命名提示

<html lang="en" xmlns:th="http://www.thymeleaf.org"
      xmlns:sec="http://www.thymeleaf.org/extras/spring-security">

在index.html里面用thymeLeaf操作security内容来实现根据security权限动态的显示菜单

授权是给用户角色来授权

sec:authorize=“”授权，通过这个用户是否有这个角色，来判断是否通过授权

sec:authentication=“name” 认证信息

<!DOCTYPE html>
