想了解关于SpringSecurity配置403权限访问页面的完整代码的相关内容吗,别团等shy哥发育在本文为您仔细讲解SpringSecurity权限访问页面的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:SpringSecurity权限访问页面,SpringSecurity,403访问页面,下面大家一起来学习吧。

1、未配置之前

在这里插入图片描述

2、开始配置

 2.1 新建一个unauth.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<h1>没有访问的权限</h1>
</body>
</html>

2.2 在继承WebSecurityConfigurerAdapter的配置类中设置

关键代码:

//配置没有权限访问自定义跳转的页面
  http.exceptionHandling()
  .accessDeniedPage("/unauth.html");

配置类完整代码:

package com.atguigu.springsecuritydemo1.config;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
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.WebSecurityConfigurerAdapter;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;

@Configuration
public class SecurityConfigTest extends WebSecurityConfigurerAdapter {

    @Autowired
    private UserDetailsService userDetailsService;

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(userDetailsService).passwordEncoder(password());
    }

    @Bean
    PasswordEncoder password(){
       return new BCryptPasswordEncoder();
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        //退出配置
        http.logout().logoutUrl("/logout")
                .logoutSuccessUrl("/test/hello")
                .permitAll();

        //配置没有权限访问自定义跳转的页面
        http.exceptionHandling().accessDeniedPage("/unauth.html");
        http.formLogin()             //自定义自己编写的登陆页面
            .loginPage("/login.html")    //登录页面设置
            .loginProcessingUrl("/user/login") //登录访问路径
            .defaultSuccessUrl("/success.html").permitAll()    //登录成功之后,跳转路径
            .and().authorizeRequests()
               //设置哪些路径可以直接访问,不需要认证
                .antMatchers("/","/test/hello","/user/login").permitAll()
                //当前登录的用户,只有具有admins权限才可以访问这个路径
               //1、hasAuthority方法
               //.antMatchers("/test/index").hasAuthority("admins")
               //2、hasAnyAuthority方法
              // .antMatchers("/test/index").hasAnyAuthority("admins,manager")
              //3、hasRole方法  ROLE_sale
               .antMatchers("/test/index").hasRole("sale")
                //4、hasAnyRole方法

            .anyRequest().authenticated()
            .and().csrf().disable();    //关闭csrf防护
    }
}

2.3 继承UserDetailsService接口的实现类

package com.atguigu.springsecuritydemo1.service;

import com.atguigu.springsecuritydemo1.entity.Users;
import com.atguigu.springsecuritydemo1.mapper.UsersMapper;
import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.AuthorityUtils;
import org.springframework.security.core.userdetails.User;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.stereotype.Service;

import java.util.List;

@Service("userDetailsService")
public class MyUserDetailService implements UserDetailsService {

    @Autowired
    private UsersMapper usersMapper;

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {

        //调用userMapper中的方法,根据用户名查询数据库
        QueryWrapper<Users> wrapper=new QueryWrapper<>();//条件构造器
        //where username=?
        wrapper.eq("username",username);
        Users users= usersMapper.selectOne(wrapper);
        //判断
        if(users==null){    //数据库没有用户名,认证失败
            throw new UsernameNotFoundException("用户名不存在!");
        }

        List<GrantedAuthority> auths= AuthorityUtils.commaSeparatedStringToAuthorityList("admins,ROLE_sale");
        //从查询数据库返回user对象,得到用户名和密码,返回
        return new User(users.getUsername(),new BCryptPasswordEncoder().encode(users.getPassword()),auths);
    }

}

3、测试

现在我故意将原先的sale改为sale1制造错误

启动项目并访问http://localhost:8111/test/index

在这里插入图片描述

输入lucy 123
