用户认证和授权

一、沿用上一篇博客项目

二、测试

2.1、导入SpringSecurity的依赖

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-security</artifactId>
        </dependency>

2.2、在com.massimo.config包下新建SecurityConfig类

package com.massimo.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
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    //链式编程
    //授权
    @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
        //请求授权的规则
        http.authorizeRequests()
                .antMatchers("/").permitAll()
                .antMatchers("/level1/**").hasRole("vip1")
                .antMatchers("/level2/**").hasRole("vip2")
                .antMatchers("/level3/**").hasRole("vip3");

        //没有权限默认会到登录页面，需要开启登录的页面
        http.formLogin();
    }

    //认证,spring 2.1.x 可以直接使用
    //密码编码：PasswordEncoder
    //在Spring Security 5.0+  新增了很多的加密方法
    @Override
    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("Massimo").password(new BCryptPasswordEncoder().encode("123456")).roles("vip2","vip3")
                .and()
                .withUser("root").password(new BCryptPasswordEncoder().encode("123456")).roles("vip1","vip2","vip3")
                .and()
                .withUser("guest").password(new BCryptPasswordEncoder().encode("123456")).roles("vip1");
    }
}
