spring boot security学习

自定以securityconfig

package com.cai.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;

import java.beans.Encoder;

//AOP横切
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    //授权
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        //首页所有人可以访问,但是里面的功能页只有对应有权限的人才可以访问
        //请求授权的规则
        http.authorizeRequests()
                .antMatchers("/").permitAll()
                .antMatchers("/level1/**").hasRole("vip1")
                .antMatchers("/level2/**").hasRole("vip2")
                .antMatchers("/level3/**").hasRole("vip3");

        //没有权限默认回到登录页面,需要开启登录的页面
        http.formLogin().loginPage("/toLogin");

        //防止网站攻击：get不安全，post
        //关闭csrf攻击功能
        http.csrf().disable();

        //注销,开启了注销功能,跳到首页
        http.logout().logoutSuccessUrl("/");

        //开启记住我功能 cookie,默认保存两周，自定义接受前端的参数
        http.rememberMe().rememberMeParameter("remember");
    }

    //认证，springboot2.1.x 可以直接使用
    //如果出现500说明版本过高，需要密码加密：PasswordEncoder
    //在spring security5.0+ 新增了很多的加密方式
    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        //这些数据正常应该从数据库里面拿
        auth.inMemoryAuthentication().passwordEncoder(new BCryptPasswordEncoder())
                .withUser("admin").password(new BCryptPasswordEncoder().encode("123456")).roles("vip2","vip3")
                .and()
                .withUser("caiji").password(new BCryptPasswordEncoder().encode("123456")).roles("vip1","vip2","vip3")
                .and()
                .withUser("guest").password(new BCryptPasswordEncoder().encode("123456")).roles("vip1");
    }
}

创建routercontroller

package com.cai.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;

/**
 * @BelongsProject:IntelliJ IDEA
 * @Package:com.cai.controller
 * @Author:superman
 * @CreateTime:2021--01--17 10:48
 * @Description:
 */
@Controller
public class RouterController {

    @RequestMapping({"/","/index"})
    public String index(){
        return "index";
    }

    @RequestMapping("/toLogin")
    public String toLogin(){
        return "views/login";
    }

    @RequestMapping("/level1/{id}")
    public String level1(@PathVariable("id") int id){
        return "views/level1/"+id;
    }

    @RequestMapping("/level2/{id}")
    public String level2(@PathVariable("id") int id){
        return "views/level2/"+id;
    }

    @RequestMapping("/level3/{id}")
    public String level3(@PathVariable("id") int id){
        return "views/level3/"+id;
    }

}
