1. 自定义 用户认证、权限

package com.hanhuide.core.service.impl;
    
    import org.springframework.security.core.GrantedAuthority;
    import org.springframework.security.core.authority.SimpleGrantedAuthority;
    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.ArrayList;
    import java.util.Collection;
    
    /**
     * @program: maven
     * @description:用户认证、权限
     * @author: 韩惠德
     * @create: 2019-12-26 11:59
     * @version: 1.0
     **/
    @Service("userDetailsService")
    public class CustomUserDetailsService implements UserDetailsService {
        @Override
        public UserDetails loadUserByUsername(String userName) throws UsernameNotFoundException {
            System.out.println(userName);
            Collection<GrantedAuthority> authorities = new ArrayList<>();
            authorities.add(new SimpleGrantedAuthority("数据库中自定义权限"));//默认为role_admin(大写)  
          // 返回UserDetails实现类
            return new User("韩惠德", "$2a$10$NMePrBMYcdqF77zIpt3fL.L.OuY5VFB3VneEAutVFVNgN/HMyul9K", authorities);//密码必须加密
        }
    
        public static void main(String[] args) {
            BCryptPasswordEncoder passwordEncoder = new BCryptPasswordEncoder();
            String password = passwordEncoder.encode("hanhuide");
            System.out.println(password);
        }
    }

2. Spring Security 的配置类

package com.hanhuide.core.config;
    
    import com.hanhuide.core.service.impl.CustomUserDetailsService;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
    import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;
    import org.springframework.security.config.annotation.web.builders.HttpSecurity;
    import org.springframework.security.config.annotation.web.builders.WebSecurity;
    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;
    
    /**
     * @program: maven
     * @description:
     * @author: 韩惠德
     * @create: 2019-12-26 11:56
     * @version: 1.0
     **/
    @Configuration
    @EnableWebSecurity
    @EnableGlobalMethodSecurity(prePostEnabled = true)
    public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
        @Autowired
        private CustomUserDetailsService userDetailsService;
    
        @Override
        protected void configure(AuthenticationManagerBuilder auth) throws Exception {
            auth.userDetailsService(userDetailsService).passwordEncoder(new BCryptPasswordEncoder());//引入自定义权限的判断
        }
    
        @Override
        protected void configure(HttpSecurity http) throws Exception {
            http.authorizeRequests()
                    // 如果有允许匿名的url，填在下面
                    .anyRequest().authenticated()
                    .and()
                    // 设置登陆页
                    .formLogin()
                    // 设置登陆成功页
                    .defaultSuccessUrl("/ceshi").permitAll()
                    .and()
                    .logout().permitAll();
    
            // 关闭CSRF跨域
            http.csrf().disable();
        }
    
        @Override
        public void configure(WebSecurity web) throws Exception {
            // 设置拦截忽略文件夹，可以对静态资源放行
            web.ignoring().antMatchers("/css/**", "/js/**");
        }
    }

3. 这样就可以用自己的数据库中的用户名密码登录了

4.在WebSecurityConfig新加一行

http.rememberMe(); 就可以实现记住密码功能

完！！！
