1.2 application.properties

spring.datasource.url=jdbc:mysql://localhost:3306/demo?serverTimezone=Asia/Shanghai&useUnicode=true&characterEncoding=utf-8
spring.datasource.username=root
spring.datasource.password=root

1.3 建表

create table persistent_logins (username varchar(64) not null, series varchar(64) primary key, token varchar(64) not null, last_used timestamp not null);

1.4 controller

package com.yl.rememberme;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class HelloController {

    @GetMapping("/hello")
    public String hello() {
        return "hello";
    }

    @GetMapping("/admin")
    public String admin() {
        return "admin";
    }
}

1.5 security配置

package com.yl.rememberme;

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.crypto.password.NoOpPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.security.web.authentication.rememberme.JdbcTokenRepositoryImpl;

import javax.sql.DataSource;

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {

//    @Autowired
//    DataSource dataSource;
//
//    @Bean
//    JdbcTokenRepositoryImpl jdbcTokenRepository() {
//        JdbcTokenRepositoryImpl repository = new JdbcTokenRepositoryImpl();
//        repository.setDataSource(dataSource);
//        return repository;
//    }

    @Bean
    PasswordEncoder passwordEncoder() {
        return NoOpPasswordEncoder.getInstance();
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication()
                .withUser("root")
                .password("123")
                .roles("root");
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
//                .antMatchers("/admin")
//                .fullyAuthenticated()
                .anyRequest()
                .authenticated()
                .and()
                .formLogin()
                .permitAll()
                .and()
                .rememberMe() //开启记住我功能
                .key("root123")
//                .tokenRepository(jdbcTokenRepository())
                .and()
                .csrf().disable();
    }
}

2.持久化令牌方案（解决自动登录安全问题方式一）

2.1 security的配置

package com.yl.rememberme;

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.crypto.password.NoOpPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.security.web.authentication.rememberme.JdbcTokenRepositoryImpl;

import javax.sql.DataSource;

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    DataSource dataSource;

    @Bean
    JdbcTokenRepositoryImpl jdbcTokenRepository() {
        JdbcTokenRepositoryImpl repository = new JdbcTokenRepositoryImpl();
        repository.setDataSource(dataSource);
        return repository;
    }

    @Bean
    PasswordEncoder passwordEncoder() {
        return NoOpPasswordEncoder.getInstance();
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication()
                .withUser("root")
                .password("123")
                .roles("root");
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
//                .antMatchers("/admin")
//                .fullyAuthenticated()
                .anyRequest()
                .authenticated()
                .and()
                .formLogin()
                .permitAll()
                .and()
                .rememberMe() //开启记住我功能
                .key("root123")
                .tokenRepository(jdbcTokenRepository())
                .and()
                .csrf().disable();
    }
}

3.二次校验（解决自动登录安全问题方式一）

3.1 security的配置，rememberme功能对/admin接口无效，再次访问/admin接口时需要再次登录

package com.yl.rememberme;

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.crypto.password.NoOpPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.security.web.authentication.rememberme.JdbcTokenRepositoryImpl;

import javax.sql.DataSource;

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    DataSource dataSource;

    @Bean
    JdbcTokenRepositoryImpl jdbcTokenRepository() {
        JdbcTokenRepositoryImpl repository = new JdbcTokenRepositoryImpl();
        repository.setDataSource(dataSource);
        return repository;
    }

    @Bean
    PasswordEncoder passwordEncoder() {
        return NoOpPasswordEncoder.getInstance();
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication()
                .withUser("root")
                .password("123")
                .roles("root");
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
                .antMatchers("/admin")
                .fullyAuthenticated()
                .anyRequest()
                .authenticated()
                .and()
                .formLogin()
                .permitAll()
                .and()
                .rememberMe() //开启记住我功能
                .key("root123")
                .tokenRepository(jdbcTokenRepository())
                .and()
                .csrf().disable();
    }
}
