rememberMe功能

1.引入依赖

<dependency>
  <groupId>mysql</groupId>
  <artifactId>mysql-connector-java</artifactId>
  <version>8.0.18</version>
</dependency>

<dependency>
  <groupId>org.mybatis.spring.boot</groupId>
  <artifactId>mybatis-spring-boot-starter</artifactId>
  <version>2.1.1</version>
</dependency>

2.配置文件

spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://127.0.0.1/security?characterEncoding=utf8&useUnicode=true&useSSL=false&serverTimezone=GMT%2B8&allowPublicKeyRetrieval=true
    username: root
    password:

3.配置类

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Autowired
    private MyAccessDeniedHandler myAccessDeniedHandler;

    @Autowired
    private DataSource dataSource;

    @Autowired
    private PersistentTokenRepository persistentTokenRepository;

    @Autowired
    private UserDetailsService userDetailsService;

    @Bean
    public PasswordEncoder getPassword(){
        return new BCryptPasswordEncoder();
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.formLogin()
                .loginPage("/login.html")
                .loginProcessingUrl("/login")
                .successForwardUrl("/toIndex")
                .failureForwardUrl("/toError");
                
        http.authorizeRequests()
                .antMatchers("/css/**","js/**","**/*.png").permitAll()
                .antMatchers("/login.html").permitAll()
                .antMatchers("/error.html").permitAll()
                .anyRequest().authenticated();

        http.rememberMe()
                //设置数据源
                .tokenRepository(persistentTokenRepository)
//                .rememberMeParameter()
                //默认俩周
                .tokenValiditySeconds(60)
                .userDetailsService(userDetailsService);

        http.csrf().disable();
    }

    @Bean
    public PersistentTokenRepository persistentTokenRepository(){
        JdbcTokenRepositoryImpl jdbcTokenRepository = new JdbcTokenRepositoryImpl();
        //设置数据源
        jdbcTokenRepository.setDataSource(dataSource);
        //自动建表 第一次使用 第二次报错
        jdbcTokenRepository.setCreateTableOnStartup(true);
        return jdbcTokenRepository;
    }
}

4.login.html

<body>
    <form action="/login" method="post">
        Username : <input type="text" name="username"><br>
