springsecurity j记住密码

在 Spring Boot 应用中使用 Spring Security 并实现 Remember Me 记住密码功能，实现自动登录
项目地址 https://github.com/helloworlde/SpringSecurity

前置条件：在 Spring Boot 应用中已正确配置 Spring Security

##在页面添加记住密码的复选框

 <input type="checkbox" name="remember-me"/> Remember me

##在 Security Config 配置文件中启用记住密码功能(验证信息存放在内存中)

  • SecurityConfig
    import cn.com.hellowood.springsecurity.security.CustomAuthenticationProvider;
    import cn.com.hellowood.springsecurity.security.CustomUserDetailsService;
    import org.springframework.beans.factory.annotation.Autowired;
    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.WebSecurityConfigurerAdater;
    
    @EnableWebSecurity
    public class SecurityConfig extends WebSecurityConfigurerAdapter {
    
        @Autowired
        private CustomAuthenticationProvider customAuthenticationProvider;
    
        @Autowired
        private CustomUserDetailsService userDetailsService;
    
        @Override
        protected void configure(HttpSecurity http) throws Exception {
            // 任何用户都可以访问以下URI
            http.authorizeRequests()
                    .antMatchers("/", "/login", "/login-error", "/css/**", "/index")
                    .permitAll();
    
            // 其他URI均需要权限校验
            http.authorizeRequests()
                    .anyRequest()
                    .authenticated();
    
            // 只需要以下配置即可启用记住密码
            http.authorizeRequests()
                    .and()
                    .rememberMe();
    
            http.formLogin()
                    .loginPage("/login")
                    .usernameParameter("username")
                    .passwordParameter("password")
                    .successForwardUrl("/user/index")
                    .failureUrl("/login-error");
        }
    
        @Autowired
        public void configureGlobal(AuthenticationManagerBuilder auth) {
            // 为了使用用户名密码校验实现了AuthenticationProvider和UserDetailsService类
            auth.authenticationProvider(customAuthenticationProvider);
            try {
                auth.userDetailsService(userDetailsService);
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }

这样就可以使用记住密码了，选择记住密码登录后会在本地保存 Cookie，下次登录的时候通过 Cookie 校验用户信息；用户登录的信息保存在内存中，当内存断电或被清除之后该 Cookie 即使在有效期内也无法登录。

通过数据库存放校验信息实现记住密码登录

###创建保存校验信息的表(表名和字段值必须为以下内容)

    CREATE TABLE persistent_logins (
      username  VARCHAR(64) NOT NULL,
      series    VARCHAR(64) NOT NULL PRIMARY KEY,
      token     VARCHAR(64) NOT NULL,
      last_used TIMESTAMP   NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
    );

这样就可以实现将校验信息保存在数据库中，下次通过记住密码登录后再次访问页面会根据 Cookie 查找该用户的登录信息，如果登录信息有效则登录成功， 否则重定向到登录页面
