  • Spring Security 实现记住我

    开篇一张图,道理全靠悟。

    示例如下:

    1.    新建Maven项目  remember_me

    2.   pom.xml

    12.   js/jquery-3.3.1.min.js 可在官网下载

    https://code.jquery.com/jquery-3.3.1.min.js

    13.   创建数据库

    DROP DATABASE IF EXISTS security;
    CREATE DATABASE security;
    USE security;
    create table persistent_logins (
        username varchar(64) not null, 
        series varchar(64) primary key, 
        token varchar(64) not null, 
        last_used timestamp not null
    );

    14.   运行 RememberMeStarter.java , 启动测试

    浏览器输入首页  http://localhost:8080/main.html

    地址栏自动跳转到登录页面,如下:

    输入如下信息:

    User:Logan

    Password:123456

     单击【登录】按钮,自动跳转到首页。

    观察数据库,此时自动生成一条记录,username字段值为登录时使用用户名,记住我Token信息已生成。

    如下所示:

    测试【记住我】 功能是否生效

    关闭浏览器重新打开,或者关闭系统重新启动,再次访问首页,页面不再跳转到登录页,直接显示首页信息。

    如下所示:
