Spring security记住我基本原理：
登录的时候，请求发送给过滤器UsernamePasswordAuthenticationFilter,当该过滤器认证成功后，会调用RememberMeService，会生成一个token，将token写入到浏览器cookie，同时RememberMeService里边还有个TokenRepository，将token和用户信息写入到数据库中。这样当用户再次访问系统，访问某一个接口时，会经过一个RememberMeAuthenticationFilter的过滤器，他会读取cookie中的token，交给RememberService，RememberService会用TokenRepository根据token从数据库中查是否有记录，如果有记录会把用户名取出来，再调用UserDetailService根据用户名获取用户信息，然后放在SecurityContext里。
RememberMeAuthenticationFilter在Spring Security中认证过滤器链的倒数第二个过滤器位置，当其他认证过滤器都没法认证成功的时候，就会调用RememberMeAuthenticationFilter尝试认证。
实现：
1，登录表单加上，SpringSecurity在SpringSessionRememberMeServices类里定义了一个常量，默认值就是remember-me
2，根据上边的原理图可知，要配置TokenRepository，把生成的token存进数据库，这是一个配置bean的配置，放在了BrowserSecurityConfig里
3，在configure里配置
4，在BrowserProperties里加上自动登录时间，把记住我时间做成可配置的
//记住我秒数配置
private int rememberMeSeconds = 10;
以下是相关的配置

由于用了记住我 所以现在可以直接访问了哦!
</body>
</html>
到此我们来启动项目,首次访问http://localhost:8787/user会需要我们登录,这里我们进行登录先不勾选记住我:
登录成功后可以正常访问user,然后我们关闭浏览器重新打开 访问http://localhost:8787/user会被返回到登录的页面,这个就是没有任何效果的演示.
然后我们再次登录,并勾选记住我:
这里我们登录成功后关闭浏览器再打开 仍然可以访问http://localhost:8787/user,而且不需要登录:
这里浏览器做了如下的事情:
- 在我们数据库建立表并插入数据
- 然后我们关闭浏览器在访问,它会去库里面查找响应的token,如果有就不用登录直接访问:
到此,rememberme的功能就完成了
