Spring security OAuth2.0认证授权学习第三天(认证流程)

本来之前打算把第三天写基于Session认证授权的,但是后来视屏看完后感觉意义不大,而且内容简单,就不单独写成文章了;

简单说一下吧,就是通过Servlet的SessionApi

通过实现拦截器的前置拦截

通过setAttr..放入session中

会话中通过getAttr获取

获取不到跳转到登录页面

获取到就判断权限,查看是否有某些特定的权限标识,

如果有就放行,没有就返回无权限

好了说完了;

下面说SpringSecurity

简介:

创建一个Maven项目

本来打算先写理论最后贴代码的,但是感觉不是很清晰,还是直接上代码吧,理论适当即可

22     @RequestMapping(value="/success",produces = ("text/plain;charset=UTF-8"))
23     public String loginSuccess(){
24         return "登录成功";
25     }
26 
27 
28 }

配置完成后使用Maven配置的Tomcat7插件启动

clean tomcat7:run

SpringSecurity提供了登录页面

根据构建的认证信息登录

SpringSecurity自带了退出接口

点击退出后回到登录页面

今天不是很忙,感觉51过后回来,轻松了好多,还有时间学习了
