java - spring boot 怎么把session 放到redis

Question

通过第三方登录接口验证通过后返回登录信息，我将登录信息的用户 id 和 ticket 作为键和值存在 session 中

具体是这样子：

HttpSession session= request.getSession();
session.setAttribute(UserId,ticket);

现在想 将这个session 存到redis.

具体的准备差不多按照 http://docs.spring.io/spring-session/docs/current/reference/html5/guides/boot.html 配置了

还需要做什么 不太懂。

Answer 1

如果你的redis安装正确，spring的部分也按照配置完成了，那你运行下试试，理论上不需要再做什么额外的东西了。

你原先的代码，类似：

HttpSession session= request.getSession();
session.setAttribute(UserId,ticket);

不需要有任何变动，因为The Spring configuration is responsible for creating a Servlet Filter that replaces the HttpSession implementation with an implementation backed by Spring Session，所以，面向接口编程真的好灵活，有木有！^^

Answer 2

直接在启动类上加入@EnableRedisHttpSession注解即可，引用一段spring boot官方文档的内容，

Spring Session provides support for managing a user’s session information. If you are writing a web application and Spring Session and Spring Data Redis are both on the classpath, Spring Boot will auto-configure Spring Session through its @EnableRedisHttpSession. Session data will be stored in Redis and the session timeout can be configured using the server.session.timeout property.

建议在web容器上做配置~
