SpringBoot搭建基於Apache Shiro+Redis的分布式Session共享功能

本文轉載自查看原文 2017-11-02 19:09 1483 Java/ Shiro/ Redis/ SpringBoot

我們在上一遍文檔中已經完成了Shiro驗證功能。（http://www.cnblogs.com/nbfujx/p/7773789.html），在此基礎上我們將完成分布式Session共享功能。

Redis的使用

Maven Plugin添加Redis相關jar包

1   <dependency>
2             <groupId>org.springframework.boot</groupId>
3             <artifactId>spring-boot-starter-data-redis</artifactId>
4         </dependency>

新增RedisCacheManager，RedisSessionDAO，sessionManager相關bean，

securityManager 增加 securityManager.setSessionManager(sessionManager());

Shiro-Redis的使用驗證

先進行登錄驗證操作

查看redis存儲數據

進行數據查詢

查看日志是否從redis獲取
