Spring Boot + shiro 去除Redis缓存

  • 记录一些开发日常
  • 第一步：修改ShiroConfig
  • 第二步：新增shiro-ehcache.xml
  • 第三步：注释pom引入的Redis依赖


记录一些开发日常

之前的项目shiro都是和Redis整合在一起的，直到甲方要求项目部署到国产服务器上，国产服务器不支持Redis怎么办，只能改喽。
网上搜一下，修改方案千奇百怪，自己动手丰衣足食！

第一步：修改ShiroConfig

这一步就是把redis实现的缓存，改用session

第二步：新增shiro-ehcache.xml

在上一步可以看到，增加了一个EhCacheManager 的缓存框架，里面有一个配置文件classpath:shiro-ehcache.xml，这文件创建在哪呢，没错就是resource下

<?xml version="1.0" encoding="UTF-8" ?>
<ehcache>
    <defaultCache
            maxElementsInMemory="1000"
            eternal="false"
            timeToIdleSeconds="120"
            timeToLiveSeconds="120"
            memoryStoreEvictionPolicy="LRU">
    </defaultCache>
</ehcache>

第三步：注释pom引入的Redis依赖

这一步就不用多说了，搜索redis关键字注释依赖，然后clean一下，启动项目看看是否正常
