若依将ehcache改为redis缓存详细教程（364）
若依单体项目，目前的会话信息通过
ehcache存储在本地，不方便集群会话管理，如果你需要将ehcache替换为redis来实现集群会话管理。下面详细介绍一下整合步骤。
一、 删除shiro-ehcache依赖
删除ruoyi-common模块下的pom.xml中的shiro-ehcache依赖
二、添加 redis整合依赖
ruoyi-common模块下的pom.xml文件里添加整合依赖
<!-- shiro整合redis -->
<dependency>
<groupId>org.crazycake</groupId>
<artifactId>shiro-redis</artifactId>
<version>3.3.1</version>
<exclusions>
<exclusion>
<groupId>org.apache.velocity</groupId>
<artifactId>velocity</artifactId>
</exclusion>
</exclusions>
</dependency>
<!-- springboot整合redis -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
三、添加redis配置文件
ruoyi-admin模块下的application-druid.yml文件中添加redis配置
# 数据源配置
spring:
# redis配置
redis:
database: 0
host: 127.0.0.1
port: 6379
password:
timeout: 6000ms # 连接超时时长（毫秒）
lettuce:
pool:
max-active: 1000 # 连接池最大连接数（使用负值表示没有限制）
max-wait: -1ms # 连接池最大阻塞等待时间（使用负值表示没有限制）
max-idle: 10 # 连接池中的最大空闲连接
min-idle: 5 # 连接池中的最小空闲连接
四、删除一些ehcache相关的类
（1）删除java类
ruoyi-framework\src\main\java\com\ruoyi\framework\shiro\service\SysShiroService.java
ruoyi-framework\src\main\java\com\ruoyi\framework\shiro\session\OnlineSessionDAO.java
ruoyi-framework\src\main\java\com\ruoyi\framework\shiro\web\filter\online\OnlineSessionFilter.java
ruoyi-framework\src\main\java\com\ruoyi\framework\shiro\web\filter\sync\SyncOnlineSessionFilter.java
ruoyi-framework\src\main\java\com\ruoyi\framework\shiro\web\session\OnlineWebSessionManager.java
ruoyi-framework\src\main\java\com\ruoyi\framework\shiro\web\session\SpringSessionValidationScheduler.java
ruoyi-system\src\main\java\com\ruoyi\system\mapper\SysUserOnlineMapper.java
ruoyi-system\src\main\java\com\ruoyi\system\service\ISysUserOnlineService.java
ruoyi-system\src\main\java\com\ruoyi\system\service\impl\SysUserOnlineServiceImpl.java
（2） 删除ehcache配置文件
ruoyi-admin\src\main\resources\ehcache\ehcache-shiro.xml
（3） 删除mybatis的xml文件
ruoyi-system\src\main\resources\mapper\system\SysUserOnlineMapper.xml
五、加入整合相关代码

六、测试是否集成成功
整合完毕之后，测试验证一下reids是否集成成功，在线用户，缓存监控等功能是否正常。
