搭建ssm的踩坑之路（四）IllegalArgumentException: Cannot find cache

继续上一篇https://blog.****.net/sky_jiangcheng/article/details/86514112，搭建ssm项目过程中，使用cache过程中爆出如下bug，截图如下：

日志如下：

解决方案：

1，在 ehcache.xml 中新增 cache 配置或与使用的 cache要能对应上：

<cache name="cacheTest"
           maxElementsInMemory="1000"
           eternal="false"
           overflowToDisk="true"
           timeToIdleSeconds="10"
           timeToLiveSeconds="20"/>

验证完毕，已解决
