看例外是缺少CarrierRefresher這個類，但是在WEB-INF/lib下有包含這個類的jar包
uj5u.com熱心網友回復：
首選在排除了拼寫錯誤和路徑錯誤之后……你要確定下你的程式呼叫的真的是這個lib目錄下的這個jar么？ 搜一下是不是有其他版本的core-io*.jar在你的tomcat目錄中， 比如war包之類的……
uj5u.com熱心網友回復：
樓主這個是不是本地跑沒問題, linux啟動就到不到包了, 我這邊遇到的情況就是啟動階段找jar包的時候少了個根目錄, 直接找 usr/local/tomcat/webapps/WEB-INF/lib這路徑去了, 前面沒有 / 號一直報錯轉載請註明出處，本文鏈接：https://www.uj5u.com/caozuo/181212.html
