工作的時(shí)候接受老項(xiàng)目藍(lán)凌v13，在使用eclipse 的tomcat 啟動(dòng) ssh 項(xiàng)目的時(shí)候，啟動(dòng)遇到相關(guān)錯(cuò)誤：

  java.lang.NoSuchMethodException: org.apache.catalina.deploy.WebXml addFilter

反手百度，大部分是 答案是在tomcat/conf/context.xml 加上一句配置,

<Loader delegate="true"/>

整個(gè)配置是

<?xml version="1.0" encoding="UTF-8"?>

加入之后項(xiàng)目正常運(yùn)行，但是如果關(guān)閉tomcat 之后的話，該文件會(huì)恢復(fù)默認(rèn)值，重啟啟動(dòng)需要繼續(xù)添加這一段話，不知道為啥。
