struts2-core-2.3.15.1.jar!/struts-default.xml:53:178核心包加載報錯

Tomcat啓動加載struts2架包時報錯

Unable to load configuration. - bean - jar:file:/D:/apache-tomcat-6.0.362/webapps/beidao/WEB-INF/lib/struts2-core-2.3.15.1.jar!/struts-default.xml:53:178

一般運行struts2必須加載5個核心包：

commons-logging-1.1.3.jar 
freemarker-2.3.19.jar 
ognl-3.0.6.jar 
struts2-core-2.3.15.1.jar 
xwork-2.3.15.1.jar

如果是新版本新版本，就會報如上錯誤，因爲還需要加載另外兩個jar包，當出現上述錯誤時一般就是缺少jar包，將commons-fileupload-2.2.1.jar ，commons-io-1.3.jar 拷到項目根目錄下的\WEB-INF\lib\文件夾內即可。
