Intellij IDEA新建struts2專案啟動Tomcat失敗及解決辦法

新建struts專案後,web.xml報錯

解決辦法:將org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter改為

org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter

啟動Tomcat,出現以下錯誤

解決辦法:在WEB-INF目錄下新建lib檔案,將struts的jar包拷貝到lib目錄下

然後將所有jar檔案選中,右擊jar檔案,選擇Add as Library 。

重啟Tomcat成功。
