Struts2的簡單實現

寫這篇博客是因爲配置這個簡單的demo花費了2個小時的時間，經歷瞭如下錯誤

java.util.concurrent.ExecutionException: org.apache.catalina.Li

Caused by: java.lang.NoClassDefFoundError: Lorg/apache/logging/log4j/Logger;

java.util.concurrent.ExecutionException: org.apache.catalina.LifecycleExcept

java.lang.ClassNotFoundException: org.apache.struts2.dispatcher.ng.filter.St

java.lang.NoSuchMethodException

解決方法是通過導入相關的jar包實現的，這裏出現了由於jar版本不同而導致的錯誤

一、struts.xml的配置

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
"http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
<package name="default" namespace="/" extends="struts-default">
<action name="helloworld" class="com.tui.HelloAction">
<result name="ok">/hello.jsp</result>
</action>
</package>
</struts>

二、web.xml的配置

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">
  <display-name>qweq</display-name>
 <filter>
    <filter-name>struts2</filter-name>
    <filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class>
 </filter>
 <filter-mapping>
   <filter-name>struts2</filter-name>
   <url-pattern>/*</url-pattern>
 </filter-mapping>
</web-app>
