<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration PUBLIC "-//log4j/log4j Configuration//EN" "log4j.dtd">

<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">
    
    <appender name="STDOUT" class="org.apache.log4j.ConsoleAppender">
       <layout class="org.apache.log4j.PatternLayout"> 
          <param name="ConversionPattern" value="%d %-5p %c.%M:%L - %m%n"/> 
       </layout> 
    </appender>
 
    <!-- specify the logging level for loggers from other libraries -->
    <logger name="com.opensymphony">
    	<level value="DEBUG" />
    </logger>

    <logger name="org.apache.struts2">
    	 <level value="DEBUG" />
    </logger>
  
   <!-- for all other loggers log only debug and above log messages -->
     <root>
        <priority value="INFO"/> 
        <appender-ref ref="STDOUT" /> 
     </root> 
    
</log4j:configuration>

classpath下添加struts.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC

  </welcome-file-list>
  					 
    <filter>

        <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
    </filter>

     <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
    
</web-app>

新建页面index.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Struts 2 Application - Welcome</title>
</head>
<body>
	<h3>Welcome To Struts 2!</h3>

</body>
</html>

配置pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>org.apache.struts</groupId>
  <artifactId>struts</artifactId>
  <packaging>war</packaging>
  <version>0.0.1-SNAPSHOT</version>
  <name>struts Maven Webapp</name>
  <url>http://maven.apache.org</url>
  <dependencies>
  	<dependency>
	    <groupId>org.apache.struts</groupId>

	    <artifactId>log4j</artifactId>
	    <version>1.2.14</version>

  <build>
    <finalName>struts</finalName>
  </build>
</project>

finalName是项目名称

运行maven命令：
