struts2示例

我创建的是maven项目，项目创建好后

首先我们需要创建web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.1" xmlns="http://xmlns.jcp.org/xml/ns/javaee" 
					   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
					   xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
                       					   http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd">
    <display-name>Struts2</display-name>

    <filter>
        <filter-name>struts2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
       <!--  <init-param>
        	<param-name>struts.i18n.encoding</param-name>
        	<param-value>UTF-8</param-value>
        </init-param> -->
    </filter>

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

    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>


</web-app>

接着添加依赖:

<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/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.share</groupId>
  <artifactId>struts2-1</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <packaging>war</packaging>
  <dependencies>
  	<dependency>
  		<groupId>org.apache.struts</groupId>
  		<artifactId>struts2-core</artifactId>
  		<version>2.3.20</version>
  	</dependency>
  	<dependency>
  		<groupId>log4j</groupId>
  		<artifactId>log4j</artifactId>
  		<version>1.2.17</version>
  	</dependency>

  	<dependency>
  		<groupId>org.apache.tomcat</groupId>
  		<artifactId>tomcat-servlet-api</artifactId>
  		<version>8.0.21</version>
  	</dependency>
  </dependencies>
</project>

 创建log4j.xml

<?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 info and above log messages -->
     <root>
        <priority value="INFO"/> 
        <appender-ref ref="STDOUT" /> 
     </root> 
     
</log4j:configuration> 

 创建struts.xml

<?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>
	<constant name="struts.enable.DynamicMethodInvocation" value="false" />
    <constant name="struts.devMode" value="true" />

	<package name="struts2example" namespace="/" extends="struts-default">
		<action name="index">
			<result>/index.jsp</result>
		</action>
	</package>
</struts>

 最后将项目放到服务器中运行，我这里用的是tomcat，接着访问http://localhost:8080/struts2-1
