Eclipse搭建Struts2项目

最近在系统性的学习maven，碰到搭建struts2环境，特此记录一下。

1.创建maven工程

2.添加依赖

pom.xml文件内容如下

<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.dylan</groupId>
	<artifactId>02_maven_struts2</artifactId>
	<version>0.0.1-SNAPSHOT</version>
	<packaging>war</packaging>

	<dependencies>
		<dependency>
			<groupId>javax.servlet</groupId>
			<artifactId>javax.servlet-api</artifactId>
			<version>3.0.1</version>
			<scope>provided</scope>
		</dependency>
		<dependency>
			<groupId>org.apache.struts</groupId>
			<artifactId>struts2-core</artifactId>
			<version>2.5.16</version>
		</dependency>
	</dependencies>

	<!--添加JDK插件 -->
	<build>
		<finalName>02_maven_struts2</finalName>
		<plugins>
			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-compiler-plugin</artifactId>
				<configuration>
					<source>1.8</source>
					<target>1.8</target>
					<encoding>UTF-8</encoding>
				</configuration>
			</plugin>
		</plugins>
	</build>
</project>

3.在web.xml中添加struts2核心过滤器

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns="http://java.sun.com/xml/ns/javaee"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
	version="2.5">
	<display-name>02_maven_struts2</display-name>
	<welcome-file-list>
		<welcome-file>index.html</welcome-file>
		<welcome-file>index.htm</welcome-file>
		<welcome-file>index.jsp</welcome-file>
		<welcome-file>default.html</welcome-file>
		<welcome-file>default.htm</welcome-file>
		<welcome-file>default.jsp</welcome-file>
	</welcome-file-list>

	<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>

4.编写Action

package action;

import com.opensymphony.xwork2.ActionSupport;


public class CustomerAction extends ActionSupport {

	/**
	 * 
	 */
	private static final long serialVersionUID = 1L;

	public String save() throws Exception {
		System.out.println("方法执行成功！");
		return SUCCESS;
	}
	
}

5.编写success.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
	<h1>方法执行成功后的页面！</h1>
</body>
</html>

6.配置struts.xml

<!DOCTYPE struts PUBLIC  
    "-//Apache Software Foundation//DTD Struts Configuration 2.5//EN"  
    "http://struts.apache.org/dtds/struts-2.5.dtd">
<struts>
	<!-- <constant name="struts.enable.DynamicMethodInvocation" value="true" 
		/> <constant name="struts.devMode" value="true"></constant> -->
	<package name="demo" namespace="/" extends="struts-default">
		<action name="customerAction_*" class="action.CustomerAction"
			method="{1}">
			<result name="success">success.jsp</result>
		</action>
	</package>
</struts>
