Struts2的Hello World!
1.用MyEclipse New一个Web Project:struts2
2.在http://people.apache.org/builds/struts/上下载所需的包
然后在WebRoot/WEB-INF导入Struts2的包:
commons-logging-1.0.4.jar
freemarker-2.3.4.jar
junit-3.8.1.jar
ognl-2.6.7.jar
oscore-2.2.4.jar
struts2-api-2.0.0-SNAPSHOT.jar
struts2-core-2.0.0-SNAPSHOT.jar
struts2-extras-2.0.0-SNAPSHOT.jar
xwork-2.0.0-SNAPSHOT.jar
3.在src/com/test下建立TestAction.java类:
4.在src下建立struts.xml跟struts.properties文件:
struts.xml:
struts.properties:（暂时不用，可以先清空即可）
5.在WebRoot/WEB-INF下建立web.xml文件:
6.在WebRoot/WEB-INF下建立test.jsp跟success.jsp：
test.jsp:
success.jsp:
2.在http://people.apache.org/builds/struts/上下载所需的包
然后在WebRoot/WEB-INF导入Struts2的包:
commons-logging-1.0.4.jar
freemarker-2.3.4.jar
junit-3.8.1.jar
ognl-2.6.7.jar
oscore-2.2.4.jar
struts2-api-2.0.0-SNAPSHOT.jar
struts2-core-2.0.0-SNAPSHOT.jar
struts2-extras-2.0.0-SNAPSHOT.jar
xwork-2.0.0-SNAPSHOT.jar
3.在src/com/test下建立TestAction.java类:
package com.test;
import com.opensymphony.xwork2.ActionSupport;
@SuppressWarnings("serial")
public class TestAction extends ActionSupport {
//跟页面上的属性对应(FormBean)
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
/***
* Struts2中已定义好静态变量
* SUCCESS = "success"
* NONE = "none"
* ERROR = "error"
* INPUT = "input"
* LOGIN = "login"
* @return
*/
public String skipPage(){
return SUCCESS;
}
}
4.在src下建立struts.xml跟struts.properties文件:
struts.xml:
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<!-- 先加载Struts2-core-2.0.0-SNAPSHOT.jar中的struts-default.xml文件 -->
<include file="struts-default.xml" />
<!-- 继承Struts-core.jar中的配置文件 -->
<package name="default" extends="struts-default">
<!-- 加载具体的Action类的业务方法skipPage,test.action为链接 -->
<action name="test" class="com.test.TestAction" method="skipPage">
<!-- 由type来指定FreeMaker模板、Velocity模板、JasperReports和使用XSL转换等。 -->
<result name="success" type="">/success.jsp</result>
</action>
</package>
</struts>
struts.properties:（暂时不用，可以先清空即可）
5.在WebRoot/WEB-INF下建立web.xml文件:
<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <filter> <filter-name>struts2</filter-name> <filter-class> org.apache.struts2.dispatcher.FilterDispatcher </filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app>
6.在WebRoot/WEB-INF下建立test.jsp跟success.jsp：
test.jsp:
<%@ page language="java" import="java.util.*" pageEncoding="GBK"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<html>
<body>
<s:form action="test">
<s:textfield label="请输入名称" name="name"/>
<s:submit />
</s:form>
</body>
</html>
success.jsp:
<%@ page contentType="text/html; charset=GBK"%> <%@ taglib prefix="s" uri="/struts-tags"%> <html> <body> <s:property value="name"/>跳转到正确页面. </body> </html>
