1、创建web项目
2、添加jar包 （jar包后面连同项目源码一同发布下载链接）
3、配置web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>*.htm</url-pattern>
</filter-mapping>
<welcome-file-list>
<welcome-file>/WEB-INF/html/index.html</welcome-file>
</welcome-file-list>
</web-app>
4、编写请求Action
public class HsunAction extends ActionSupport {
@Override
public String execute() throws Exception {
out.println(msg);
msg = "I am coming ";
out.println(msg);
return SUCCESS;
}
public String test() throws Exception{
msg = "hello test";
out.println("hello test");
return SUCCESS;
}
private String msg;
public String getMsg() {
return msg;
}
public void setMsg(String msg) {
this.msg = msg;
}
}5、配置struts.xml
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd"> <struts> <!--增加struts的扩展名--> <constant name="struts.action.extension" value="htm" /> <package name="hsun" namespace="" extends="struts-default"> <action name="hello" class="com.hsun.struts.action.HsunAction"> <result name="success">/WEB-INF/html/hello.jsp</result> </action> <action name="test" class="com.hsun.struts.action.HsunAction" method="test"> <result name="success">/WEB-INF/html/hello.jsp</result> </action> </package> </struts>
6、返回页面 hello.jsp
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>Home</title>
</head>
<body>
Hello World! <br>
${msg }
</body>
</html>
OK！SUCCESS~~~
项目整体结构如下
