Struts2開發步驟
1.新建web工程Strutsdemo並引入jar包：
commons-fileupload-1.2.1.jar
freemarker-2.3.15.jar
ognl-2.7.3.jar
struts2-core-2.1.8.jar
xwork-core-2.1.6.jar
2.在web.xml中添加控制器配置：
<?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>strutsdemo</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>strutsdemo</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
</web-app> package demo;
public class Test {
private String name;
public String execute(){
name = "hello world";
return "success";
}
public String getName() {
return name;
}
}4.在src下創建struts.xml配置文件：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.1.7//EN"
"http://struts.apache.org/dtds/struts-2.1.7.dtd">
<struts>
<package name = "demo1" extends = "struts-default">
<action name = "welcome" class = "demo.Test">
<result name = "success">hello.jsp</result>
</action>
</package>
</struts>5.創建hello.jsp文件
<html>
<head>
<title>demo</title>
</head>
<body>
${name } <br>
</body>
</html>
6.在瀏覽器地址欄發送請求：
http://127.0.0.1:8888/Strutsdemo/welcome.action
瀏覽器顯示：
hello world
