1.新建Web项目在lib导入struts-2.3.37核心基础jar包
2.在WebRoot新建2个JSP
demo1.jsp
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head> <title>Struts2入门</title>
</head> <body>
<h1>Struts入门</h1>
<a href="${pageContext.request.contextPath }/strutsDemo1.action">访问Struts的action</a>
</body>
</html>
demo2.jsp
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head> </head> <body>
<h1>跳转成功！</h1>
</body>
</html>
3.在项目中的web.xml中添加代码
<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>/*</url-pattern>
</filter-mapping>
4.建包建类
package com.sve.struts2;
public class Demo1 {
public String execute() {
System.out.println("方法执行了");
return "success";
}
}
注意：方法名必须为execute，返回值必须为String，且public
5.在src下创建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> <package name="demo" namespace="/" extends="struts-default">
<action name="strutsDemo1" class="com.sve.struts2.Demo1">
<result name="success">/demo2.jsp</result>
</action>
</package>
</struts>
在action中class为你建包名.类名，name为demo1.jsp中访问链接，无须加.action
在result中，name的值为类中的返回值
