struts2开发环境搭建，环境eclipse + struts 2.5.10 + Tomcat 9
1、eclipse下新建web工程
2、将jar包拷贝到WEB-INF/lib下
3、配置struts.xml 和web.xml【这两个文件可以在下载struts2时struts-2.5.10.1-apps中得到，解压这里面的war包在相应位置能找到，包括这里没有写得log4j2.xml】
struts.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.5//EN"
"http://struts.apache.org/dtds/struts-2.5.dtd">
<struts>
<package name="default" extends="struts-default">
<action name="helloWorld" class="com.marost.action.HelloWorldAction" method="excute">
<result name="success">/WEB-INF/page/hello.jsp</result>
</action>
</package>
</struts>
web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app id="starter" version="2.4"
xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<web-resource-collection>
<web-resource-name>No-JSP</web-resource-name>
<url-pattern>*.jsp</url-pattern>
</web-resource-collection>
<auth-constraint>
<role-name>no-users</role-name>
</auth-constraint>
</security-constraint>
<security-role>
<description>Don‘t assign users to this role</description>
<role-name>no-users</role-name>
</security-role>
</web-app>
4、新建action
package com.marost.action;
public class HelloWorldAction {
private String msg;
public String getMessage() {
return msg;
}
public String excute(){
msg = "你好！";
return "success";
}
}
5、新建jsp
在body中输出action中的内容
<%@ 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>
${message }
</body>
</html>
最终的工程结构如下：
访问：http://localhost:8080/Struts2/helloWorld
