　　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"
         xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

  <display-name>Struts 2 Rest Example</display-name>


  <!-- Filters -->
  <!-- START SNIPPET: filter -->
    <filter>
        <filter-name>action2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class>
    </filter>
    <!-- END SNIPPET: filter -->

    <filter-mapping>
        <filter-name>action2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <!-- Welcome file lists -->
    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>

    <!-- Restricts access to pure JSP files - access available only via Struts action -->
    <security-constraint>
        <display-name>No direct JSP access</display-name>
        <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：
