用idea搭建struts2.5
一.STRUTS介紹
二.搭建環境(使用INTELLIJ IDEA+MAVEN+STRUTS2)
1.建立MAVEN+STRUTS2專案
2.新增配置檔案,自動下載必要JAR包
commons-fileupload-1.2.2.jar 【檔案上傳相關包】
commons-io-2.0.1.jar
struts2-core-2.3.4.1.jar 【struts2核心功能包】
ognl-3.0.5.jar 【Ognl表示式功能支援表】
commons-lang3-3.1.jar 【struts對java.lang包的擴充套件】
freemarker-2.3.19.jar 【struts的標籤模板庫jar檔案】
javassist-3.11.0.GA.jar 【struts對位元組碼的處理相關jar】
配置檔案引入
<dependency>
<groupId>org.apache.struts</groupId>
<artifactId>struts2-core</artifactId>
<version>2.5.10.1</version>
</dependency>
3.WEB.XML中引入STRUTS核心功能——配置過濾器
<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd" >
<web-app>
<display-name>Archetype Created Web Application</display-name>
<!--引入核心過濾器-->
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter >
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>
4.開發ACTION
LoginAction.java
package com.huan.struts.action;
/**
* Created by 馬歡歡 on 2017/6/19.
*/
public class LoginAction {
public String success(){
System.out.println("成功訪問action,請求正在處理中");
System.out.println("呼叫service");
return "success";
}
}
success.jsp
<%--

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>success成功跳轉到該頁面</title>
</head>
<body>
</body>
</html>
5.配置ACTION——SRC/STRUTS.XML
struts2.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="null" extends="struts-default">
<action name="login" class="com.huan.struts.action.LoginAction" method="success">
<result name="success">success.jsp</result>
</action>
</package>
</struts>
1.建立MAVEN+STRUTS2專案步驟:
1).建立Maven專案:maven快速入門
2).設定Groupld和Artfactld名稱
2.新增配置檔案,自動下載必要JAR包
commons-fileupload-1.2.2.jar 【檔案上傳相關包】
commons-io-2.0.1.jar
struts2-core-2.3.4.1.jar 【struts2核心功能包】
ognl-3.0.5.jar 【Ognl表示式功能支援表】
commons-lang3-3.1.jar 【struts對java.lang包的擴充套件】
freemarker-2.3.19.jar 【struts的標籤模板庫jar檔案】
javassist-3.11.0.GA.jar 【struts對位元組碼的處理相關jar】
配置檔案引入
pom.xml
<dependency>
<groupId>org.apache.struts</groupId>
<artifactId>struts2-core</artifactId>
<version>2.5.10.1</version>
</dependency>
