学习struts 1x 配置

一 、配置:
1.拷贝struts1x/lib下所有jar包至所建项目WebContent/WEB-INF/lib/
2.将struts/webapps\struts-blank\WEB-INF\web.xml中内容拷贝到项目web.xml,即配置ActionServlet
3.将struts/webapps\struts-blank\WEB-INF\struts-config.xml文件拷贝到项目WebContent/WEB-INF/
二、创建项目
1.创建jsp页面（login.jsp,login_success.jsp,login_error.jsp）
2.建src/LoginActionForm.java继承org.apache.struts.action.ActionForm是用于数据收集的,其属性必须与页面中name一致,生成get和set方法
3.建src/LoginAction.java继承org.apache.struts.action.Action
     并重写execute(ActionMapping mapping, ActionForm form,HttpServletRequest request, HttpServletResponse response)方法,
     将传过来的form强制转换成TestActionForm用get方法进行取值,调用模型层进行处理（连数据库比较等）,进行转向
4.配置struts-config.xml

 

web.xml:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">

struts-config.xml:

<!DOCTYPE struts-config PUBLIC

LoginAction.java

package com.ht.action;
