在Web工程项目中使用Struts
摘要: Web应用开发,在Web工程项目中使用Struts。
起初的工程（未引入Struts）目录结构如下： 用户： 密码： 标题: 内容: 作者:
修改你的web.xml配置
如下：
修改之前是：
<?xml version="1.0" encoding="UTF-8"?>
web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application
2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">
加入：
Action Servlet Configuration 标准Struts Action Servlet 配置
引入Struts所需的标签库
引入目录结构如下：（配置文件描述）
在工程中引入Struts工程所需的.jar文件
目录结构如下：
引入资源文件：
ApplicationResources.properties
内容如下：
# -- buttons --button.submit=Submitbutton.cancel=Cancelbutton.confirm=Confirmbutton.reset=Resetbutton.save=Save
现在编写一个测试代码：
编写一个提交数据库的表单jsp文件useStruts.jsp：
如下：
html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><%@
page language="java" contentType="text/html;
charset=utf-8" %><%@ taglib url="/WEB-INF/struts-html.tld"
prefix="html" %><%@ taglib url="/WEB-INF/struts-bean.tld"
prefix="bean" %>
<form-bean name="usestrutsForm" type="org.apache.struts.action.DynaActionForm">
<form-property name="user" type="java.lang.String"
/>
<form-property name="password" type="java.lang.String"
/>
<form-property name="title" type="java.lang.String"
/>
<form-property name="content" type=" java.lang.String
" />
<form-property name="author" type="java.lang.String"
/>
</form-bean>
</form-beans>
=============================
name="usestrutsForm"
scope="request"
input="/jsp/useStruts.jsp"
validate="true">
创建两个Action：
preUsestrutsAction.java 、ProcessUseStrutsAction.java
preUsestrutsAction.java:
代码如下：
