起初的工程(未引入Struts)目录结构如下:
修改你的web.xml配置
如下:
修改之前是:
<?xml version="1.0" encoding="UTF-8"?>
<!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>
<!-- The mapping for the default servlet -->
<servlet>
<servlet-name>estservlet</servlet-name>
<servlet-class>action.JDBCServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>estservlet</servlet-name>
<url-pattern>/estservlet</url-pattern>
</servlet-mapping>
<servlet>
<servlet-name>delconad</servlet-name>
<servlet-class>action.delConadBean</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>delconad</servlet-name>
<url-pattern>/delconad</url-pattern>
</servlet-mapping>
</web-app>
加入:
<!-- import Struts MVC framework-->

</taglib>
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=Submit
button.cancel=Cancel
button.confirm=Confirm
button.reset=Reset
button.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:
<!DOCTYPE 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" %>
<html:html xhtml="true" locale="true">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>使用 Struts DynaActionForm 插入Mysql数据库</title>
<html:base/>
<link rel="stylesheet" type="text/css" href="../css/example.css" />
</head>
<body>
<html:errors/>
<html:form action="/insertmysql.do">
<p>用户:<br/>
<html:text property="user" size="40" maxlength="20"/></p>
<p>密码:<br/>
<html:text property="password" size="40" maxlength="20"/></p>
<p>标题:<br/>
<html:text property="title" size="40" maxlength="50"/></p>
<p>内容:<br/>
<html:text property="content" size="40" maxlength="50"/></p>
<p>作者:<br/>
<html:text property="author" size="40" maxlength="50"/></p>
</html:form>
</body>
</html:html>
修改Struts-config.xml文件:
<form-beans>
<!-- DynaActionForm Bean for usesturts -->
<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>
<!-- ========== Action Mapping Definitions ============================= -->
<action-mappings>
<!-- usersturts ActionForm ===================================== -->
<action path="/prepareUsestruts"
type="action.preUsestrutsAction">
<forward name="success" path="/jsp/useStruts.jsp"/>
</action>
<action path="/processUsestruts"
type="action.ProcessUseStrutsAction"
name="usestrutsForm"
scope="request"
input="/jsp/useStruts.jsp"
validate="true">
<forward name="success" path="/jsp/useStruts.jsp"/>
</action>
</action-mappings>
创建两个Action:
preUsestrutsAction.java 、ProcessUseStrutsAction.java
preUsestrutsAction.java:
代码如下:

测试成功!
可以借鉴一下!成功!(参考附件)
