一、创建控制层
（1）创建VO值对象，对应页面表单的属性值
package com.cppdy.ssh.web.form;
/**
* VO值对象，对应页面表单的属性值
* VO对象与PO对象的关系：
* 相同点：都是javabean
* 不同点：PO对象中的属性关联数据库的字段
* VO对象中的属性可以随意增加、修改、删除，对应的页面表单属性
*
*/
@SuppressWarnings("serial")
public class ElecTextForm implements java.io.Serializable {
private String textID;
private String textName;
private String textDate;
private String textRemark;
public String getTextID() {
return textID;
}
public void setTextID(String textID) {
this.textID = textID;
}
public String getTextName() {
return textName;
}
public void setTextName(String textName) {
this.textName = textName;
}
public String getTextDate() {
return textDate;
}
public void setTextDate(String textDate) {
this.textDate = textDate;
}
public String getTextRemark() {
return textRemark;
}
public void setTextRemark(String textRemark) {
this.textRemark = textRemark;
}
}
ElecTextForm.java
（2）创建action类，继承ActionSupport类，实现驱动类ModelDriven
package com.cppdy.ssh.web.action;
import com.cppdy.ssh.web.form.ElecTextForm;
import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ModelDriven;
@SuppressWarnings("serial")
public class ElecTextAction extends ActionSupport implements ModelDriven<ElecTextForm>{
private ElecTextForm elecTextForm = new ElecTextForm();
public ElecTextForm getModel() {
return elecTextForm;
}
public String save(){
System.out.println(elecTextForm.getTextName());
return "save";
}
}
ElecTextAction.java
二、创建struts.xml配置
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.1.7//EN"
"http://struts.apache.org/dtds/struts-2.1.7.dtd">
<struts>
<!-- 配置action的访问路径为.do的形式 -->
<constant name="struts.action.extension" value="do"></constant>
<!-- 配置struts的开发模式 -->
<constant name="struts.devMode" value="true"></constant>
<!-- 配置struts的简单模式 -->
<constant name="struts.ui.theme" value="simple"></constant>
<package name="system" namespace="/system" extends="struts-default">
<action name="elecTextAction_*" class="com.cppdy.ssh.web.action.ElecTextAction" method="{1}">
<result name="save">
/system/textAdd.jsp
</result>
</action>
</package>
</struts>
struts.xml
三、添加struts过滤器（web.xml）
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.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>
web.xml
四、添加jsp页面
（1）index.jsp添加连接地址
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">
<title>My JSP ‘index.jsp‘ starting page</title>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">
</head>
<body>
<a href="<%=basePath%>system/textAdd.jsp">测试添加功能</a>
</body>
</html>
index.jsp
（2）添加功能测试页面
<%@ page language="java" pageEncoding="UTF-8"%>
<html>
<head>
<title>测试专用jsp</title>
<script language="javascript">
function checkchar(){
document.Form1.action="elecTextAction_save.do";
document.Form1.submit();
alert(" 保存成功!");
}
function addEnter(element){
document.getElementById(element).value = document.getElementById(element).value+"<br>";
}
</script>
</head>
<body>
<form name="Form1" id="Form1" method=post>
<table cellspacing="1" cellpadding="5" width="90%" align="center" bgcolor="#f5fafe" style="border:1px solid #8ba7e3" border="0">
<tr>
<td class="ta_01" colspan=2 align="center" background="${pageContext.request.contextPath }/images/b-info.gif">
<font face="宋体" size="2">
<strong>测试专用jsp</strong>
</font>
</td>
</tr>
<TR height=10><td></td><td></td></TR>
<tr>
<td class="ta_01" align="center" bgcolor="#f5fafe" width="15%">测试名称：</td>
<td class="ta_01" bgcolor="#ffffff" style="word-break: break-all">
<textarea name="textName" id="textName" style="width: 500px; height: 160px; padding: 1;FONT-FAMILY: 宋体; FONT-SIZE: 9pt" onkeydown="if(event.keyCode==13)addEnter(‘textName‘);"></textarea>
</td>
</tr>
<tr>
<td class="ta_01" style="width: 100%" align="center" bgcolor="#f5fafe" colspan="2">
<input type="button" name="BT_Submit" value="保存" onclick="checkchar()" id="BT_Submit" style="font-size:12px; color:black; height=20;width=50">
</td>
</tr>
</table>
</form>
</body>
</html>
textAdd.jsp
五、发布web项目
六、启动项目
七：访问项目（http://localhost:8080/ssh/）
八、添加数据，点击保存
九、查看控制台打印jsp添加的数据
十、项目结构
