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>
