flash+struts的小应用

前言：原创，实现flash结合struts框架的一个小应用。

============================================================================================

一、开发环境：

1、elcipse3.2+myEclipse5.5；Tomcat5.5；数据库用的是ORACL9i（用什么数据库都可以）

2、flash8+as2.0；struts1.2.9

原理分析：先空着回来补上，今天写不完。。

二、开发步骤：

1、配置环境：在eclipse中先建立一个web projecet，将struts需要的jar文件加入到WEB-INF/lib中

      jar文件的列表：关于这些包的取得，可以到网上查一下，都可轻松找到。

antlr.jar
commons-beanutils.jar
commons-digester.jar
commons-fileupload.jar
commons-logging.jar
commons-validator.jar
jakarta-oro.jar
jdom.jar
mysql-connector-java-5.0.3-bin.jar
ojdbc14.jar
struts.jar

2、配置好WEB-INF中web.xml；

<!---->xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.4" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee   http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
  <servlet>
    <servlet-name>actionservlet-name>
    <servlet-class>org.apache.struts.action.ActionServletservlet-class>
    <init-param>
      <param-name>configparam-name>
      <param-value>/WEB-INF/struts-config.xmlparam-value>
    init-param>
    <init-param>
      <param-name>debugparam-name>
      <param-value>3param-value>
    init-param>
    <init-param>
      <param-name>detailparam-name>
      <param-value>3param-value>
    init-param>
    <load-on-startup>0load-on-startup>
  servlet>
  <servlet-mapping>
    <servlet-name>actionservlet-name>
    <url-pattern>*.dourl-pattern>
  servlet-mapping>
web-app>

3、在WEB-INF中创建struts-config.xml

<!---->xml version="1.0" encoding="UTF-8"?>
<!---->>

<struts-config>
  <data-sources />
  <form-beans >
    <form-bean name="DomainNameAcionForm" type="com.test.actionforms.DomainNameActionForm" />

  form-beans>

  <global-exceptions />
  <global-forwards />
  <action-mappings >
    <action
      path="/PlaceQueryAction"
      type="com.test.actions.PlaceQueryAction"
      validate="false"/>
    <action
      path="/Index"
      type="com.test.actions.Index"
      validate="false">
      <forward name="ok" path="/jsps/index.jsp" />
    action>
    <action
      attribute="DomainNameActionForm"
      input="/jsps/showInfo.jsp"
      name="DomainNameAcionForm"
      path="/DomainNameAcion"
      scope="request"
      type="com.test.actions.DomainNameAcion"
      validate="true">
      <forward name="ok" path="/jsps/showInfo.jsp" />
    action>

  action-mappings>

  <message-resources parameter="com.test.actions.ApplicationResources" />
struts-config>

4、依照struts的规则，创建action，还好，应用很小，只是个示例程序，都能看懂。

com.test.actions.PlaceQueryAction代码

package com.test.actions;
/*
 * Generated by MyEclipse Struts
 * Template path: templates/java/JavaClass.vtl
 */
import java.io.IOException;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;

import com.test.dao.DataAccessDao;
import com.test.util.Constants;

/**
 * MyEclipse Struts
 * Creation date: 07-11-2007
 *
 * XDoclet definition:
 * @struts.action
 * @struts.action-forward name="ok" path="/jsps/index.jsp" contextRelative="true"
 */
public class PlaceQueryAction extends Action {
    /*
     * Generated Methods
     */

    /**
     * Method execute
     * @param mapping
     * @param form
     * @param request
     * @param response
     * @return ActionForward
     */
    public ActionForward execute(ActionMapping mapping, ActionForm form,
            HttpServletRequest request, HttpServletResponse response) {

        //test
        //System.out.println("PlaceQueryAction**************************************************************************************************");

        // TODO Auto-generated method stub
        response.setCharacterEncoding("utf-8");
        response.setContentType("txt/html");
         //获得查询参数
        String queryArea = request.getParameter("queryArea");//查询的地区
        String projectname=request.getContextPath();
        Constants.projectname=projectname.substring(1, projectname.length());
        //设置查询条件
        DataAccessDao dataQuery = new DataAccessDao();
        if(dataQuery.rebuldData(queryArea))
        {
            try{
                response.getWriter().write("&OK=0&reason=");//查询成功返回0
            }catch(IOException e)
            {
                System.err.println("******1response writeback error!******");
                e.printStackTrace();
            }
        }else
        {
            try{
                response.getWriter().write("&OK=1&reason=生成XML出错!");//查询失败返回1
            }catch(IOException e)
            {
                System.err.println("******2response writeback error!******");
                e.printStackTrace();
            }
        }
        return null;
    }
}

5、创建actionform，哦对了，不需要，继续...连接数据库。。

DataAccessDao.java 代码

/*需要什么包就自己加，限于篇幅这里没加，SysReportHelper类与本系统没太大关系，就是一个存储数据的对象，这里没有创建，这些代码都能看懂，不用多说了吧。。
*/
public class DataAccessDao {
    /**
     * @param PlaceData
     * @return ArrayList
     */
    public ArrayList<sysreporthelper></sysreporthelper> getData(String app) {
        Connection connection =getDBConnection(Constants.MYSQL_DRIVER,Constants.MYSQL_URL,
                   Constants.MYSQL_USER_NAME,Constants.MYSQL_PASSWORD);
        Statement statement=null;
        ArrayList<sysreporthelper></sysreporthelper> pList = new ArrayList<sysreporthelper></sysreporthelper>();

        ResultSet resultSet = null;
        String sql = null;
        if (app != null && app.equals(Constants.DIS_APPROVED)) {
            sql = "SELECT * FROM sysreport";
        } else if (app != null && app.equals(Constants.APPROVED)) {
            sql = "SELECT * FROM statreport_p";
        }
        try {
            statement = connection.createStatement();
            resultSet = statement.executeQuery(sql);
            // 读出数据
            while (resultSet.next()) {
                data.setZhuhai(resultSet.getString("ZH"));
                pList.add(data);
            }

        } catch (SQLException e) {
            System.err.print("*****SQLException:query error(执行查询出错)*****");
            e.printStackTrace();
        }finally
        {
            try{
                resultSet.close();
                statement.close();
                connection.close();
            }
            catch(SQLException e)
            {
                e.printStackTrace();
            }
        }
        return pList;
    }
/**
     *
     * @return Connection
     */
    private Connection getDBConnection(String driver,String url,String username,String pwd) {
        Connection connection = null;
        // 连接DB
        try {
            Class.forName(driver);
            connection = DriverManager.getConnection(url,username, pwd);
        } catch (SQLException e) {
            System.err.println("******unable to connect database!(无法连接数据库)******");
            e.printStackTrace();
        } catch (ClassNotFoundException e) {
            System.err.println("******fail to load JDBC/ODBC(加载JDBC/ODBC失败)*******");
            e.printStackTrace();
        }
        return connection;
    }
}

 6、创建个index.jsp把flash动画嵌进去。。注意代码里面的两个javascript函数，现在用不到，我没有删。

index.jsp代码

<%@ page language="java" pageEncoding="UTF-8"%>
<%@ page contentType="text/html; charset=UTF-8" %>
<html>
  <head>
    <meta http-equiv="Content-Type" content="text/html;charset=UTF-8">
    <title>Flash page</title>
</head>
  <body>
    <table>
      <tr>
        <td>
          <object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,29,0" width="550" height="400">
            <param name="movie" value="<%=request.getContextPath()%>/swfs/ChinaMap/main.swf">
               <param name="quality" value="high"/>
               <embed src="<%=request.getContextPath()%>/swfs/ChinaMap/main.swf" quality="high" pluginspage="http://www.macromedia.com/go/getflashplayer" type="application/x-shockwave-flash" width="550" height="400"></embed>
          </object>
        </td>
        <td>
           <iframe id="right_ifr" src="<%=request.getContextPath()%>/jsps/showInfo.jsp" frameBorder=0
                   width=410 scrolling=yes height=500>
           </iframe>
          </td>
      </tr>
  </table>
  </body>
</html>

7、开始创建flash动画，动画名称要和JSP中的一致，这里取名main.swf，大家可以自己做个按钮和一个textfield做测试即可。在按钮按下时，触发以下动作：

     （由于代码属于一个项目不能全贴出来，只能拿关键部分贴出来，所以有些跳跃，不过思路是正确的。）

ActionScript代码

function loadInfo(queryArea)
{
    var loadcom = new LoadVars();
    //STRUTS 2.0
    //var temp="com/test/actions/getData.action?queryArea=";
    //Struts 1.2.9
    var temp="PlaceQueryAction.do?queryArea=";
    var queryStr=_root.projecturl+temp+queryArea+"&randNum="+Math.random(1)*100;
    _root.loadinfos.text="查询...";
    loadcom.sendAndLoad(queryStr, loadcom, "post");
    loadcom.onLoad = function(OK) {
    if (OK)
    {
        if(loadcom.OK==0)
        {
            if(loadIndata(queryArea))
            {
                _root.Maps.gotoAndPlay("ShowMap");
            }else
            {
                _root.loadinfos.text="无法加载XML!";
            }
        }else if(loadcom.OK==1)
        {
            _root.loadinfos.text="内部错误："+loadcom.reason;
        }
    } else {
    //输出文本内容
    _root.loadinfos.text="通讯失败：无法连接服务器！";
    textformat.color=errorcolor;
    _root.loadinfos.setTextFormat(textformat);
    }
  }
};

好了，基本上就可以测试了，嘿嘿，写的简单了点。慢慢把条理整清楚。。。
