Flex与Java基于RemoteObject进行数据库（mysql）操作

首先呢，一些基本配置这里就不作一一介绍了（可以去网上查查 很多的配置视频、文档，这里只是代码）

 

1）建立一个Java+Flex工程

 

2）新建java类

 

  1.AddDataImpl.java

 

 

package com;
import java.sql.*;
import com.ConnectionFactory;
public class AddDataImpl { 
 String sql;  // 定义类型
 Connection conn = null;
 Statement stmt = null;
 int rs; 
 public AddDataImpl(){} 
 public NoticeInfo[] addData(){  
   try{
    conn = ConnectionFactory.getConnection();
    stmt = conn.createStatement(); 
    String sql = "insert into userinfo values ('11','11','11','1111-11-11') ";
    rs=stmt.executeUpdate(sql);
    stmt.close();    
   }catch(SQLException e){
    e.printStackTrace(); 
   }
 return null;
 } 
}

 

2.ConnectionFactory.java

 

package com;

import java.sql.*; 
 
public class ConnectionFactory {
 private static ConnectionFactory ref = new ConnectionFactory();
  // 连接mysql数据库， database : test  user : root  password : 1272107226
  private ConnectionFactory()
  {
   try{
    Class.forName("com.mysql.jdbc.Driver");
   }catch(ClassNotFoundException e)
   {
    System.out.println("ERROR: exception loading driver class");
   }
  }
  public static Connection getConnection() throws SQLException{
   
   String url = new String ("jdbc:mysql://localhost:3306/test?user=root&password=root");
   return DriverManager.getConnection(url);
  }
  
  public static void close(ResultSet rs)
  {
   try{
    rs.close();
   }catch(Exception ignored){}
  }
  public static void close(Statement stmt)
  {
   try{
    stmt.close();
   }catch(Exception ignored){}
  }
  public static void close(Connection conn)
  {
   try{
    conn.close();
   }catch(Exception ignored){}
  }   
}

 3.DataServiceImpl.java

 

package com;

import java.sql.*;
import java.util.ArrayList;

import com.ConnectionFactory;

public class DataServiceImpl {
 String sql;  // 定义类型
 Connection conn = null;
 Statement stmt = null;
 ResultSet rs = null;  
 public DataServiceImpl(){}
 public NoticeInfo[] getNotices(){	  
	  ArrayList noticeList = new ArrayList();	  
	  try{
	   conn = ConnectionFactory.getConnection();
	   stmt = conn.createStatement(); 	   
	   String sql = "select userid, username, contents, dates from userinfo ";
	   rs = stmt.executeQuery(sql);	  	   
	   while(rs.next()){	    
	    NoticeInfo temp = new NoticeInfo(); 
	    temp.setUserid(rs.getString("userid"));
	    temp.setUsername(rs.getString("username"));
	    temp.setContents(rs.getString("contents"));
	    temp.setDates(rs.getString("dates"));
	    
	    noticeList.add(temp);	    
	   }	   
	   NoticeInfo[] notices = new NoticeInfo[noticeList.size()];
	   for(int i=0;i < noticeList.size();i++){
	    notices[i] = (NoticeInfo) noticeList.get(i);    
	   }
	   return notices;
	  }catch(SQLException e){
	   e.printStackTrace();
	   return null;
	  }
	 }
}

 4.NoticeInfo.java

 

package com;

public class NoticeInfo {
	
	 private String userid;
	 private String username;
	 private String contents;
	 private String dates;
	 
	 
	 public String getContents() {
	  return contents;
	 }
	 public void setContents(String contents) {
	  this.contents = contents;
	 }
	 public String getDates() {
	  return dates;
	 }
	 public void setDates(String dates) {
	  this.dates = dates;
	 }
	 
	 
	 public String getUserid() {
	  return userid;
	 }
	 public void setUserid(String userid) {
	  this.userid = userid;
	 }
	 public String getUsername() {
	  return username;
	 }
	 public void setUsername(String username) {
	  this.username = username;
	 }

}

 

 

 

3）新建Flex页面

 

1.  AddDataText.mxml

 

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" fontSize="12" creationComplete="initApp()">
 <mx:Script>
  <![CDATA[
   import mx.controls.Alert;
   import mx.utils.ArrayUtil;
   
   private function initApp():void
   {
   	addDataId.addData();
   }
   

  ]]>
 </mx:Script>
 
 <mx:RemoteObject id="addDataId" destination="addData"/>
 <mx:Button label="插入数据" click="initApp()"/>
 
</mx:Application>

 

2.  JavaMysql.mxml

  

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" fontSize="12" creationComplete="initApp()">
 <mx:Script>
  <![CDATA[
   import mx.controls.Alert;
   import mx.utils.ArrayUtil;
   
   private function initApp():void
   {
        getData.getNotices();
   
   }
   
   private function proccessResult(result:Object):void
   {
        myDG.dataProvider = ArrayUtil.toArray(result);
   } 
   private function addDataFunction():void
   {
     	addDataId.addData();
   }
  ]]>
 </mx:Script>
 
  <mx:RemoteObject id="getData" destination="dataService" result="proccessResult(event.result)" fault="Alert.show(event.fault.faultString,'Error')"/>
  <mx:RemoteObject id="addDataId" destination="addData"/>
  <mx:Button label="插入数据" click="addDataFunction()" x="373" y="299"/>
 
   <mx:DataGrid id="myDG" x="236" y="103">
        <mx:columns>
         <mx:DataGridColumn headerText="id" dataField="userid"/>
            <mx:DataGridColumn headerText="username" dataField="username"/>
            <mx:DataGridColumn headerText="contents" dataField="contents"/>
            <mx:DataGridColumn headerText="dates" dataField="dates"/>
        </mx:columns>
    </mx:DataGrid> 

</mx:Application>

4）配置remoting-config.xml

 

<?xml version="1.0" encoding="UTF-8"?>
<service id="remoting-service" 
    class="flex.messaging.services.RemotingService">

    <adapters>
        <adapter-definition id="java-object" class="flex.messaging.services.remoting.adapters.JavaAdapter" default="true"/>
    </adapters>

    <default-channels>
        <channel ref="my-amf"/>
    </default-channels>

    <destination id="dataService">
       <properties>
          <source>com.DataServiceImpl</source>
       </properties>
    </destination>
    
    <destination id="addData">
       <properties>
          <source>com.AddDataImpl</source>
       </properties>
    </destination>
    
</service>

  

5)创建数据库

 

DROP DATABASE IF EXISTS `test`;
CREATE DATABASE `test` /*!40100 DEFAULT CHARACTER SET utf8 */;
USE `test`;
CREATE TABLE `userinfo` (
  `userid` int(11) NOT NULL auto_increment,
  `username` varchar(20) default NULL,
  `contents` varchar(20) default NULL,
  `dates` date default NULL,
  PRIMARY KEY  (`userid`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

INSERT INTO `userinfo` VALUES (1,'as','as','2010-05-03');
INSERT INTO `userinfo` VALUES (2,'admin','wo','2010-10-12');
INSERT INTO `userinfo` VALUES (3,'admin3','wo','2010-10-12');
INSERT INTO `userinfo` VALUES (4,'admin4','wo','2010-10-12');
INSERT INTO `userinfo` VALUES (5,'admin5','wo','2010-10-12');
INSERT INTO `userinfo` VALUES (6,'admin6','wo','2010-10-12');
INSERT INTO `userinfo` VALUES (7,'admin7','wo','2010-10-12');
INSERT INTO `userinfo` VALUES (8,'admin8','wo','2010-10-12');
INSERT INTO `userinfo` VALUES (9,'admin9','wo','2010-10-12');
INSERT INTO `userinfo` VALUES (10,'admin10','wo','2011-11-11');

 

6）引进 连接mysql的包

 

名字为：mysql-connector-java-5.1.7-bin.jar

 

最后调试，一般都能成功，要还是不能成功的请发邮箱：[email protected]
