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"
