自己动手写一个java版QQ

基于java实现的仿qq即时通讯工具   数据库使用sql server

项目源码http://git.oschina.net/qrne0607/javaqq  

1. 包分类

ht_功能函数包

• send发送qq信息
• sendMsg消息类

ht.bean

• 三个数据表对应的java bean （java bean不包含数据库操作，仅有成员属性和setget方法）

ht.cmd用到的命令字和常量

• Cmd

ht.db数据库操作包

• DBConn数据库连接
• DBOper数据库操作

ht.ui与界面有关的包

• ChatUI聊天框
• FindUI查找好友框
• Login登录框
• Lookusers查看好友信息
• MainUI主界面框
• RegUsers注册界面

2. 数据表结构

Account:

friend:

3.部分代码

Send.java

package ht_;import java.io.ByteArrayOutputStream;import java.io.ObjectOutputStream;import java.net.DatagramPacket;import java.net.DatagramSocket;import java.net.InetAddress;public class Send {public void send(SendMsg msg){try{//字节数组输出流ByteArrayOutputStream bos=new  ByteArrayOutputStream();ObjectOutputStream oos=new ObjectOutputStream(bos);oos.writeObject(msg);//最终byte[] b=bos.toByteArray();//把要发送的信息转换为字节数组//网络上发送任何东西都是发送字节数组DatagramSocket socket=new DatagramSocket();//UDP通信InetAddress add=InetAddress.getByName(msg.friendAccount.getIpAddr());int port=msg.friendAccount.getPort();DatagramPacket p=new DatagramPacket(b,0,b.length,add,port);//发送 socket.send(p);socket.close();}catch (Exception e){e.printStackTrace();}}}

sendMsg:消息类

package ht_;import ht.bean.Account;import java.io.ByteArrayOutputStream;import java.io.IOException;import java.io.ObjectOutputStream;import java.io.Serializable;import javax.swing.text.StyledDocument;public class SendMsg implements Serializable{public int Cmd;//命令字public Account selfAccount,friendAccount;//自己的信息,对方的信息public StyledDocument doc;public String sFileName;public byte[] b;}

java bean，以Account为例

package ht.bean;import java.io.Serializable;//对应Account表，一个字段对应一个成员变量public class Account implements Serializable{private int qqCode;private String nickName;private String pwd;private String ipAddr;private int port;private int age;private String sex;private String nation;private String star;private String face;private String remark;private String selfsign;private int status;//0离线 1在线 2隐身 3 忙碌private String groupname;public String getGroupname() {return groupname;}public void setGroupname(String groupname) {this.groupname = groupname;}public int getStatus() {return status;}public void setStatus(int status) {this.status = status;}public int getQqCode() {return qqCode;}public void setQqCode(int qqCode) {this.qqCode = qqCode;}public String getNickName() {return nickName;}public void setNickName(String nickName) {this.nickName = nickName;}public String getPwd() {return pwd;}public void setPwd(String pwd) {this.pwd = pwd;}public String getIpAddr() {return ipAddr;}public void setIpAddr(String ipAddr) {this.ipAddr = ipAddr;}public int getPort() {return port;}public void setPort(int port) {this.port = port;}public int getAge() {return age;}public void setAge(int age) {this.age = age;}public String getSex() {return sex;}public void setSex(String sex) {this.sex = sex;}public String getNation() {return nation;}public void setNation(String nation) {this.nation = nation;}public String getStar() {return star;}public void setStar(String star) {this.star = star;}public String getFace() {return face;}public void setFace(String face) {this.face = face;}public String getRemark() {return remark;}public void setRemark(String remark) {this.remark = remark;}public String getSelfsign() {return selfsign;}public void setSelfsign(String selfsign) {this.selfsign = selfsign;}}

命令字和常量Cmd.java

package ht.cmd;//系统中要用到的命令字，常量public class Cmd {public static final int CMD_ONLINE=1000;//上线通知public static final int CMD_OFFLINE=1001;//下线通知public static final int CMD_BUSY=1002;//忙碌public static final int CMD_LEAVE=1003;//离开public static final int CMD_CHAT=1004;//聊天public static final int CMD_DOUDONG=1005;//抖动public static final int CMD_ADDFRIEND=1006;//添加好友public static final int CMD_DELFRIEND=1007;//删除好友public static final int CMD_SENDFILE=1008;//发送文件public static final int CMD_AFREEFRIEND=1009;//发送文件public static final int CMD_REJECTFRIEND=1010;//发送文件public static final int CMD_FILESUCC=1011;//文件发送成功public static final int CMD_FILEFAILED=1012;//拒绝接收文件public static final int CMD_FILESEND=1013;//文件发送public static final String F_FRIEND="好友";public static final String F_FAMILY="家人";public static final String F_CLASSMATE="同学";public static final String F_HMD="黑名单";}

连接数据库：DBconn.java

package ht.db;import java.sql.Connection;import java.sql.DriverManager;//这类仅仅负责调入驱动程序 并且连接数据库 其他功能都在库同名javaBean里写public class DBConn {//使用传统方法jdbcdriver连接数据库//static String url="jdbc:sqlserver://localhost:1433;databasename=QQ";//连接数据库的字符串  localhost可以写ip(一般服务器)或者机器名, 1433是数据库默认端口//static String driver="com.microsoft.sqlserver.jdbc.SQLServerDriver";//驱动程序;//使用JDBC-ODBC桥连方式操作数据库static String url="jdbc:odbc:LocalServer";//连接数据源  数据源名称是LocalServerstatic String driver="sun.jdbc.odbc.JdbcOdbcDriver";//驱动程序;static Connection conn=null;//静态语句块 负责调入驱动 整个程序只需要调用一次static{try {Class.forName(driver);}catch(ClassNotFoundException e){e.printStackTrace();}}//构造函数 用来连接数据库public Connection DBConn(){try{//2.连接数据库conn=DriverManager.getConnection(url);System.out.println("数据库连接成功。。。");}catch(Exception e){e.printStackTrace();}return conn;}}

数据库操作:DBConn.java
