Java基于Swing和netty实现仿QQ界面聊天小项目

1.前言

先说一下这个小项目也算是我在大学做的第一个应该算的上是的项目的项目,前前后后用了20天左右吧。先是用swing写好了仿QQ界面(界面很丑)最后逻辑实现都是后面断断续续加进去的。写这个项目之前没有很好的规划在逻辑实现方面与数据库逻辑交互过于频繁。走了很多的弯路

2.功能实现

1.修改功能(密码、昵称、个性签名)

2.添加好友、删除好友

3.单聊功能

4.判断好友是否在线

3.模块划分

4.使用的知识

netty

swing

集合等同步阻塞队列synchronousQueue

数据库MySQL中的CRUD

C3p0连接池

JSON字符串

5.部分代码实现

1.nettyController.java

接收到来自客户端的消息,与dao层进行交互

dao层与之数据库进行交互

修改密码

添加好友

从添加好友逻辑实现上我走了很多的弯路频繁的访问数据库,这是一件很不好的事情

2.ClientHandler.java

客户端接受来自服务端返回的消息

根据返回的状态码来判断是否操作成功

    @Override
    protected void channelRead0(ChannelHandlerContext channelHandlerContext, String s) throws Exception {

    }

    //客户端接收数据

    public void channelRead(ChannelHandlerContext ctx, Object msg) throws Exception {
        System.out.println(msg);
        //解析服务端发送的消息
        ObjectNode jsonNodes = JsonUtils.getObjectNode((String) msg);

                //登录操作
                queue.offer(jsonNodes.get("code").asInt());
            }else if(EnMsgType.EN_MSG_GETINFORMATION.toString().equals(srctype)){

                 Nickname = jsonNodes.get("Nickname").asText();
                 Signature = jsonNodes.get("Signature").asText();
                linkmen.label_1.setText(Nickname);
                linkmen.field.setText(Signature);
            }else if (EnMsgType.EN_MSG_CHAT.toString().equals(srctype)){
                //发送端返回消息

                int count = jsonNodes.get("count").asInt();
                login.friend = new String[count];
                for ( int i = 0;i
