ICQ
我一直都想编一个自己的聊天软件，像QQ那种；最近有时间我就自己编了一个。编写的过程中收获很大……
现在拿出来跟大家分享，有兴趣的朋友可以和我交流交流。
先给大家看一下效果：
启动服务器：
再给大家看一下简陋的登录窗口/(ㄒoㄒ)/~~输入密码登录：
终于进入主题了O(∩_∩)O！客户端主界面：
Mary给Yuan发一个消息：
Yuan打开消息框进行回复：
我们再来看一下群发功能，群发首先得多叫几个好友上线，要不谁知道他们有没有收到……
188的好友们先把队形站好，接下来就等着188给你们发消息吧
这时候老大就要登场准备讲话了：
假设Marry有一天新认识一个好基友，那怎么添加好友呢？接下给给大家看一看添加好友功能：
那个陌生的好基友从哪来呢？不如现造一个（注册用户）：
登录小花，Mary再添加小花为好友：
点击添加好友按钮，输入对方账号：
基友花花收到好友请求后，好友请求按钮就会被点亮，如果没有好友请求的话，这个按钮是失效的。
花花现在需要做的就是同意添加好友，当然，花花也有权拒绝，但是突然有妹子加好友，花花怎么会拒绝呢，\(^o^)/~。
同意，Marry和花花就能开心地聊天了。
还有离线消息没给大家贴图：相比大家也看腻了吧，贴了这么多图，唯一的感触就是window的蓝色主题背景还真的挺好看的。O(∩_∩)O哈！
技术细节：
我编写的这个软件分三步分组成:数据库部分、服务器部分、客户端部分。实现的过程中采用MVC模式。
整个系统中的核心部分在于服务器端接收用户请求、解析请求、处理请求；客户端接收服务器消息、解析消息、处理并显示消息。
下面定义了本系统客户端与服务器端通信的请求码：
客户端请求码与服务器返回结果:
00:登录 例如：00:123,123 表示用户账号123，密码123请求登录；登录成功服务器会给客户端发送：
>>>00:123,123
>>>001:123,Tom;120,Yuan;124,John;&$119,123;&$120,123,2016-9-11 15:24:11,你好;120,123,2016-9-11 15:25:11,你好;120,123,2016-9-11 15:26:11,你好;
返回的信息被&$分成三段，第一段表示用户本身与好友列表，第二字段表示收到119申请添加好友的请求，第三段表示离线消息。每段内的记录以‘;’分隔;每条记录里的参数以‘,’分隔；
10:查询与指定好友的历史消息 10：120,119 表示查询120与119的聊天记录；返回示例：
>>>10,120,119
>>>101:120,119,2016-1-12 0:00:00,hello;120,119,2016-8-10 0:00:00,你好;120,119,2016-8-10 0:00:00,你好,我是120;120,119,2016-8-10
0:00:00,nihao;120,119,2016-8-10 0:00:00,nihao;120,119,2016-8-10 0:00:00,nihao;120,119,2016-8-10 0:00:00,213213;119,120,
2016-8-10 0:00:00,你好;119,120,2016-8-10 0:00:00,hello;119,120,2016-8-10 0:00:00,Hi;119,120,2016-8-10 0:00:00,hello
;119,120,2016-8-10 0:00:00,hi;119,120,2016-8-10 0:00:00,哈哈; 每条历史消息以‘;’为间隔。
11:点对点发msg 11:120,119,2016-7-16 10:10:10，hello 表示120给119发送点对点消息“hello”,时间为2016-7-16 10:10:10
12:群发好友msg 12:120,120,2016-7-16 11:11:11，大家好，我是120 表示120给所有好友群发消息，与点对点发消息有所不同的是这里的接收方发送方都是自己账号；
13:删除历史消息 13:120,119 表示120请求删除与119的聊天记录；这里需要注意的一点是，用户删除聊天记录是仅仅是把数据库中消息表中的d字段置0了，用户查询历史聊天记录时也会检查d字段，对于那些d字段为0的消息是检索不到的，就好像自己把它已经删除了一样；
20:获得好友列表 20:120 表示请求120的好友列表
>>>20:120
>>>201:122,Yaze;123,Tom;130,M;
21:添加好友 21:120,130 表示120请求添加130为好友，服务器端就会根据可以请求在数据库表failrelation（未确认好友关系表）中创建一条记录；
22:删除好友 22:120,119 表示120删除好友119，服务器端根据请求会在relation表中删除相应记录，并对在用用户进行通知；
23:确认添加好友 23：130,120 表示130同意添加120为好友，服务器端会删除相应的failrelation记录，并在relation中添加一个记录（添加时调整id顺序，使其检索方便，这里是使数值小的id放在前面）；
24:拒绝添加好友
30:更改用户名 30：120，Yozane,120 表示把账号120的用户名更改为Yozane，返回修改后的用户信息
>>>30:152,jiaGu,170
>>>301:152,jiaGu,170
31:更改用户密码 30:120，新密码，旧密码
>>>31:152,152,170
>>>301:152,jiaGu,152
40:注册新用户 40:Tommy,130 表示申请注册用户名为Tommy,密码为130的用户。
示例：
>>>40:Jia,170
>>>401:152,Jia,170
