# ChatSystem 基于python的在线聊天系统 1.本程序客户端启动必须先配置好数据库再开启服务器 2.服务器的启动方法：Server中的server代码 3.客户端的启动方式，运行Client目录下的main 4.数据库的更改在server的dao中 -----------以下数据库创建程序---------- create database chatsystem; create table chatsystem.user ( U_ID int auto_increment, U_LoginID varchar(25) null, U_NickName varchar(25) null, U_PassWord varchar(25) null, U_Name varchar(25) null, U_Sex bit null, U_Age int null, constraint user_pk primary key (U_ID) ); create table chatsystem.friends ( F_ID int auto_increment primary key, F_FirendID int null, F_UserID int null, constraint Friends_user_U_ID_fk foreign key (F_UserID) references user (U_ID), constraint Friends_user_U_ID_fk_2 foreign key (F_FirendID) references user (U_ID) ); create table chatsystem.Messages ( M_ID int auto_increment, M_FromUserID int null, M_ToUserID int null, M_PostMessages text null, M_Time datetime null, constraint Messages_pk primary key (M_ID), constraint Messages_user_U_ID_fk foreign key (M_FromUserID) references user (U_ID), constraint Messages_user_U_ID_fk_2 foreign key (M_ToUserID) references user (U_ID) );
