校园宿舍管理系统的设计与实现

需求

实现即时网络通讯系统功能，主要功能需求如下：
（1）登录功能：客户端在登录时，需要向服务器发送请求，验证请求账号是否和服务端数据库已存数据匹配，只有在匹配状态下，才能登录。
（2）注册功能：客户端实现注册功能，注册成功的账号需要导入到服务端数据库中。
（3）添加好友：客户端通过指定好友方唯一标识添加对方，当添加成功后，对方好友要能显示出添加好友方的相关信息。
（4）删除好友：客户端将指定好友删除后，本好友列表中对应好友将不再显示，对方好友列表中也不再显示删除方。
（5）文件传输：文件的传输需要被传输方的同意请求后方可发送，传输的类型包括音频文件、视频文件、文本文件等所有类型的文件。
（6）好友资料：每个用户都有自己的对应资料，每个用户都能查看自己好友的相关资料。
（7）文字聊天：用户在指定与某位好友聊天时，能够发送任意文字，对方的消息框中也能展现出同样的数据，并能显示出时间戳。另外，用户可以自定义自己的聊天消息框的文本属性。
（8）信息修改：个人信息要求要从服务端数据库提取和操作，可以实现基本信息的录入和修改，也可以实现相关密码的修改。
