Java项目:在线聊天及聊天室系统(java+springboot+freemark+websocket+MySQL)

Java项目:在线聊天及聊天室系统(java+springboot+freemark+websocket+MySQL) springboot+freemark+websocket+MySQL实现的Java web在线聊天系统，主要实现的功能有： 前台：

1、用户注册、登录。

2、搜索用户添加好友。

3、查看好友申请列表，同意或拒绝好友请求。

4、成为好友后单人一对一聊天。

5、可创建群聊进行聊天。

除了上述基本的聊天功能外，还有：消息提醒方式设置（可设置是否d框、是否声音提醒等，提供可选六种新消息提示音）、聊天记录清空、拉黑好友、删除好友、解散群聊、隐身、在线状态设置、好友上下线提醒等等，功能非常的全。

重点：聊天信息中可发送文字、图片、文件、视频、音乐、表情包等。

后台：

1、后台菜单、角色、管理员的管理。

2、后台聊天信息、在线用户等统计。

3、后台日志管理、数据备份等。

4、用户管理：用户信息查看、状态冻结等。

5、群聊管理：成员查看、移除成员、解散群聊等。

6、消息管理：消息详细信息跟踪查看等。
