<div style="color: black; text-align: left; margin-bottom: 10px;">
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">J-IM 是用JAVA语言,基于t-io<span style="color: black;">研发</span>的轻量、高性能、单机支持几十万至百万在线用户IM，<span style="color: black;">重点</span><span style="color: black;">目的</span>降低即时通讯门槛，快速打造低成本接入在线IM系统，<span style="color: black;">经过</span>极简洁的<span style="color: black;">信息</span>格式就<span style="color: black;">能够</span>实现多端<span style="color: black;">区别</span>协议间的<span style="color: black;">信息</span>发送如内置(Http、Websocket、Tcp自定义IM协议)等，并<span style="color: black;">供给</span><span style="color: black;">经过</span>http协议的api接口进行<span style="color: black;">信息</span>发送无需关心接收端属于什么协议，一个<span style="color: black;">信息</span>格式搞定一切！</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">重点</span>特点</p>1、高性能(单机可支持几十万至百万人<span style="color: black;">同期</span>在线)
2、轻量、可扩展性极强
3、支持集群多机<span style="color: black;">安排</span>
4、支持SSL/TLS加密传输
5、<span style="color: black;">信息</span>格式极其简洁(JSON)
6、支持多种协议(Socket自定义IM协议、Websocket、Http),可分别独立<span style="color: black;">安排</span>。
7、内置<span style="color: black;">信息</span>持久化(离线、历史、漫游)，<span style="color: black;">保准</span><span style="color: black;">信息</span><span style="color: black;">靠谱</span>性，高性能存储
8、<span style="color: black;">各样</span>丰富的API接口。
9、零成本<span style="color: black;">安排</span>，一键<span style="color: black;">起步</span>。<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">信息</span>格式</p>
