 #服务端集群配置方案
 ###服务端修改
-1.多台服务器集群配置，首先需要重写SessionManager接口，用户登录时，将账号和服务器IP 存入数据库中，这样就可以统计各台服务器接受的连接数量。
+1.多台服务器集群配置，首先需要重写SessionManager接口(参考com.farsunset.ichat.cim.session.ClusterSessionManager.java)，用户登录时，将账号和服务器IP 存入数据库中，这样就可以统计各台服务器接受的连接数量。
 2.客户端连接服务器时，服务端为客户端动态分配 服务器IP，每次分配 较为空闲的服务器IP
 3.服务端接受消息后 通过接收者账号查询出对应的Iosession，和 登录的 服务器IP，然后将消息信息传往目标服务器处理发送
