# netty中channel状态变化过程
## demo描述
- 先启动Server- `com.tony.netty.server.ServerMain`
- 再启动Client- `com.tony.netty.client.ClientMain`
- 最后关闭Client

根据时间状态可以发现channel的变化过程

- 正常连接

server-boss-channelRegistered(isRegistered=true,isOpen=true,isActive=false,isWritable=true) ->
server-boss-channelActive(isRegistered=true,isOpen=true,isActive=true,isWritable=true) ->
client-channelRegistered(isRegistered=true,isOpen=true,isActive=false,isWritable=true) ->
client-channelActive(isRegistered=true,isOpen=true,isActive=true,isWritable=true) ->
server-boss-channelRead(isRegistered=true,isOpen=true,isActive=true,isWritable=true) ->
server-child-channelRegistered(isRegistered=true,isOpen=true,isActive=true,isWritable=true) ->
server-child-channelActive(isRegistered=true,isOpen=true,isActive=true,isWritable=true)

- 断开客户端

server-child-exceptionCaught(isRegistered=true,isOpen=true,isActive=true,isWritable=true) ->
server-child-channelInactive(isRegistered=true,isOpen=false,isActive=false,isWritable=false) ->
server-child-channelUnregistered(isRegistered=false,isOpen=false,isActive=false,isWritable=false)
出现异常:java.io.IOException: 远程主机强迫关闭了一个现有的连接。

- 重启客户端

server-boss-channelRead(isRegistered=true,isOpen=true,isActive=true,isWritable=true) ->
server-child-channelRegistered(isRegistered=true,isOpen=true,isActive=true,isWritable=true) ->
server-child-channelActive(isRegistered=true,isOpen=true,isActive=true,isWritable=true)
