Class ServerInitializer

java.lang.Object

io.netty.channel.ChannelHandlerAdapter

io.netty.channel.ChannelInboundHandlerAdapter

io.netty.channel.ChannelInitializer<io.netty.channel.socket.SocketChannel>

server.netty.ServerInitializer

All Implemented Interfaces:

io.netty.channel.ChannelHandler, io.netty.channel.ChannelInboundHandler

public class ServerInitializer
extends io.netty.channel.ChannelInitializer<io.netty.channel.socket.SocketChannel>

Netty ChannelInitializer，為每個新的 TCP 連線組裝封包處理 pipeline。

當客戶端完成 TCP 握手後，initChannel(SocketChannel) 依序向 pipeline 加入：

• IdleStateHandler（25 秒讀寫逾時，偵測殭屍連線）。
• MaplePacketDecoder（入站：解密並還原封包位元組陣列）。
• MaplePacketEncoder（出站：加密並寫入網路緩衝區）。
• MapleServerHandler（業務邏輯：opcode 分派、MapleClient 管理）。

由 ServerConnection 在 ServerBootstrap.childHandler 中使用； ServerType 與頻道資訊在建構時注入，並透傳給 MapleServerHandler 以區分登入／頻道／商城伺服器的處理邏輯。
