netty 异常处理

相关类与接口

ChannelInboundHandler

public interface ChannelInboundHandler extends ChannelHandler {

    void channelRegistered(ChannelHandlerContext var1) throws Exception;
    void channelUnregistered(ChannelHandlerContext var1) throws Exception;

    void channelActive(ChannelHandlerContext var1) throws Exception;
    void channelInactive(ChannelHandlerContext var1) throws Exception;

    void channelRead(ChannelHandlerContext var1, Object var2) throws Exception;
    void channelReadComplete(ChannelHandlerContext var1) throws Exception;

    void userEventTriggered(ChannelHandlerContext var1, Object var2) throws Exception;
    void channelWritabilityChanged(ChannelHandlerContext var1) throws Exception;

    void exceptionCaught(ChannelHandlerContext var1, Throwable var2) throws Exception;
}        //处理inbound事件异常

ChannelOutboundHandler

public interface ChannelOutboundHandler extends ChannelHandler {

    void bind(ChannelHandlerContext var1, SocketAddress var2, ChannelPromise var3) throws Exception;
    void connect(ChannelHandlerContext var1, SocketAddress var2, SocketAddress var3, ChannelPromise var4) throws Exception;
    void disconnect(ChannelHandlerContext var1, ChannelPromise var2) throws Exception;

    void close(ChannelHandlerContext var1, ChannelPromise var2) throws Exception;
    void deregister(ChannelHandlerContext var1, ChannelPromise var2) throws Exception;

    void read(ChannelHandlerContext var1) throws Exception;
    void write(ChannelHandlerContext var1, Object var2, ChannelPromise var3) throws Exception;
         //可处理write事件抛出的异常

    void flush(ChannelHandlerContext var1) throws Exception;
}

ChannelDuplexHandler：可同时处理inbound、outb
