正在做一个java web项目，需要与netty服务端通信，就写了一个netty客户端，客户端单独运行
时可以通信，也就是放在main函数里面可以运行，嵌入项目时就报错，不知道是什么原因，求指教！以下是项目中启动客户端代码，netty客户端代码以及报错信息。
启动代码：
NettyClient nc = new NettyClient();
nc.connect();
netty客户端代码：
public class NettyClient {
public void connect() throws Exception {
EventLoopGroup group = new NioEventLoopGroup();
try {
Bootstrap b = new Bootstrap();
b.group(group).channel(NioSocketChannel.class)
.option(ChannelOption.TCP_NODELAY, true)
.handler(new ChannelInitializer() {
public void initChannel(SocketChannel ch)
throws Exception {
ch.pipeline().addLast(new MyClientHandler());
}
});
int port=8097;
String host="192.168.41.141";
ChannelFuture f = b.connect(host, port).sync();
f.channel().closeFuture().sync();
} finally {
group.shutdownGracefully();
}
}
}
public class MyClientHandler extends ChannelHandlerAdapter {
@Override
public void channelActive(ChannelHandlerContext ctx) {
byte[] send={1,86,1,1};
ByteBuf Bsend =Unpooled.copiedBuffer(send);
ctx.writeAndFlush(Bsend);
ctx.close();
}
public void channelRead(ChannelHandlerContext ctx, Object msg)
throws Exception {
}
public void exceptionCaught(ChannelHandlerContext ctx, Throwable cause) {
ctx.close();
}
}
报错信息：
