我为一个http客户端使用netty通道池,在ChannelPoolHandler
实现中channelAcquired
在调用channelPool.acquire()
时没有被调用。我正在使用netty 4.0.32.Final
。以下是我创建chanelpool的方式。我只是遵循netty.io中列出的简单示例。如果有人能够解释我做错了什么,或者是否有一个会非常有用的错误。谢谢。Netty channelAcquired没有被调用
EventLoopGroup group = new NioEventLoopGroup();
final Bootstrap b = new Bootstrap();
b.group(group).channel(NioSocketChannel.class);
AbstractChannelPoolMap<InetSocketAddress, SimpleChannelPool> poolMap = new AbstractChannelPoolMap<InetSocketAddress, SimpleChannelPool>() {
@Override
protected SimpleChannelPool newPool(InetSocketAddress key) {
return new SimpleChannelPool(b.remoteAddress(key), new HttpClientPoolHandler());
}
};
final SimpleChannelPool simpleChannelPool = poolMap.get(new InetSocketAddress(uri.getHost(), uri.getPort()));
final Future<Channel> acquire = simpleChannelPool.acquire();
acquire.addListener(new FutureListener<Channel>() {
public void operationComplete(Future<Channel> f) throws Exception {
if (f.isSuccess()) {
final Channel ch = f.getNow();
// Send the HTTP request.
ChannelFuture channelFuture = ch.writeAndFlush(request);
channelFuture.addListener(new ChannelFutureListener() {
public void operationComplete(ChannelFuture channelFuture) throws Exception {
if (channelFuture.isSuccess()) {
simpleChannelPool.release(ch);
} else {
}
}
});
} else {
System.out.println("ERROR : " + f.cause());
}
}
});
看看netty源代码,我发现'channelAcquired'方法只在池中有一个先前释放的通道时被调用。否则创建一个新通道而不调用'channelAcquired'方法。这是它应该的方式吗? – Sudheera
