I am using the Channle pool API code written here:
ChannelPool
section http://netty.io/news/2015/05/07/4-0-28-Final.html
EventLoopGroup group = new NioEventLoopGroup();
final Bootstrap cb = new Bootstrap();
InetSocketAddress addr1 = new InetSocketAddress("10.0.0.10", 8888);
InetSocketAddress addr2 = new InetSocketAddress("10.0.0.11", 8888);
cb.group(group).channel(NioSocketChannel.class);
ChannelPoolMap<InetSocketAddress, SimpleChannelPool> poolMap = new AbstractChannelPoolMap<InetSocketAddress, SimpleChannelPool>() {
@Override
protected SimpleChannelPool newPool(InetSocketAddress key) {
return new SimpleChannelPool(cb.remoteAddress(key), new TestChannelPoolHandler());
}
};
// depending on when you use addr1 or addr2 you will get different pools.
final SimpleChannelPool pool = poolMap.get(addr1);
Future<Channel> f = pool.acquire();
f.addListener(new FutureListener<Channel>() {
@Override
public void operationComplete(Future<Channel> f) {
if (f.isSuccess()) {
Channel ch = f.getNow();
// Do somethings
// ...
// ...
// Release back to pool
pool.release(ch);
}
}
});
As i see the code we never called .connect
method so my question is when netty trying to connecting my channel to server ?
As you use SimpleChannelPool it will do connect when you call acquire and there is nothing left in the ChannelPool.
