Я написал код клиента netty для отправки некоторых обработанных данных нескольким клиентам.После 3-4 часов работы я исчерпал все розетки и больше никаких подключений невозможно.Также, когда я проверяю состояния сокетов в ОС, большое количество сокетов находится в состоянии TIME_WAIT.
public class NettyClient {
private static LogHelper logger = new LogHelper(NettyClient.class);
private static EventLoopGroup workerGroup = new NioEventLoopGroup();
private static Bootstrap nettyClient = new Bootstrap()
.group(workerGroup)
.channel(NioSocketChannel.class)
.option(ChannelOption.SO_KEEPALIVE, true)
.option(ChannelOption.CONNECT_TIMEOUT_MILLIS, 5000);
private URL url;
private RequestVo Req;
private ChannelFuture chFuture;
private Object ReportData;
private JAXBContext jbContext;
private static final int CHANNEL_READ_TIMEOUT = 5;
public NettyClient() {
// TODO Auto-generated constructor stub
}
public NettyClient(RequestVo Req, JAXBContext jbCtx,Object data) {
this.Req = Req;
this.ReportData = data;
this.jbContext = jbCtx;
}
public void sendRequest() {
logger.debug("In sendRequest()");
//ChannelFuture chFuture = null;
try {
this.url = new URL(Req.getPushAddress());
//add handlers
nettyClient.handler(new ChannelInitializer<SocketChannel>() {
@Override
public void initChannel(SocketChannel ch) {
ch.pipeline()
.addLast("timeout",
new ReadTimeoutHandler(CHANNEL_READ_TIMEOUT, TimeUnit.SECONDS));
ch.pipeline()
.addLast("codec", new HttpClientCodec());
ch.pipeline()
.addLast("inbound",
new NettyClientInBoundHandler(Req, jbContext, ReportData));
}
});
//make a connection to the Client
int port = url.getPort() == -1? url.getDefaultPort():url.getPort();
chFuture = nettyClient.connect(url.getHost(), port);
chFuture.addListener(new NettyClientConnectionListener(this.Req.getRequestId()));
} catch (Exception e) {
logger.error("Exception: Failed to connect to Client ", e);
} finally {
}
}
}
Вот методы из класса ChannelInBoundHandler
@Override
public void channelRead(ChannelHandlerContext ctx, Object msg) throws Exception
{
Map<String, String> props = new HashMap<String, String>();
if(msg instanceof HttpResponse) {
logger.debug("channelRead()");
HttpResponse httpRes = (HttpResponse) msg;
HttpResponseStatus httpStatus = httpRes.status();
props.put(REQUEST_ID, this.Request.getRequestId());
props.put(CLIENT_RESPONSE_CODE, String.valueOf(httpStatus.code()));
JmsService.getInstance(DESTINATION).sendTextMessage(props, "");
logger.debug("channelRead() HttpResponse Code: " + httpStatus.code());
ctx.close();
}
}
@Override
public void exceptionCaught(ChannelHandlerContext ctx, Throwable cause) throws Exception
{
Map<String, String> props = new HashMap<String, String>();
logger.error("exceptionCaught()", cause);
if(cause instanceof ReadTimeoutException) {
//If read-timeout, send back the response
props.put(REQUEST_ID, this.Request.getRequestId());
props.put(CLIENT_RESPONSE_CODE,
String.valueOf(HttpResponseStatus.REQUEST_TIMEOUT.code()));
JmsService.getInstance(DESTINATION).sendTextMessage(props, "");
ctx.close();
}
else {
logger.error("Exception: ", cause);
}
}
Любая идея, что не такв коде очень помог бы мне.Спасибо
