five111 opened a new issue #2654:
URL: https://github.com/apache/servicecomb-java-chassis/issues/2654
### 背景如下
应用在现网跑了一段时间 偶现
io.netty.channel.connecttimeoutexception connection timed out
应该是tcp连接超时了 具体发送请求仅过去了1s 查看netty源码如下
```
@Override
public final void connect(
final SocketAddress remoteAddress, final SocketAddress
localAddress, final ChannelPromise promise) {
if (!promise.setUncancellable() || !ensureOpen(promise)) {
return;
}
try {
if (connectPromise != null) {
// Already a connect in process.
throw new ConnectionPendingException();
}
boolean wasActive = isActive();
if (doConnect(remoteAddress, localAddress)) {
fulfillConnectPromise(promise, wasActive);
} else {
connectPromise = promise;
requestedRemoteAddress = remoteAddress;
// Schedule connect timeout.
int connectTimeoutMillis =
config().getConnectTimeoutMillis();
if (connectTimeoutMillis > 0) {
connectTimeoutFuture = eventLoop().schedule(new
Runnable() {
@Override
public void run() {
ChannelPromise connectPromise =
AbstractNioChannel.this.connectPromise;
if (connectPromise != null &&
!connectPromise.isDone()
&& connectPromise.tryFailure(new
ConnectTimeoutException(
"connection timed out: " +
remoteAddress))) {
close(voidPromise());
}
}
}, connectTimeoutMillis, TimeUnit.MILLISECONDS);
}
promise.addListener(new ChannelFutureListener() {
@Override
public void operationComplete(ChannelFuture future)
throws Exception {
if (future.isCancelled()) {
if (connectTimeoutFuture != null) {
connectTimeoutFuture.cancel(false);
}
connectPromise = null;
close(voidPromise());
}
}
});
}
} catch (Throwable t) {
promise.tryFailure(annotateConnectException(t,
remoteAddress));
closeIfClosed();
}
}
```
netty 的默认配置应该是 30s
```
int connectTimeoutMillis = config().getConnectTimeoutMillis();
@Override
public int getConnectTimeoutMillis() {
return connectTimeoutMillis;
}
private volatile int connectTimeoutMillis = DEFAULT_CONNECT_TIMEOUT;
private static final int DEFAULT_CONNECT_TIMEOUT = 30000;
```
请问是否是java-chassis做了一层配置 ，如果是 该如何修改这个超时时间
