public class Test {
public static void main(String[] args) throws IOException, MqttException {
MqttConnectOptions mqttConnectOptions = new MqttConnectOptions();
mqttConnectOptions.setUserName("test");
mqttConnectOptions.setPassword("test".toCharArray());
mqttConnectOptions.setCleanSession(true);
mqttConnectOptions.setKeepAliveInterval(30);
mqttConnectOptions.setConnectionTimeout(2);
MqttAsyncClient mq = new MqttAsyncClient("tcp://127.0.0.1:61611","test", new MemoryPersistence());
try {
IMqttToken token = mq.connect(mqttConnectOptions);
Thread.sleep(5000);
System.out.println(token.isComplete());
} catch (Exception e) {
e.printStackTrace();
}
}
}
The above example is a code that makes a connect request to any server without a message broker.
If you follow the code inside the library(package org.eclipse.paho.client.mqttv3.internal.TCPNetworkModule(line:67 start())
public void start() throws IOException, MqttException {
final String methodName = "start";
try {
// @TRACE 252=connect to host {0} port {1} timeout {2}
log.fine(CLASS_NAME,methodName, "252", new Object[] {host, Integer.valueOf(port), Long.valueOf(conTimeout*1000)});
SocketAddress sockaddr = new InetSocketAddress(host, port);
socket = factory.createSocket();
socket.connect(sockaddr, conTimeout*1000);
socket.setSoTimeout(1000);
}
catch (ConnectException ex) {
//@TRACE 250=Failed to create TCP socket
log.fine(CLASS_NAME,methodName,"250",null,ex);
throw new MqttException(MqttException.REASON_CODE_SERVER_CONNECT_ERROR, ex);
}
}
you will call Socket connect.
Socket connect() for non-operating servers will cause ConnectException.
On the code, the generated ConnectException is thrown as MqttException.
But I can't get any reception, the project I made doesn't work normally.
Am I misunderstanding and using it?
