與用戶名連接時出現paho java客戶端的問題&密碼？Paho java客戶端連接失敗：用戶名或密碼不正確（4）
從paho JS客戶端它工作，但從Java客戶端它沒有。 我有這樣的代碼
MqttConnectOptions conOpt = new MqttConnectOptions();
conOpt.setCleanSession(false);
conOpt.setUserName("test5");
conOpt.setPassword("123".toCharArray());
MqttDefaultFilePersistence filePersistence = new MqttDefaultFilePersistence("/home/manish/Downloads/mqttPersist");
client = new MqttAsyncClient(appProps.getProperty("mqtt.broker"),
appProps.getProperty("mqtt.clientId"), filePersistence);
client.setCallback(this);
client.connect(conOpt, new IMqttActionListener() {
@Override
public void onSuccess(IMqttToken imt) {
try {
client.subscribe(Constants.INTERNAL_TOPICS, Constants.INTERNAL_TOPIC_QOS);
} catch (MqttException ex) {
ex.printStackTrace();
}
}
@Override
public void onFailure(IMqttToken imt, Throwable thrwbl) {
thrwbl.printStackTrace();
}
});
我得到這個例外
Bad user name or password (4)

據泛美衛生組織文檔公共無效setPassword（的char []密碼），所以我在這裏路過的char []作爲paasword
我正在使用emqttd經紀商
