我已经使用smack api创建了一个xmpp客户端。并且为了创建名单条目，我使用了以下代码。
public void likeOnXmpp(UserFriendsBaseModel userFriendsBaseModel) {
AbstractXMPPConnection con = null;
try {
con = new SecuredXmppConnectionImpl(SecuredXmppConnectionImpl.getConfig(xmppResource.getXmppHost(), Integer.parseInt(xmppResource.getXmppSSLPort()))).connect();
if (con != null) {
xmppLogin(con, String.valueOf(userFriendsBaseModel.getUserId()), generatePassword(userFriendsBaseModel.getUserId()));
addFriendInXMPP(String.valueOf(userFriendsBaseModel.getUserId()),
generatePassword(userFriendsBaseModel.getUserId()),
String.valueOf(userFriendsBaseModel.getFriendId()),
String.valueOf(generatePassword(userFriendsBaseModel
.getFriendId())),
getProfileName(userFriendsBaseModel.getFriendId()), con);
removeRosterFailureRequest(userFriendsBaseModel);
} else {
addRosterFailureRequest(userFriendsBaseModel);
logger.info("LIKE saved in Roster Failure : "+userFriendsBaseModel.getUserId()+" -> "+userFriendsBaseModel.getFriendId());
}
} catch (XMPPException | SmackException | IOException
| InternalServerError e1) {
logger.error("unable to login at xmpp ", e1);
addRosterFailureRequest(userFriendsBaseModel);
logger.info("LIKE saved in Roster Failure : "+userFriendsBaseModel.getUserId()+" -> "+userFriendsBaseModel.getFriendId());
}
将Roster方法代码添加为：
private void addFriendInXMPP(String username, String password, String contactUserName, String contactPassword, String name,
AbstractXMPPConnection userConnection) throws InternalServerError {
try {
userConnection.setPacketReplyTimeout(20000);
xmppRosterManager.createEntry(userConnection, getBareJID(contactUserName), name, new String[] { "Friends" });
} catch (XMPPException e) {
logger.error("unable to create roster entry : ", e);
throw new InternalServerError();
} catch (SmackException e) {
logger.error("unable to create roster entry : ", e);
throw new InternalServerError();
}
}
和createEntry：
@Override
public void createEntry(AbstractXMPPConnection connection, String jId, String name, String[] groups)
throws XMPPException, NotLoggedInException, NoResponseException, NotConnectedException {
//getting instance of a roster
Roster.setDefaultSubscriptionMode(SubscriptionMode.manual);
Roster.getInstanceFor(connection).createEntry(jId, name, groups); // adding a entry in roster
}
这是SecuredXmppConnectionImpl类的代码
public class SecuredXmppConnectionImpl extends XmppConnectionImpl {
public SecuredXmppConnectionImpl(XMPPTCPConnectionConfiguration config) {
super(config);
}
/**
* Returns default configuration for Old SSL port method
*
* @param serviceName
* @param port
* @return
* @throws GeneralSecurityException
* @throws NoSuchAlgorithmException
* @throws KeyManagementException
*/
public static XMPPTCPConnectionConfiguration getConfig(String serviceName,
int port) throws KeyManagementException, NoSuchAlgorithmException {
SSLContext sslcontext = SSLContext.getInstance("TLS");
sslcontext.init(
null, // KeyManager not required
new TrustManager[] { new DummyTrustManager() },
new java.security.SecureRandom());
SSLSocketFactory ssf = sslcontext.getSocketFactory();
return XMPPTCPConnectionConfiguration.builder()
.setServiceName(serviceName).setHost(serviceName).setPort(port)
.setSocketFactory(ssf).build();
}
static class DummyTrustManager implements X509TrustManager {
public boolean isClientTrusted(X509Certificate[] cert) {
return true;
}
public boolean isServerTrusted(X509Certificate[] cert) {
try {
cert[0].checkValidity();
return true;
} catch (CertificateExpiredException e) {
return false;
} catch (CertificateNotYetValidException e) {
return false;
}
}
public void checkClientTrusted(X509Certificate[] x509Certificates,
String s) throws CertificateException {
// Do nothing for now.
}
public void checkServerTrusted(X509Certificate[] x509Certificates,
String s) throws CertificateException {
// Do nothing for now.
}
public X509Certificate[] getAcceptedIssuers() {
return new X509Certificate[0];
}
}
}
但有时我得错误为：
key =javax.crypto.spec.SecretKeySpec@15f8b

我无法识别问题，我该如何解决？或者我需要做什么才能在给定时间内收听回复节？
