我使用Tibjms jar 进行 JMS 连接，在正常情况下工作正常，但如果与 jms 提供程序的连接丢失然后又恢复，我就会遇到问题。为了重现该问题，我执行了以下步骤 -
连接内网并启动服务器。工作正常。
断开与内联网的连接。它开始尝试重新连接服务器。美好的。
再次连接内网。它抛出未知异常并且再也不会连接。问题。
所以，我的问题是“javax.jms.JMSException：服务器未知的连接”，它并没有告诉我太多信息，您可以在日志末尾看到它。
您可以从以下日志中看到它 -

我的代码 -
@PostConstruct
public void configurePaxJmsClient() {
try {
// create Topic Connection Factory
TibjmsTopicConnectionFactory cf = new TibjmsTopicConnectionFactory(serverUrl);
cf.setSSLTrustedCertificate(sslCertificatePath);
cf.setSSLEnableVerifyHostName(false);
cf.setUserName(username);
cf.setUserPassword(password);
cf.setReconnAttemptCount(100);
cf.setReconnAttemptDelay(60000);
cf.setReconnAttemptTimeout(10000);
cf.setConnAttemptCount(100);
cf.setConnAttemptDelay(60000);
cf.setConnAttemptTimeout(10000);
Tibjms.setExceptionOnFTEvents(true);
Tibjms.setExceptionOnFTSwitch(true);
// creation the connection and install an exception handler
connection = cf.createTopicConnection(username, password);
connection.setExceptionListener(this);
// You might also use CLIENT_ACKNOWLEDGE here
session = connection.createTopicSession(false, javax.jms.Session.AUTO_ACKNOWLEDGE);
Topic topic = session.createTopic(topicName);
// Create the subscriber and install the listener
TopicSubscriber ts;
/*if (dsName == null || dsName.length() == 0) {
ts = session.createSubscriber(topic);
} else {
ts = session.createDurableSubscriber(topic, dsName);
}*/
if (dsName == null || dsName.length() == 0) {
ts = session.createSubscriber(topic, messageSelector, false);
} else {
ts = session.createDurableSubscriber(topic, dsName, messageSelector, false);
}
//
ts.setMessageListener(this);
connection.start();
} catch (JMSException e) {
LOGGER.error("Failed to connect with message:" + e.getMessage(), e);
releaseResources();
}
}
@Override
public void onException(JMSException e) {
LOGGER.error("Exception received from jms", e);
}
你们能告诉我这里有什么问题或者指出我正确的方向吗？
另外，在 spring bean 的 @PostConstruct 中进行 jms 连接初始化可以吗？

为什么 EMS 会报告 \xe2\x80\x9creconnect failed: connectionunknown for id=xxxxx\xe2\x80\x9d?\n此消息表明当客户端尝试重新连接时，EMS 服务器没有或不再有客户端连接信息。
\n\n可能的原因有两个：
\n\n参数 \xe2\x80\x9cft_reconnect_timeout\xe2\x80\x9d 不够高。在客户端重新连接服务器之前，连接已被服务器清除。\n可以通过在 tibemsd.conf 中为 \xe2\x80\x9cft_reconnect_timeout\xe2\x80\x9d 参数设置更高的值来解决此问题。默认值为 60 秒。
参数 \xe2\x80\x9cft_reconnect_timeout\xe2\x80\x9d 是备份服务器等待客户端重新连接的时间（以秒为单位）\n（在故障转移情况下承担主服务器角色之后），此参数指定服务器将保持挂起连接的时间（以秒为单位）。\n如果客户端在此时间段内未重新连接，服务器将从共享状态文件中删除其状态。\n如果客户端在\xe2\x80\x9cft_reconnect_timeout\xe2\x80\x9d中设置的时间之后尝试重新连接，则服务器没有客户端连接信息并打印“重新连接失败：连接未知”消息。
所以会建议你根据你的环境设置该值并进行测试。另外\n如果Ft_reconnect_timeout值很高，大量连接和连接相关对象在内存中保留很长时间，你可能会遇到内存问题。如果连接使用clientID，您可能会遇到\xe2\x80\x9cclientID已经存在\xe2\x80\x9d问题。
