У меня проблема с моим приложением SpringBoot Camel.
Он очень хорошо работает с не встроенным брокером. Вот его конфигурация: URL-адрес задается в виде строки, указывающей либо на автономный сервер ActiveMQ, либо на встроенный URL-адрес брокера (vm://dpcgbroker?broker.persistent=false)
@Configuration
public class CamelConfiguration {
@Value("${broker.mqURL}")
String mqURL;
@Bean
CamelContextConfiguration contextConfiguration() {
return new CamelContextConfiguration() {
@Override
public void beforeApplicationStart(CamelContext context) {
ActiveMQComponent activeMQComponent = ActiveMQComponent.activeMQComponent(mqURL);
activeMQComponent.setConfiguration(getJmsConfiguration());
context.addComponent("jms", activeMQComponent);
DefaultShutdownStrategy shutdownStrategy = new DefaultShutdownStrategy();
shutdownStrategy.setTimeUnit(TimeUnit.SECONDS);
shutdownStrategy.setTimeout(20);
context.setShutdownStrategy(shutdownStrategy);
}
@Override
public void afterApplicationStart(CamelContext camelContext) {
}
};
}
public PooledConnectionFactory getPooledConnectionFactory() {
PooledConnectionFactory pooledConnectionFactory = new PooledConnectionFactory(getConnectionFactory());
pooledConnectionFactory.setMaxConnections(30);
return pooledConnectionFactory;
}
public ActiveMQConnectionFactory getConnectionFactory() {
ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory();
connectionFactory.setBrokerURL(mqURL);
connectionFactory.setTrustAllPackages(true);
return connectionFactory;
}
public JmsConfiguration getJmsConfiguration() {
JmsConfiguration jmsConfiguration = new JmsConfiguration();
jmsConfiguration.setDisableTimeToLive(true);
jmsConfiguration.setTransacted(true);
jmsConfiguration.setLazyCreateTransactionManager(false);
jmsConfiguration.setConnectionFactory(getConnectionFactory());
jmsConfiguration.setCacheLevelName("CACHE_CONSUMER");
return jmsConfiguration;
}
@Bean
@Scope(value = ConfigurableBeanFactory.SCOPE_SINGLETON)
public PlatformTransactionManager getTransactionManager() {
PlatformTransactionManager platformTransactionManager = new JmsTransactionManager(getConnectionFactory());
return platformTransactionManager;
}
Когда я переключаюсь на встроенный брокер, поведение меняется, и Apache ActiveMQ запускается, затем останавливается, а затем перезапускается. Я понятия не имею, почему, и нет никаких исключений
Вот выдержка из логов

Проблема в том, что некоторые сообщения отправляются в первом экземпляре брокера, которые теряются при его остановке, тогда второй экземпляр начинается с пустого списка сообщений. Я понятия не имею, почему он останавливается.
PS: я не хочу использовать постоянный встроенный брокер, это бесполезный обходной путь.
