I'm using Spring Boot 1.2.0.RC1 + bitronix + hornetq (embedded) + JPA, and I'd like to increase bitronix jmsConnectionFactory pool size, currently it's limited at 10. Is there a simple way to do it, inside application.properties for example or inside a #Configuration class?
You can't configure it via application.properties at the moment (I've opened an issue), but you can do it from a #Configuration class by declaring your own XAConnectionFactoryWrapper bean:
#Bean
public XAConnectionFactoryWrapper xaConnectionFactoryWrapper() {
return new XAConnectionFactoryWrapper() {
#Override
public ConnectionFactory wrapConnectionFactory(
XAConnectionFactory connectionFactory) {
PoolingConnectionFactoryBean pool = new PoolingConnectionFactoryBean();
pool.setConnectionFactory(connectionFactory);
pool.setMaxPoolSize(50);
return pool;
}
};
}

I am trying to implement Hibernate second level caching in a Spring boot project using Redisson.
I have followed this blog as a reference
https://pavankjadda.medium.com/implement-hibernate-2nd-level-cache-with-redis-spring-boot-and-spring-data-jpa-7cdbf5632883
Also i am trying to initialize the RedissionClient programmatically and not through declaratively /through a config file
Created a spring bean to be initialized which should create the RedissonClient instance.
#Configuration
#Lazy(value = false)
public class RedissonConfig {
#Bean
public RedissonClient redissionClient() {
Config config = new Config();
config.useSingleServer().setAddress("redis://127.0.0.1:6379");
return Redisson.create(config);
}
}
However this bean is never intialized and i get the following error while application startup.
Caused by: org.hibernate.cache.CacheException: Unable to locate Redisson configuration
at org.redisson.hibernate.RedissonRegionFactory.createRedissonClient(RedissonRegionFactory.java:107) ~[redisson-hibernate-53-3.12.1.jar:3.12.1]
at org.redisson.hibernate.RedissonRegionFactory.prepareForUse(RedissonRegionFactory.java:83) ~[redisson-hibernate-53-3.12.1.jar:3.12.1]
It seems Spring boot Hibernate still trying to load the Redisson config through a config file.
is it possible to load the Redission config in spring boot programmatically ?
Best Regards,
Saurav
I just did exactly this, here is how:
you need a custom RegionFactory that is similar to the JndiRedissonRegionFactory but gets its RedissonClient injected somehow.
an instance of this Class, fully configured, is put into the hibernate-properties map. Hibernates internal code is flexible: if the value of hibernate.cache.region.factory_class is a string it is treated as a FQDN. If it is an instance of Class<?>, it will be instantiated. If it is an Object, it will be used.
Spring offers a rather simple way to customize hibernate properties with a bean:
#AutoConfiguration(after = RedissonAutoConfiguration.class, before = JpaAutoConfiguration.class)
#ConditionalOnProperty("spring.jpa.properties.hibernate.cache.use_second_level_cache")
public class HibernateCacheAutoConfiguration {
#Bean
public HibernatePropertiesCustomizer setRegionFactory(RedissonClient redisson) {
return hibernateProperties -> hibernateProperties.put(AvailableSettings.CACHE_REGION_FACTORY, new SpringBootRedissonRegionFactory(redisson));
}
}
My RegionFactory is really simple:
#AllArgsConstructor
public class SpringBootRedissonRegionFactory extends RedissonRegionFactory {
private RedissonClient redissonClient;
#Override
protected RedissonClient createRedissonClient(Map properties) {
return redissonClient;
}
#Override
protected void releaseFromUse() {
}
}
I used the redisson-starter to get a RedissonClient, hence the reference to RedissonAutoConfiguration, but you could just create an instance by hand.
It is possible, but then you need to provide a custom implementation of RegionFactory to Hibernate, which can extends RedissonRegionFactory but uses your own client instance.
How do I create and use the Redis connection that spring-boot-starter-data-redis creates? It doesn't seem like there is a Bean for RedisClient created by the default auto configuration so I'm not sure of the best way to do this.
The documentation does state that in this case you need to create the StorageProvider yourself which is fine, but can you reuse what Spring Boot has already created. I believe this would need to be a pooled connection which you would also need to enable through Spring Boot.
RedisTemplate offers a high-level abstraction for Redis interactions:
https://docs.spring.io/spring-data/data-redis/docs/current/reference/html/#redis:template
Redis autoconfiguration :
#AutoConfiguration
#ConditionalOnClass({RedisOperations.class})
#EnableConfigurationProperties({RedisProperties.class})
#Import({LettuceConnectionConfiguration.class, JedisConnectionConfiguration.class})
public class RedisAutoConfiguration {
public RedisAutoConfiguration() {
}
#Bean
#ConditionalOnMissingBean(
name = {"redisTemplate"}
)
#ConditionalOnSingleCandidate(RedisConnectionFactory.class)
public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
RedisTemplate<Object, Object> template = new RedisTemplate();
template.setConnectionFactory(redisConnectionFactory);
return template;
}
#Bean
#ConditionalOnMissingBean
#ConditionalOnSingleCandidate(RedisConnectionFactory.class)
public StringRedisTemplate stringRedisTemplate(RedisConnectionFactory redisConnectionFactory) {
return new StringRedisTemplate(redisConnectionFactory);
}
}
Here you can find the corresponding configuration properties(including connection pool default configuration).
Simple implementation example :
https://www.baeldung.com/spring-data-redis-tutorial
I would like to config the max-delivery-attempts of dead letter as described in the manual.
I tried Spring Boot with embedded ActiveMQ Artemis JMS server, but cannot figure out how to set max-delivery-attempts value.
After debugging the Configuration instance I finally find the method. Here's the code:
#Configuration
public class RedeliveryConfiguration implements ArtemisConfigurationCustomizer {
#Override
public void customize(org.apache.activemq.artemis.core.config.Configuration configuration) {
Map<String, AddressSettings> addressesSettings = configuration.getAddressesSettings();
// # is the catch all address or default address
addressesSettings.get("#").setMaxDeliveryAttempts(2);
}
}
I have a simple Spring Integration application which runs on Tomcat (v7.0.x) and consumes messages off a Websphere MQ Queue. When I un-deploy the WAR from the Tomcat server, the WAR un-deploys okay but, a JMS listener thread is left running on the Tomcat server which will still consume messages off the Websphere MQ Queue. I am therefore assuming that I am not handling the JMS listener clean up part of the application properly?
Here is the stack I am using:
Java 8
Tomcat 7.0.55
Spring Integration 4.0.4
Spring Integration Java Dsl 1.0.0.M3
In terms of my SI application's configurations, I have a JmsConfig class:
#Configuration
#ComponentScan
public class JmsConfig {
#Autowired
private Properties jndiProperties;
private ConnectionFactory mqConnectionFactory() throws NamingException {
Context ctx = new InitialContext(jndiProperties);
try {
MQQueueConnectionFactory connectionFactory = (MQQueueConnectionFactory)
ctx.lookup("jms/service/SERVICE_QCF");
return connectionFactory;
} finally {
ctx.close();
}
}
#Bean
public ConnectionFactory cachingConnectionFactory() throws NamingException {
CachingConnectionFactory connectionFactory = new CachingConnectionFactory();
connectionFactory.setTargetConnectionFactory(mqConnectionFactory());
connectionFactory.setSessionCacheSize(10);
return connectionFactory;
}
}
I have an Integration config class:
#Configuration
#EnableIntegration
public class IntegrationConfig {
#Autowired
private ConnectionFactory cachingConnectionFactory;
#Bean
public IntegrationFlow requestFlow() {
return IntegrationFlows
.from(Jms.inboundAdapter(cachingConnectionFactory).destination(
"SERVICE_QUEUE_NAME"), c -> {
c.poller(Pollers.fixedRate(100));
})
.channel("request.service.ch").get();
}
}
Web Initialiser config class:
#Configuration
public class WebInitialiser implements WebApplicationInitializer {
public void onStartup(ServletContext servletContext)
throws ServletException {
AnnotationConfigWebApplicationContext rootContext =
new AnnotationConfigWebApplicationContext();
rootContext.register(ApplicationConfig.class, JmsConfig.class,
IntegrationConfig.class, DatabaseConfig.class);
servletContext.addListener(new ContextLoaderListener(rootContext));
}
}
During the un-deploy stage I see the following in the catalina logs which may or may not be related:
SEVERE: The web application [/service-a] appears to have started a thread named [Thread-7] but has failed to stop it. This is very likely to create a memory leak.
Is there anything that I have yet NOT set or configured or annotated in order to ensure that the deployment's JMS listener thread is cleaned up from Tomcat's JVM during the WAR's un-deploy stage?
Thanks in advance,
PM.
To ensure that JMS listener threads are cleared up upon the application's un-deploy stage, I simply created a CachingConnectionFactory bean with its targetConnectionFactory being that of the MQConnectionFactory. Then, in the Spring Integration flows, I simply pass in the cachingConnectionFactory bean to the JMS adapters instead. I've updated the configs in this post to show this. Cheers, PM.
I am using spring-boot to configure jms and activemq connectivity. Due to a defect in activemq I need to set the idle timeout on the PooledConnectionFactory. This configuration is not exposed by spring-boot. How do I set it?
I have a #Bean to create a messageListenerContainer which has the connectionFactory as an argument. I can instanceof check the factory and configure it here but this seems not the correct way.
Downcasting to PooledConnectionFactory and calling setIdleTimeout is a perfectly reasonable approach, in my opinion.
If you'd prefer not to do it as part of the creation of the message listener container, you could declare your own ConnectionFactory bean while still making use of ActiveMQProperties. Something like this:
#Configuration
#EnableConfigurationProperties(ActiveMQProperties.class)
class CustomActiveMQConnectionFactoryConfiguration {
#Autowired
private ActiveMQProperties properties;
#Bean
public ConnectionFactory jmsConnectionFactory() {
ConnectionFactory connectionFactory = this.properties.createConnectionFactory();
if (connectionFactory instanceof PooledConnectionFactory) {
((PooledConnectionFactory) connectionFactory).setIdleTimeout(1000);
}
return connectionFactory;
}
}
