We have modified our code from something with a direct JDG implementation (as shown below) to SpringRemoteCacheManager in an XML based configuration file and are using Spring cache:advice to define cacheable, cahce-put, cache-evict methods.
See Current code where we have control to add expiry time. We want to do similar thing with Spring - Infinispan as well. With Spring - Infinispan we do not write any application code that puts/gets objects in/from cache as its handled by Spring annotations (#Cacheable / #CachePut)
Appreciate if anyone can provide any pointers
RemoteCache<Object, Object> cache = jdgRemoteCacheManager.getCache(cacheName);
cache.put(keyName, object, 15, TimeUnit.MINUTES);
Unfortunately Spring Cache support doesn't provide such methods (see the Javadocs). So it seems the only way is to use the RemoteCache API provided by Infinispan.
Perhaps you could implement your own #Cacheable annotation and implement all the functionality you need. But that's a Spring question really...

Dears, I'd like to auto-expire Redis keys when using org.springframework.integration.redis.store.RedisMessageStore class in Spring Integration. I see some methods related to "expiry callback" but I could not find any documentation or examples yet. Any advice will be much appreciated.
#Bean
public MessageStore redisMessageStore(LettuceConnectionFactory redisConnectionFactory) {
RedisMessageStore store = new RedisMessageStore(redisConnectionFactory, "TEST_");
return store;
}
Spring Boot: 2.6.3, spring integration and spring-boot-starter-data-redis.
The RedisMessageStore does not have any expiration features. And technically it must not. The point of this kind of store is too keep data until it is used. Look at it as persistent storage. The RedisMetadataStore is based on the RedisProperties object, so it also cannot use expiration feature for particular entry.
You probably talk about a MessageGroupStoreReaper, which really calls a MessageGroupStore.expireMessageGroups(long timeout), but that's already an artificial, cross-store implementation provided by the framework. The logic relies on the group.getTimestamp() and group.getLastModified(). So, still not that auto-expiration Redis feature.
The MessageGroupStoreReaper is a process needed to be run in your application: nothing Redis-specific.
See more info in docs: https://docs.spring.io/spring-integration/docs/current/reference/html/message-routing.html#reaper
referring to quesition/answer in How to log MDC with Spring Sleuth?
I think this has/will change(d) with spring-cloud 2.0 as there is no SpanLogger or Slf4jSpanLogger anymore (or I don't find it)
Wouldn't it be nice if application properties spring.sleuth.baggage-keys and spring.sleuth.propagation-keys if set would also be put in MDC I think inside Slf4jCurrentTraceContext (as this class is currently final I cannot subclass it)
If not, how could I achieve this with spring-cloud 2.0 accordingly?
We don't want to put all entries in MDC (that really doesn't make a lot of sense). You can however either copy the Slf4jCurrentTraceContext and extend it in the way you want to (and register it as a bean) or maybe create your own implementation of CurrentTraceContext that would wrap the existing CurrentTraceContext via a Bean Post Processor and perform additional logic. I guess the first option is more preferable.
In version 2.1.0, Slf4jScopeDecorator was introduced and it will automatically add baggage values to MDC as long as they are whitelisted in the spring.sleuth.log.slf4j.whitelisted-mdc-keys configuration.
For example, if you have the following configuration:
spring.sleuth.baggage-keys=key1,key2
spring.sleuth.log.slf4j.whitelisted-mdc-keys=key2
Only the value of key2 will be automatically added MDC, but not the value of key1.

i have simple application using Spring Boot. I wanted allow method caching with JSR107 - JCache. So with help of tutorial i put together this code :
#CacheResult(cacheName = "testpoc")
public Country getCountry(Integer id){
System.out.println("---> Loading country with code '" + id + "'");
return new Country(id, "X", "Title");
}
with this POM file
...
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<version>1.4.0.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-cache</artifactId>
<version>1.4.0.RELEASE</version>
</dependency>
<dependency>
<groupId>javax.cache</groupId>
<artifactId>cache-api</artifactId>
<version>1.0.0</version>
</dependency>
</dependencies>
...
(dependency 'spring-boot-starter-web' is there for simple REST service which call getCountry method)
Everything works like documentations says - method is invoked only once.
Now i wanted to try it on WildFly 10 application server
I have modified pom file :
excluded tomcat
exluded spring-boot-starter-cache
added infinispan-jcache (because i want to use cache configured / managed by wildfly in standalone/domain.xml)
Check pom file here on pastebin.
Problem is, that i am receiving following error :
Cannot find cache named 'java:jboss/infinispan/app-cache'
(i have tried to use both JNDI assigned and name to infinispan cache configured in wildfly).
Following code created Cache object (so i can used it) :
CacheManager cacheManager = Caching.getCachingProvider().getCacheManager();
Cache<String, String> cache = cacheManager.createCache("testpoc", new MutableConfiguration<String, String>());
Question :
It is possible to use JCache method caching on WildFly 10 using Infinispan managed by WildFly ?
Or Infinispan should be used for method caching like JCache, hence JCache has "more functionality" than Infinispan.
Thank you very much
PS :It is not problem for me to put whole code on github and post link - it is few lines of code ...
There are a couple of problems with your approach so let me go through them in steps.
At first you need to use proper Infinispan setup. Infinispan bits shipped with WF should be considered as internal or private. In order to use Infinispan in your app properly - either add org.infinispan:infinispan-embedded to your deployment or install Infinispan Wildfly modules. You can find installation guide here (it's a bit outdated but still, the procedure is exactly the same - unpack modules into WF and use Dependencies MANIFEST.MF entry).
Once you have successfully installed Infinispan (or added it to your app), you need to consider whether you want to use Spring Cache or JCache. If you're only interested in using annotations - I would recommend the former since it's much easier to setup (all you need to do is to add #EnableCaching to one of your configurations). Finally with Spring Cache you will create an Infinispan CacheManager bean. An example can be found here.
Final note - if you still need to use JCache - use this manual to setup Caching Provider.
I am trying to access facebook data via spring social facebook integration using the instructions provided at http://spring.io/guides/gs/accessing-facebook.
But currently i am facing 2 type of problem
When i run example as mentioned in tutorial i get following error
No matching bean of type [org.springframework.social.facebook.api.Facebook] found for dependency
When i run this with #Configuration on FacebookConfig class, i get below mentioned error
A ConnectionFactory for provider 'facebook' has already been registered
Is there a workaround to it?
I have kept the war file with source code at https://skydrive.live.com/redir?resid=EA49CD7184E0E40!168&authkey=!AIkoKKx5-Um8AQE
What version are you using?
Try using the version 1.1.0.RELEASE
<dependency>
<groupId>org.springframework.social</groupId>
<artifactId>spring-social-facebook</artifactId>
<version>1.1.0.RELEASE</version>
</dependency>
If it not works, please try post the stacktrace printed.
You need to create a the beans to your class, please post more information like your pom.xml and your spring context configuration.
Ihad the same problem. Spring Social Facebook will automatically add connection factory based on the configuration in application.properties. This auto-configured connection factory is clashing with the one that you're trying to add. Try just to remove your connection factory you add through addConnectionFactories.
Try to use different setting to load your custom connection factory...
E.g. Instead of using OOTB keys use different keys:
#Facebook Social App Details:
# Commented below 2 OOTB Keys & Bingo it worked.
#spring.social.facebook.appId=APP_ID
#spring.social.facebook.appSecret=APP_SECRET
facebook.app.id=APP_ID
facebook.app.secret=APP_SECRET
This will resolve your problem.
I am trying to use javax.cache.CacheManager JSR107 API using EhCache as caching solutioarin provider. But I am unable to find any such resources.
As per the link at http://ehcache.org/documentation/integrations/jsr107 , it says that ehcache jsr107 is still in draft phase. Can any one please confirm if it's still the case?
Any sample code to use net sf cacheManager using JSR107 javax.cache.* classes?
Thanks,
Harish
As specified in this page:
Because JCACHE has not yet been released the JCACHE API that Ehcache
implements has been released as net.sf.jsr107cache.
This effort can be found in the Github repository. If you see JCacheManager implements javax.cache.CacheManager
Here's a better answer now the API is finalised. Stick this in your pom:
<dependency>
<groupId>org.ehcache</groupId>
<artifactId>jcache</artifactId>
<version>1.0.0</version>
</dependency>
<dependency>
<groupId>org.jsr107.ri</groupId>
<artifactId>cache-annotations-ri-guice</artifactId>
<version>1.0.0</version>
</dependency>
And you're off. Annotate with any of the annotations like this: (good luck finding the javadocs!)
#CacheResult(cacheName = "monthly")
public List<QueryResult> monthly(String prefix) {
//...
}
I agree though, the documentation sucks.
Here's more javax.cache info if you're interested.
