Problem using @Cacheable with jcs

[claudio_br]

Hi,

I am trying use the spring-modules-cache (0.9 version) with jcs, but it does not work.
I wrote this class:

package com;

import java.util.ArrayList;
import java.util.List;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springmodules.cache.annotations.CacheFlush;
import org.springmodules.cache.annotations.Cacheable;

public class TigerCacheableService {
	
  List<String> names = new ArrayList<String>();
	
  public List<String> getNames() {
    return names;
  }

  public void setNames(List<String> names) {
    this.names = names;
  }

  @Cacheable(modelId = "testCaching")
  public final String getName(int index) {
    System.out.println("Processing getName");
    return names.get(index);
  }

  @CacheFlush(modelId = "testFlushing")
  public final void updateName(int index, String name) {
    System.out.println("Processing updateName");
  }
	
  public static void main(String[] args) {
    ApplicationContext applicationContext = new ClassPathXmlApplicationContext("/application-context.xml");
    TigerCacheableService tigerCacheableService = (TigerCacheableService)applicationContext.getBean("cacheableService");
    System.out.println(tigerCacheableService.getName(0));
    System.out.println(tigerCacheableService.getName(0));
    System.out.println(tigerCacheableService.getName(0));
  }

}

With this jcs-config.properties:

jcs.default=
jcs.default.cacheattributes=org.apache.jcs.engine.CompositeCacheAttributes
jcs.default.cacheattributes.MaxObjects=1000
jcs.default.cacheattributes.MemoryCacheName=org.apache.jcs.engine.memory.lru.LRUMemoryCache
jcs.default.cacheattributes.UseMemoryShrinker=true
jcs.default.cacheattributes.MaxMemoryIdleTimeSeconds=3600
jcs.default.cacheattributes.ShrinkerIntervalSeconds=60
jcs.default.cacheattributes.MaxSpoolPerRun=500
jcs.default.elementattributes=org.apache.jcs.engine.ElementAttributes
jcs.default.elementattributes.IsEternal=false

And with this application-context.xml:

<?xml version="1.0" encoding="UTF-8"?>

        <value>Luke Skywalker</value>
        <value>Leia Organa</value>
      </list>
    </property>
  </bean>

</beans>

In the System.out, I got:

Processing getName
Luke Skywalker
Processing getName
Luke Skywalker
Processing getName
Luke Skywalker

But what was expected:

Processing getName
Luke Skywalker
Luke Skywalker
Luke Skywalker

In the log I did not see any exception or error
Can someone help me?
Thanks

Hi,

I solved the problem.
I added in my application-context.xml the follow line:

<bean id="autoproxy" class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator" />

In my class I changed from:

  @Cacheable(modelId = "testCaching")
  public final String getName(int index) {
    System.out.println("Processing getName");
    return names.get(index);
  }

  @CacheFlush(modelId = "testFlushing")
  public final void updateName(int index, String name) {
    System.out.println("Processing updateName");
  }

to:

@Cacheable(modelId = "testCaching")
  public String getName(int index) {
    System.out.println("Processing getName");
    return names.get(index);
  }

  @CacheFlush(modelId = "testFlushing")
  public void updateName(int index, String name) {
    System.out.println("Processing updateName");
  }

The code worked. Yes!
Bye

Hi,

Has anybody got the solution of this problem? I included spring 2.5.6-jar and it is now not giving exception and code is working but caching is not happening.

Thanks,
