Cannot find cache named '' for CacheableOperation[] caches

Question

My error is :

Exception in thread "main" java.lang.IllegalArgumentException: Cannot find cache named 'getActionsBycasId' for CacheableOperation[public java.util.List com.codinko.database.DataBaseConnection.getActionsByCasId(int)] caches=[getActionsBycasId] | key='' | keyGenerator='' | cacheManager='' | cacheResolver='' | condition='' | unless=''

My function is :

@Cacheable("getActionsBycasId")
public List<SMSAction> getActionsByCasId(int casId){
    System.out.println("Inside getActionsByCasId");
    //My logic
    return list;
}    

when i add below on ehcache.xml then above error not comes but can't know why this error come .

<cache name="getActionsBycasId" maxElementsInMemory="50" eternal="false"
    overflowToDisk="false" memoryStoreEvictionPolicy="LFU" />    

Is this above configuration required in ehcache.xml file even though i used annotation ????

Answer 1

Try this :

@Bean
public CacheManager cacheManager() {
    SimpleCacheManager cacheManager = new SimpleCacheManager();
    List<Cache> caches = new ArrayList<Cache>();
    caches.add(new ConcurrentMapCache("getActionsBycasId"));
    cacheManager.setCaches(caches);
    return cacheManager;
}
