Using Spring beans as a key with @Cacheable annotation

Question

How to make following to work: - a spring bean that has a method that should be cached with @Cacheable annotation - another spring bean that creates keys for the cache (Key

Answer 1

In the case you have a static class function, it will work like this

@Cacheable(value = "cacheName", key = "T(pkg.beans.KeyCreatorBean).createKey(#p0)")
@Override
public List getExamples(ExampleId exampleId) {
  ...
}

with

package pkg.beans;

import org.springframework.stereotype.Repository;

public class KeyCreatorBean  {

    public static Object createKey(Object o) {
        return Integer.valueOf((o != null) ? o.hashCode() : 53);
    }

}
