I am trying to use a result of method call to a spring bean as a part of the cache key, but that doesn't seem to work.
@Inject
private KeyCreatorBean keyCreatorBean;
@Cacheable(value = "cacheName", key = "{@keyCreatorBean.createKey, #p0}")
@Override
public List<Examples> getExamples(ExampleId exampleId) {
Results in this kind of stack trace:
org.springframework.expression.spel.SpelEvaluationException: EL1008E:(pos 1): Field or property 'keyCreatorBean' cannot be found on object of type 'org.springframework.cache.interceptor.CacheExpressionRootObject'
