Cannot find the cache named xxx for the builder in spring boot application

Question

I have a Spring boot application where I want to use spring bot cache on a repository method.I have specified @EnableCaching annotaion in my spring boot app, When I try to use @Cacheable annotation on my repository method, it throws error like

java.lang.IllegalArgumentException: Cannot find cache named 'cache' for Builder[public abstract java.util.Optional myRepoMethod(java.lang.String,java.lang.String)] caches=[cache] | key='' | keyGenerator='' | cacheManager='' | cacheResolver='' | condition='' | unless='' | sync='false' at org.springframework.cache.interceptor.AbstractCacheResolver.resolveCaches(AbstractCacheResolver.java:84) ~[spring-context-5.0.6.RELEASE.jar:5.0.6.RELEASE] at org.springframework.cache.interceptor.CacheAspectSupport.getCaches(CacheAspectSupport.java:224) ~[spring-context-5.0.6.RELEASE.jar:5.0.6.RELEASE] at org.springframework.cache.interceptor.CacheAspectSupport$CacheOperationContext.(CacheAspectSupport.java:669) ~[spring-context-5.0.6.RELEASE.jar:5.0.6.RELEASE] at org.springframework.cache.interceptor.CacheAspectSupport.getOperationContext(CacheAspectSupport.java:237) ~[spring-context-5.0.6.RELEASE.jar:5.0.6.RELEASE] at org.springframework.cache.interceptor.CacheAspectSupport$CacheOperationContexts.(CacheAspectSupport.java:570) ~[spring-context-5.0.6.RELEASE.jar:5.0.6.RELEASE] at org.springframework.cache.interceptor.CacheAspectSupport.execute(CacheAspectSupport.java:317) ~[spring-context-5.0.6.RELEASE.jar:5.0.6.RELEASE] at org.springframework.cache.interceptor.CacheInterceptor.invoke(CacheInterceptor.java:61) ~[spring-context-5.0.6.RELEASE.jar:5.0.6.RELEASE] at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:185) ~[spring-aop-5.0.6.RELEASE.jar:5.0.6.RELEASE] at org.springframework.aop.framework.JdkDynamicAopProxy.invoke(JdkDynamicAopProxy.java:212) ~[spring-aop-5.0.6.RELEASE.jar:5.0.6.RELEASE] at com.sun.proxy.$Proxy140.findByUserIdAndProduct(Unknown Source) ~[?:?]

I don't know where I have missed out !!

My repository method looks like ,

@Cacheable("cache")
Optional<ModelClass> findByUserIdAndProduct(String userId, String product);

because of you don't add

@Bean
public CacheManager cacheManager() {
    SimpleCacheManager cacheManager = new SimpleCacheManager();
    List<CaffeineCache> caffeineCaches = new ArrayList<>();
    for (CacheConstant cacheType : CacheConstant.values()) {
        caffeineCaches.add(new CaffeineCache(cacheType.toString(),
                Caffeine.newBuilder()
                        .expireAfterWrite(cacheType.getExpires(), TimeUnit.SECONDS)
                        .maximumSize(cacheType.getMaximumSize())
                        .build()));
    }
    cacheManager.setCaches(caffeineCaches);
    return cacheManager;
}
