Spring Ehcache3 cause exception with key-type and value-type

Question

my issue is the same of this Spring Ehcache3 cause exception with with key-type and value-type, the only difference is that I don't have an .xml file, I have this CacheConfig instead:

@Configuration
@EnableCaching
public class CacheConfig {

    @Bean
    public CacheManager cacheManager() {
        // creation of cache configuration
        CacheConfiguration<String, String> cacheConfiguration = CacheConfigurationBuilder
                .newCacheConfigurationBuilder(
                        String.class, String.class,
                        ResourcePoolsBuilder.heap(1000).build()
                ).build();

        // fetching cacheManager
        CachingProvider cachingProvider = Caching.getCachingProvider();
        CacheManager cacheManager = cachingProvider.getCacheManager();

        // parsing ehcache configuration to something SpringBoot will understand
        javax.cache.configuration.Configuration<String, String> configuration = Eh107Configuration.fromEhcacheCacheConfiguration(cacheConfiguration);

        // creating as many caches as you want
        cacheManager.createCache("serviceHostName", configuration);

        // add shutdown hook to close cacheManager
        Runtime.getRuntime().addShutdownHook(new Thread(cacheManager::close));

        // return Bean
        return cacheManager;
    }
}

But when I deploy project, I have this exception:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'cacheManager' defined in class path resource [org/springframework/boot/autoconfigure/cache/JCacheCacheConfiguration.class]: Cache [serviceHostName] specifies key/value types. Use getCache(String, Class, Class)....
    
Caused by: java.lang.IllegalArgumentException: Cache [serviceHostName] specifies key/value types. Use getCache(String, Class, Class)
    at org.ehcache.jsr107.Eh107CacheManager.getCache(Eh107CacheManager.java:271) ~[ehcache-3.0.0.jar:3.0.0 6973aca181d2b3e0010945a89933f3c99f4460c5]....

What is need to do, that I can use own key type and value types?
