public class Main {

public static void main(String[] args){

Configuration builder = new ConfigurationBuilder().persistence().addStore(JpaStoreConfigurationBuilder.class).persistenceUnitName("myPersistenceUnit").entityClass(Details.class)

.build();

builder.invocationBatching().enabled();

EmbeddedCacheManager cacheManager = new DefaultCacheManager(builder);

cacheManager.defineConfiguration("userCache", builder);

Cache<String, Details> userCache = cacheManager.getCache("userCache");

userCache.put("zac", new Details());
