Spring JPA+Hibernate not able to fetch record using findAll() of JPARepository - spring

Question

I have created configuration using below code :
#Configuration
#EnableTransactionManagement
#ComponentScan("Name of package")
#EnableJpaRepositories("Name of package")
public class Config {
private static final String PROPERTY_NAME_HIBERNATE_DIALECT = "hibernate.dialect";
private static final String PROPERTY_NAME_ENTITYMANAGER_PACKAGES_TO_SCAN = "Name of package";
#Bean
public DataSource dataSource() {
DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setDriverClassName("Driver Name");
dataSource.setUrl("Url");
dataSource.setUsername("UserName");
dataSource.setPassword("Password");
return dataSource;
}
#Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();
entityManagerFactoryBean.setDataSource(dataSource());
entityManagerFactoryBean.setPersistenceProviderClass(HibernatePersistenceProvider.class);
entityManagerFactoryBean.setPackagesToScan(PROPERTY_NAME_ENTITYMANAGER_PACKAGES_TO_SCAN);
entityManagerFactoryBean.setJpaProperties(hibProperties());
entityManagerFactoryBean.setJpaVendorAdapter(new HibernateJpaVendorAdapter());
return entityManagerFactoryBean;
}
private Properties hibProperties() {
Properties properties = new Properties();
properties.put(PROPERTY_NAME_HIBERNATE_DIALECT, "org.hibernate.dialect.DB2Dialect");
properties.put("hibernate.default_schema","Schema Name");
return properties;
}
#Bean
public PlatformTransactionManager transactionManager(EntityManagerFactory emf){
JpaTransactionManager transactionManager = new JpaTransactionManager();
transactionManager.setEntityManagerFactory(emf);
return transactionManager;
}
#Bean
public PersistenceExceptionTranslationPostProcessor exceptionTranslation(){
return new PersistenceExceptionTranslationPostProcessor();
}
}
There is an custom repository interface that implements JPARepository.
I have autowired the custom repository in controller and tried to call findAll().But the method returns 0 although there are 3 records in DB.
I am using spring web for rest service calls.
Entity class is created with #Entity and #Table annotations.It has an embedded key which is annotated using #EmbeddedId annotation.
#Repository
public interface EntityRepository extends JpaRepository<EntityTable, Long> {
#SuppressWarnings("unchecked") EntityTable save(EntityTable entityTable);
}
Entity table is the name of my table mapped with db table.
