Alguém teria alguma dica do que pode ser esse erro?

Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean]: Factory method ‘LocalContainerEntityManagerFactoryBeanentityManagerFactory’ threw exception; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named ‘dataSource’ available  
org.springframework.beans.factory.support.ConstructorResolver.instantiateUsingFactoryMethod(ConstructorResolver.java:590)

Estou no capítulo 3 do Livro - Cadastro de Produto e não consigo prosseguir.

Olá Demitrius, eu ainda não li este livro mas reveja a parte que configura o dataSource ele não está disponível para o Spring.
