Document that spring.jpa.hibernate.naming-strategy has default value

[php-coder]

Please document in example application.yml that spring.jpa.hibernate.naming_strategy property has default value org.springframework.boot.orm.jpa.hibernate.SpringNamingStrategy.

Also as far I can see setting property spring.jpa.properties.hibernate.ejb.naming_strategy doesn't work and you have to use spring.jpa.hibernate.naming_strategy property instead (see HibernateJpaAutoConfigurationTests.testCustomNamingStrategyViaJpaProperties. I believe that it's also should be documented somewhere, because it's unexpected behavior.

I believe this issue can be closed. Hibernate 4 is no longer supported since Spring Boot 1.5 (see release notes).

Thus, both properties spring.jpa.hibernate.naming_strategy and spring.jpa.hibernate.naming_strategy are no longer relevant. And the docs have been properly updated to describe the new Hibernate 5 naming strategy properties.

However, while at it, I submitted PR #9763 which makes the current docs a little clearer by mentioning both new properties spring.jpa.hibernate.naming.physical-strategy and spring.jpa.hibernate.naming.implicit-strategy and the fact that these came with Hibernate 5.
