Moving Spring Boot 1.3 to 1.4, Sleep 4 to 5, Pascal Issues

Question

I created Spring Boot 1.3.5 POC with Spring JPA and Hibernate data (4.3.11.Final in this version of Spring Boot). My backend database is Microsoft SQL Server, and our standard naming convention for database objects is a pascal case (e.g. MySchema.MyTable.MyColumn). I used the javax.persistence.Table and javax.persistence.Column annotations to set the names and added spring.jpa.hibernate.naming-strategy = org.hibernate.cfg.EJB3NamingStrategy to the application.properties file.

Everything worked perfectly. I even upgraded to Spring Boot 1.3.6 without any problems.

Now I switched to Spring Boot 1.4.0.RELEASE, which uses Hibernate 5.0.9.Final, and the spring.jpa.hibernate.naming-strategy property is deprecated in favor of spring.jpa. hibernate.naming.strategy. I changed this property name, but left the value EJB3NamingStrategy. I also changed other obsolete elements:

• org.springframework.boot.orm.jpa.EntityScan to org.springframework.boot.autoconfigure.domain.EntityScan
• org.springframework.boot.context.web.SpringBootServletInitializer to org.springframework.boot.web.support.SpringBootServletInitializer
• org.springframework.boot.test.SpringApplicationConfiguration to org.springframework.boot.test.context.SpringBootTest (in my test classes)

Now the created SQL uses the default camel case to emphasize the naming convention, not the pascal case I had with EJB3NamingStrategy.
