Spring Boot + JPA : Column name annotation ignored

Question

I have a Spring Boot application with dependency spring-boot-starter-data-jpa. My entity class has a column annotation with a column name. For example:

@Column(name="TestName")
private String testName;

SQL generated by this created test_name as the columns name. After looking for a solution I have found that spring.jpa.hibernate.naming_strategy=org.hibernate.cfg.EJB3NamingStrategy solved the problem (column name is taken from column annotation).

Still, my question is why without naming_strategy set to EJB3NamingStrategy JPA is ignoring column annotation? Maybe hibernate dialect has something to do with it? I'm connecting to MS SQL 2014 Express and my logs contain:

Unknown Microsoft SQL Server major version [12] using SQL Server 2000 dialect
Using dialect: org.hibernate.dialect.SQLServerDialect 

Answer 1

For hibernate5 I solved this issue by puting next lines in my application.properties file:

spring.jpa.hibernate.naming.implicit-strategy=org.hibernate.boot.model.naming.ImplicitNamingStrategyLegacyJpaImpl
spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl
