I'm a little bit confused by hibernates (version 5.1) naming strategy - namely it changes my table name and I'd like to avoid that. Also - spring.jpa.hibernate.naming_strategy seems to be deprecated according to intelij, but I can't find a (nother) way of configuring it correctly.
I have the following configuration in application.properties:
spring.jpa.hibernate.naming_strategy=org.hibernate.cfg.EJB3NamingStrategy
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
spring.jpa.properties.hibernate.enable_lazy_load_no_trans=true
spring.jpa.properties.hibernate.current_session_context_class=thread
The first one is marked as depracted, as said.
Now I have an entity:
@Entity
@Table(name = "usaUploadTable", schema = "usertable201", catalog = "")
public class UsaUploadTable {
....
}
The table name is, like in @Table(name = "") usaUploadTable.
Now when I run my application, I get
Table 'usertable201.usa_upload_table' doesn't exist
which is correct - it isn't named like how hibernate is changing it.
What can I do to make hibernate use my table name correctly?
Edit:
I've also tried
DefaultNamingStrategy
ImprovedNamingStrategy
All of them change it
Versions:
spring-boot-1.4.0.RELEASE
hibernate 5.1
javax-transaction-api 1.2
hibernate-validator 5.2.4
javassist 3.20
The problem lies in spring-boot-1.4 - it seems like they have changed the properties (or whatever) I've now found this answer ImprovedNamingStrategy no longer working in Hibernate 5, but it still didn't resolve correctly. So I have changed the code a little to not use the underscore method and to extend the newly introduced class SpringPhysicalNamingStrategy:
package com.foo;
import org.hibernate.boot.model.naming.Identifier;
import org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl;
import org.hibernate.engine.jdbc.env.spi.JdbcEnvironment;
import java.io.Serializable;
import java.util.Locale;
public class RealNamingStrategyImpl extends org.springframework.boot.orm.jpa.hibernate.SpringPhysicalNamingStrategy implements Serializable {
public static final PhysicalNamingStrategyImpl INSTANCE = new PhysicalNamingStrategyImpl();
@Override
public Identifier toPhysicalTableName(Identifier name, JdbcEnvironment context) {
return new Identifier(name.getText(), name.isQuoted());
}
@Override
public Identifier toPhysicalColumnName(Identifier name, JdbcEnvironment context) {
return new Identifier(name.getText(), name.isQuoted());
}
}
And in application.properties I've changed the deprecated line to
spring.jpa.properties.hibernate.physical_naming_strategy=<package>.RealNamingStrategyImpl
Now it uses exactly the table and column names as I have them in my entity files.
