Is using hibernate type property names when using spring boot a good approach - spring-boot

Question

In my current codebase, I have a RestController, and I am using hibernate with it. As of now, I am using the same hibernate configuration which one would usually use
<?xml version="1.0" encoding="UTF-8" ?>
<hibernate-configuration xmlns="http://www.hibernate.org/xsd/orm/cfg">
<session-factory>
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="hibernate.connection.url">jdbc:mysql://localhost</property>
<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
<property name="hibernate.hbm2ddl.auto">update</property>
</session-factory>
</hibernate-configuration>
Also, in my pom.xml, I have added:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>8.0.28</version>
</dependency>
But to get this working I had to add the attribute exclude like this :
#SpringBootApplication(exclude = {DataSourceAutoConfiguration.class })
Otherwise, it was throwing some error. Another issue I noticed was even though
hbm2ddl.auto is set to true, which would have created the tables in a simple hibernate application. But it's not happening now. It throws an error if the table is not there but seems to be working fine if it's there.
I changed the MySQL dialect in the hibernate.cfg.xml to :
org.hibernate.dialect.MySQL8Dialect
And now it's automatically creating the table. That's weird when I was using the same hibernate code without spring boot the earlier Dialect was working
This is the main code that starts the application:
#SpringBootApplication(exclude = DataSourceAutoConfiguration.class)
public class SpringServerMain {
public static void main(String[] args) {
ApplicationContext context = SpringApplication.run(SpringServerMain.class, args);
}
}
