Is it connected to Hibernate or not? - spring

Question

Lately I found an example of Spring Boot CRUD. In the read me there is written :
This project is based on the Spring Boot project and uses these
packages :
Maven
Spring Core
Spring Data (Hibernate & MySQL)
Spring MVC (Tomcat)
Thymleaf
In the source code I do not see anything that would look like this app is somehow connected to the hibernate. Could you help me to solve this little problem? And if it is not connected to the Hibernate how can I connect CRUD like that to the Hibernate?
Thanks for your help :)

Answer 1

In example you've provided you're using spring-boot-starter-data-jpa which already contains predefined hibernate dependencies (see pom.xml).
How to work with SQL databases described in documentation section.
Basically you configure hibernate using application.properties using following prefix:
spring.jpa.properties.hibernate.*

Answer 2

for Spring boot with hibernate you can follow bellow link :-
https://github.com/netgloo/spring-boot-samples
you have to configure hibernate property and datasource property for database connection... but for example i can share some code for Spring hibernate and JPA but Spring boot with hibernate you can follow link:-
<bean id="hibernateJpaDialect" class="org.springframework.orm.jpa.vendor.HibernateJpaDialect" />
<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="packagesToScan" value="com.amstech.mayal.entity" />
<property name="jpaDialect" ref="hibernateJpaDialect" />
<property name="jpaVendorAdapter" ref="hibernateJpaVendorAdapter" />
<property name="jpaPropertyMap">
<map>
<entry key="hibernate.connection.driver_class" value="${database.jdbc.driver.class}" />
<entry key="hibernate.connection.url" value="${database.jdbc.url}" />
<entry key="hibernate.connection.username" value="${database.user}" />
<entry key="hibernate.connection.password" value="${database.password}" />
<entry key="hibernate.dialect" value="${hibernate.dialect}" />
<entry key="show_sql" value="true" />
<entry key="eclipselink.jdbc.exclusive-connection.is-lazy"
value="true" />
</map>
</property>
</bean>

Answer 3

I would suggest looking at the Spring Boot Data section of the main documentation. There is a lot less configuration that is needed and you can do it fluently and leave the xml behind. JPA + Hibernate is Spring data have become highly interlinked in boot.

Answer 4

There are multiple ways in which spring boot interact with hibernate. In the example you shared it is picking up the db properties from application.properties file and setting up the configuration. Rest of the things it will pick from the dependency provide in pom.xml.
Yes, it is connected with the hibernate. Things you need to do apart from setting up the project is to setting up a database with some username and password. And creating a db schema.Rest of the things will be done by spring boot. Make sure your db username password matches with the application file properties.
