Doubt how to configure Spring Data with Hibernate

Question

How to set up Spring Data + Hibernate

Hello everyone,

I’m new here in stackoverflow and also in java web development. I am etudando some things of Spring Frameork and I am with a doubt of how I can configure Spring Data in my Dynamic Project.

Below follows my acquisitions of configuration and architecture. If you could help me, I’d really appreciate it.

Architecture

persistence.xml

<persistence-unit name="cleanUpUP" transaction-type="RESOURCE_LOCAL">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <properties>

        <property name="dialect" value="org.hibernate.dialect.MySQLDialect" />

        <!-- Configuracoes do Hibernate -->
        <property name="hibernate.hbm2ddl.auto" value="update" />
        <property name="hibernate.show_sql" value="true" />
        <property name="hibernate.format_sql" value="true" />
        <property name="org.hibernate" value="info" />
        <property name="org.hibernate.SQL.level" value="debug" />
        <property name="org.hibernate.type.level" value="debug" />

    </properties>

</persistence-unit>

If you could help me out and give me a tip I’d really appreciate it

Answer 1

Wellington,

If the project is still early, I strongly advise you to use Spring Boot with Spring Data JPA, it abstracts a lot the settings of Spring and it is very easy to configure Spring Data JPA, take a look at this link: https://spring.io/guides/gs/accessing-data-jpa/

If you are interested and have doubts I can help you.

Hugs

Answer 2

Related to JPA, are the "dependencies" (in Portuguese):

DEPENDENCY MANAGEMENT SYSTEM

 <dependencies> 
    <dependency> 
        <groupId> org.springframework.data </groupId> 
        <artifactId> spring-data-jpa </artifactId> 
        <version> 1.7.1.RELEASE </version> 
    </dependency> 
</dependencies>
