In the previous tutorial we have seen, what is Spring Data JPA and how it makes our life easy.
Now, in this tutorial we will see, how we can implement it in our Spring Boot Project.
So, the only thing we need to do is, add the Spring Data Starter JPA,
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-jpa</artifactId> </dependency>
To the Maven file (i.e. pom.xml).
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>org.example</groupId>
<artifactId>springbootproject</artifactId>
<version>1.0-SNAPSHOT</version>
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.4.1</version>
</parent>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
</dependencies>
</project>
And thats all!
So, now the question is, do you need to include the dependency for Hibernate?
Well! The answer is NO. As Spring Data Starter JPA itself comes with the dependency for the following :
So the Spring Data Starter JPA comes loaded with the above dependencies.
Now, the next question that pops us in our mind is, we need a database where we can create a table and save the details of a student.
Well! We would be using H2 database in this case.
