Eliminating Boilerplate JDBC code with Spring Data JPA

✅ 1. Updated Maven Dependencies

Replace your current dependencies with the following:

<!-- Spring Data JPA (compatible with Jakarta EE 8 and OpenJDK 11) -->
<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-jpa</artifactId>
    <version>2.7.12</version> <!-- Jakarta EE 8 compatible, Spring 5.3.x aligned -->
</dependency>

        <!-- JPA API - Jakarta EE 8 -->
<dependency>
<groupId>jakarta.persistence</groupId>
<artifactId>jakarta.persistence-api</artifactId>
<version>2.2.3</version> <!-- Aligned with Jakarta EE 8 (JPA 2.2) -->
</dependency>

        <!-- SLF4J API for logging -->
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.7.36</version>
</dependency>

        <!-- SLF4J Simple implementation (or Logback/log4j if preferred) -->
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-simple</artifactId>
<version>1.7.36</version>
<scope>runtime</scope>
</dependency>

        <!-- Hibernate Core as JPA provider (compatible with JDK 11 & Jakarta EE 8) -->
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>5.6.15.Final</version>
</dependency>

        <!-- Optional: MariaDB JDBC Driver -->
<dependency>
<groupId>org.mariadb.jdbc</groupId>
<artifactId>mariadb-java-client</artifactId>
<version>2.7.9</version>
</dependency>

Note:

• spring-data-jpa:2.7.x is the last line of Spring Data compatible with Spring Framework 5.3.x and Jakarta EE 8 (before Spring Boot 3.x moves to Jakarta EE 9+).
• Jakarta EE 8 still uses jakarta.persistence with package names like javax.persistence, but artifact group IDs are now under jakarta.*.
