Spring Boot Guide

Best Databases for Spring Boot (2026)

Compare the best database solutions for Spring Boot. We review PostgreSQL, MySQL, and managed databases with Spring Data JPA integration.

Spring Data JPA provides powerful repository abstractions for database access. We've evaluated managed and self-hosted databases that work well with Spring Boot's data layer.

Pourquoi C'est Important

Spring Data reduces boilerplate with repository interfaces and query derivation. The right database choice affects JPA features, connection pooling, and cloud deployment patterns.

Considérations Clés

Spring Data JPA

JPA with Hibernate is the standard. Works with any JDBC-compatible database. Repository pattern reduces boilerplate.

Connection Pooling

Spring Boot uses HikariCP by default. Configure pool size for your workload. Managed databases may require specific settings.

Flyway/Liquibase

Use Flyway or Liquibase for migrations. Both integrate with Spring Boot auto-configuration.

R2DBC for Reactive

For reactive applications, use Spring Data R2DBC instead of JPA. PostgreSQL and MySQL have R2DBC drivers.

Cloud SQL Proxy

For GCP, use Cloud SQL Proxy. For AWS, configure RDS connection with proper security groups.

Questions Fréquemment Posées

Should I use JPA or JDBC with Spring Boot? ▼

Use JPA (Spring Data JPA) for most applications—it reduces boilerplate significantly. Use Spring Data JDBC for simpler domain models. Use raw JDBC Template only for complex queries.

How do I run migrations in Spring Boot? ▼

Use Flyway or Liquibase. Add the starter dependency and put migrations in src/main/resources/db/migration. They run automatically on startup.

What about connection pooling? ▼

Spring Boot uses HikariCP by default. Configure spring.datasource.hikari.* properties. For serverless databases, you may need lower pool sizes.

Can I use PlanetScale with foreign keys? ▼

PlanetScale doesn't support foreign keys for online schema changes. Use application-level referential integrity. JPA relationships still work, just no DB-level constraints.
