Spring Boot Anleitung 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.
Warum es wichtig ist
Spring Data reduces boilerplate with repository interfaces and query derivation. The right database choice affects JPA features, connection pooling, and cloud deployment patterns.
Wichtige Überlegungen
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.
