Spring-Boot-JPA-Multi-Databases-And-Rollback-Transaction

A Proof of Concept demonstrating how to configure multiple relational databases in a single Spring Boot application using Spring Data JPA, dedicated HikariCP connection pools, and separate transaction managers.

The project connects to:

MySQL
MariaDB
PostgreSQL
Oracle Database

It also demonstrates:

Transactions scoped to a single database
Coordinated rollback across multiple local transaction managers using ChainedTransactionManager
Explicit mapping between repositories, entities, EntityManagerFactory instances, and transaction managers

Important

This repository is an educational, legacy Proof of Concept based on Java 8 and Spring Boot 2.3.0.BUILD-SNAPSHOT. ChainedTransactionManager is not an XA or two-phase commit transaction manager and has been deprecated since Spring Data 2.5. Do not treat this example as a guarantee of atomic distributed transactions in production.

Overview

Spring Boot normally auto-configures one primary DataSource, one JPA EntityManagerFactory, and one transaction manager.

When an application connects to multiple databases, each database should have its own infrastructure:

DataSource
HikariCP connection pool
JPA properties
EntityManagerFactory
Repository package
PlatformTransactionManager

This project creates that infrastructure separately for MySQL, MariaDB, PostgreSQL, and Oracle.

For operations that affect only one database, the service selects the matching transaction manager:

@Transactional(BeanIds.TRANSACTION_MANAGER_MYSQL)

For the demonstration that writes to all four databases, the service selects a chained transaction manager:

@Transactional(BeanIds.TRANSACTION_MANAGER_CHAINED)

Key Features

Four independently configured relational databases
One HikariCP connection pool per database
One EntityManagerFactory per database
One JpaTransactionManager per database
Repository scanning isolated by package
Dedicated database property files
REST endpoints for testing each transaction manager
A multi-database rollback demonstration
Automatic schema updates through Hibernate configuration
Transaction and connection-pool debug logging

    OracleEMF --> Oracle[(Oracle)]

How the Configuration Works

1. Spring Boot database auto-configuration is disabled

The application manually defines every database-related bean, so the default JDBC and JPA auto-configuration is excluded in application.properties.

spring.autoconfigure.exclude[0]=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration
spring.autoconfigure.exclude[1]=org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration

2. Each database has a dedicated property file

Database	Configuration file
MySQL	`db_mysql.properties`
MariaDB	`db_maria.properties`
PostgreSQL	`db_postgresql.properties`
Oracle	`db_oracle.properties`

Each repository configuration loads its property file with @PropertySource.

``java @PropertySource("classpath:db_mysql.properties")


### 3. Repository packages are isolated

Each configuration class limits JPA repository scanning to the package belonging to that database.

```java
@EnableJpaRepositories(
    basePackages = "com.tirmizee.jpa.mysql.repositories",
    entityManagerFactoryRef = BeanIds.ENTITY_MANAGER_FACTORY_MYSQL,
    transactionManagerRef = BeanIds.TRANSACTION_MANAGER_MYSQL
)

This prevents a repository from accidentally using another database's EntityManagerFactory or transaction manager.

4. Each database owns its JPA infrastructure

The configuration for each database creates:

HikariDataSource
        ↓
LocalContainerEntityManagerFactoryBean
        ↓
JpaTransactionManager

5. Services select the required transaction manager

A single-database service explicitly references its database transaction manager:

@Transactional(BeanIds.TRANSACTION_MANAGER_MYSQL)
public Mockup save(MysqlDTO dto) {
    // ...
}

The multi-database service references the chained transaction manager:

@Transactional(BeanIds.TRANSACTION_MANAGER_CHAINED)
public void save(String name) {
    // Writes to Oracle, MariaDB, MySQL, and PostgreSQL.
}
