This article walks through configuring multiple data sources in Spring Boot 3, covering @Primary usage, YAML datasource definitions, bean setup with DataSourceBuilder, JPA entity manager factories, transaction managers, and unit testing to ensure each datasource operates independently.
This article explains how to integrate Spring Boot with MyBatis, configure a single Druid data source, implement a dynamic routing data source for multiple databases, and use custom annotations and AOP to switch databases at runtime, including full code examples and transaction management.
This guide walks through setting up a Spring Boot 2.4.12 project with JDK 1.8, Oracle, and two data sources—master and slave—covering Maven dependencies, application.yml settings, custom property classes, HikariDataSource beans, JPA EntityManagerFactory, MyBatis SqlSessionFactory, mapper scanning, and testing entity creation to verify successful configuration.
This guide walks through setting up a Spring Boot 2.1.4 application with JDK 1.8, Oracle, and HikariCP to use separate master and slave data sources, covering Maven dependencies, YAML configuration, custom property classes, JPA EntityManager factories, MyBatis SqlSession factories, mapper scanning, and sample entity definitions.
This tutorial explains how to configure Spring Boot with a single Druid data source, extend it to multiple dynamic data sources using AbstractRoutingDataSource, and seamlessly integrate MyBatis, including custom annotations, AOP switching, thread‑local isolation, and transaction management for robust multi‑database applications.
Learn step-by-step how to set up and test multiple data sources in a Spring Boot application using MyBatis, covering property configuration, DataSource beans, mapper scanning, entity definitions, and verification through unit tests with complete code examples and key configuration notes.
This guide explains step‑by‑step how to set up two separate databases in a Spring Boot application, configure Spring Data JPA for each, create the necessary configuration classes, and verify the setup with a simple integration test.
