Dynamic-datasource is a Spring Boot starter that enables rapid integration of multiple datasources in applications.
The tool addresses the complexity of managing multiple databases by providing a framework for datasource grouping that supports various architectural patterns including pure multi-database setups, read-write separation, primary-replica configurations, and hybrid modes. It works by allowing developers to define multiple datasources through configuration and switch between them dynamically at runtime using annotations and method-level declarations. The approach includes support for datasource encryption, lazy loading, and dynamic addition or removal of datasources after application startup.
Teams should adopt this tool when building applications that require multi-database support, read-write splitting, or distributed data access patterns. It suits projects using MyBatis or MyBatis-Plus that need to route queries to different databases based on business logic. The tool provides integration with popular connection pooling libraries including Druid, HikariCP, BeeCp, and DBCP2, and offers compatibility with related frameworks like Quartz, ShardingJdbc, and Seata for distributed transactions. It supports multiple Spring Boot versions and Java versions, making it adaptable to both legacy and modern Spring Boot applications.
The project maintains active development with regular updates across multiple Spring Boot major versions. The codebase shows consistent refinement of core features including the annotation system and dynamic datasource switching mechanisms. Documentation is actively maintained with a dedicated documentation site, and the project welcomes community contributions through a defined contribution process.
