MyBatis Mapper Generator

The tool analyzes a database schema or provided SQL description and outputs MyBatis artifacts: Java model classes, mapper interfaces, and XML mapping files. It targets Java development teams building persistence layers with MyBatis and seeks to standardize mappings across modules. Output artifacts align with common project conventions, enabling straightforward integration and version control. Generated code can be tailored to project conventions via configuration such as package names, base classes, Lombok options, and indentation style, making it immediately usable in builds.\n\nConceptually, generation proceeds by reading catalogs (tables, columns, keys), applying naming rules (e.g., snake_case to camelCase), translating SQL types to Java types, and rendering templates for CRUD operations and specialized queries. It can emit either XML-based mappers or annotation-based mappings, with optional dynamic SQL blocks for complex queries. The tool also produces type handlers, result maps, and optional documentation stubs. It supports multiple dialects and can import existing schemas to preserve relationships and foreign keys.\n\nThe tool's value lies in consistency, speed, and maintainability: a single configuration repository, repeatable outputs, and easy adaptation to multiple database dialects across environments. Use cases include bootstrapping a new project, migrating legacy mappers, integrating schema evolution, and enforcing uniform naming across microservices.
