JavaFactory: Predictable AI-Powered Java Code Generation

JavaFactory is a tool leveraging LLMs to automatically generate repetitive Java code, offering more predictable and stable results than traditional AI code generators. It relies on two core components: Pattern Definition, where units of work (e.g., test generation, implementation generation) are defined in natural language; and Annotation-Based Reference Collection, explicitly specifying required classes using annotations. These defined patterns are reusable for generating various code types (implementations, tests, fixtures). A demo showcases generating 400 lines of code with all tests passing in just 20 seconds. Ideal for developers in repetitive, structured environments (e.g., layered architectures), JavaFactory automates repetitive tasks like dao-repository generation, allowing developers to focus on core logic.
