p3c-coding-style

What problem does it solve?

This skill consolidates and enforces the Alibaba Java coding style rules, ensuring consistent naming, formatting, constants, and comment guidelines across a codebase.

Core Features & Use Cases

• Naming conventions: class names in UpperCamelCase with exceptions for DO/BO/DTO/VO/AO/PO, and methods/fields in lowerCamelCase.
• Constant and array rules: constants must be uppercase with underscores; arrays defined with type[] syntax; boolean fields in POJOs avoid using is prefixes to prevent serialization issues.
• Documentation and structure: abstract/base prefixes for abstract classes; exceptions named with Exception suffix; services/DAOs exposed as interfaces, with Impl implementations; enum naming guidance.
• Use case: you want a multi-module Java project to maintain consistent style, reduce onboarding time, and simplify code reviews.

Quick Start

Adopting these guidelines involves configuring your IDE and build tools to enforce the rules, introducing a style-checking configuration (e.g., PMD/Checkstyle) aligned with these conventions, and gradually refactoring existing code to meet the standards.
