如何优化遗留系统的代码重构效率?

2025-08-20 518

遗留系统现代化重构加速方案

老旧代码库重构面临理解成本高、测试覆盖率低等挑战。Qwen Code提供全方位重构支持:

  • 架构透视:自动生成模块依赖图和接口契约文档
  • 安全重构:确保语义等价的代码转换,提供修改影响范围分析
  • 测试保障:为重构代码自动生成边界条件测试用例

实施路线图:

  1. 系统分析阶段:qwen "Analyze system architecture and identify tech debt" > audit_report.md
  2. 优先级评估:qwen "Rank refactoring candidates by ROI" --criteria=complexity,usage
  3. 安全重构:qwen "Refactor this module with guardrail tests" --strategy=extract-class

针对性解决方案:

  • 巨型函数处理:使用--refactor-type=extract-method参数分解
  • 模式替换:qwen "Replace singleton with dependency injection"
  • Type Safety:qwen "Add TypeScript types to this JS module" --strictness=high
