✓ 应当这么做
- ✓ Keep constructors and DTOs immutable; prefer records where the language version allows
- ✓ Wire dependencies through the container, never through static singletons
- ✓ Make every REST boundary explicitly validate its input
✕ 常见反模式
- ✕ Field injection or hidden static state in services
- ✕ Swallowing exceptions in catch blocks with an empty body
- ✕ N+1 query patterns hidden inside entity mappings
◎ 交付前验证
- ◎ Unit and slice tests pass; integration tests run against a real or containerised datastore
- ◎ No new deprecation warnings from the compiler
- ◎ Transaction boundaries re-checked on any new write path
