Best practices for using MapStruct with constructor-based mapping to achieve compile-time safety. When constructors change, mappings fail to compile — no runtime surprises.

Use constructors, not setters. This gives you compile-time errors when fields change.

Records naturally enforce this. For mutable entities, use the @Default annotation.

基於構造函數的 MapStruct 映射可確保 Jakarta EE 中的編譯時安全。在實現 DTO 映射或使用 @Default 註釋時使用。 來源：emvnuel/skill.md。
