Java / MapStruct Java Interview questions part 2

What are the main features of MapStruct?

MapStruct focuses on making bean mapping fast, type-safe, and easy to debug.

  1. Compile-time generation - mapping code is created during the build, not at runtime.
  2. Type safety - property mismatches are caught as compiler warnings or errors.
  3. Plain Java output - the generated class is readable, debuggable code, not bytecode magic.
  4. Framework integration - supports Spring, CDI, and JSR-330 component models.
  5. Custom logic hooks - default methods, qualifiers, and lifecycle callbacks let you handle edge cases.

These features together mean MapStruct mappers run about as fast as hand-written mapping code, since there is no reflection involved at runtime.

The generated mapper implementation in MapStruct is:
Which of these is NOT a MapStruct feature?
