# kora-mapstruct — MapStruct mappers as Kora components > **Kora sub-skill — obey the [kora-v1 meta rules](../../SKILL.md) on every task:** **R0** ensure `.kora-agent/` docs+examples are cloned · **R1** read this sub-skill before writing code · **R2** Kora APIs only — no Spring/Micronaut/Quarkus, no invented annotations or config keys · **R3** journal any incorrect Kora usage. Add comments/Javadoc only if asked. MapStruct generates the mapper implementation at compile time. Kora's MapStruct extension detects every `@Mapper` interface, finds the generated `*MapperImpl`, and registers it as a singleton component in the DI graph. You inject the mapper interface by constructor like any other component — **no `@Module` to plug in and no `@Component` on the mapper**. All Kora artifacts inherit their version from the `kora-parent` BOM (`ru.tinkoff.kora:kora-parent:1.2.19` in the example repo) — never version individual `ru.tinkoff.kora:*` dependencies. MapStruct artifacts are versioned explicitly (`1.5.5.Final`). ## Quick Start (Java) `build.gradle`: ```groovy dependencies { koraBom platform("ru.tinkoff.kora:kora-parent:1.2.19") // Kora annotation processor (mandatory) annotationProcessor "ru.tinkoff.kora:annotation-processors" // MapStruct processor — generates the *MapperImpl classes annotationProcessor "org.mapstruct:mapstruct-processor:1.5.5.Final" // MapStruct runtime implementation "org.mapstruct:mapstruct:1.5.5.Final" } ``` `PetMapper.java`
