如何在Spring Boot应用程序中使用MapStruct映射2个对象？

<dependency>
    <groupId>org.mapstruct</groupId>
    <artifactId>mapstruct</artifactId>
    <version>1.4.2.Final</version>
</dependency>

public class Source {
    private String name;
    private int age;
    // getters and setters
}

public class Target {
    private String fullName;
    private int years;
    // getters and setters
}

@Mapper
public interface MyMapper {
    MyMapper INSTANCE = Mappers.getMapper(MyMapper.class);

    @Mapping(source = "name", target = "fullName")
    @Mapping(source = "age", target = "years")
    Target sourceToTarget(Source source);

    @InheritInverseConfiguration
    Source targetToSource(Target target);
}

@RestController
public class MyController {
    @Autowired
    private MyMapper mapper;

    @PostMapping("/map")
    public Target mapObjects(@RequestBody Source source) {
        return mapper.sourceToTarget(source);
    }
}
