如何在父对象上使用mapstruct来检测正确的子映射器？

public class Parent {
    private Child child;
    // 其他父对象属性和方法
}

public class Child {
    private String name;
    // 其他子对象属性和方法
}

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

    @Mappings({
        @Mapping(source = "name", target = "name")
        // 其他子对象字段映射规则
    })
    ChildDto toDto(Child child);
}

@Mapper(uses = ChildMapper.class)
public interface ParentMapper {
    ParentMapper INSTANCE = Mappers.getMapper(ParentMapper.class);

    ParentDto toDto(Parent parent);
}

Parent parent = new Parent();
Child child = new Child();
child.setName("John Doe");
parent.setChild(child);

ParentDto parentDto = ParentMapper.INSTANCE.toDto(parent);
