Question

所以我的项目中有这个pom.xml，想生成一个QHotel类。

            </plugin>
        </plugins>
    </build>

</project>

我的存储库界面是

@Repository
public interface HotelRepository extends MongoRepository<Hotel, String>, QuerydslPredicateExecutor<Hotel> {

    Optional<Hotel> findHotelById(String id);

    List<Hotel> findByPricePerNightLessThan(int max);

    @Query(value = "{'address.city':?0}")
    List<Hotel> findByCity(String city);
}

但是当我输入终端 mvn clean install

我回来了

Caused by: java.lang.IllegalArgumentException: Did not find a query class theo.hotels.demo.model.QHotel for domain class theo.hotels.demo.model.Hotel!

我尝试了this解决方案，但还是没有。
