Spring Data JPA @Query 注释将查询作为字符串而不是查询

Question

我有这个扩展 JPA 存储库的存储库。接口中定义的方法(findBySearchQuery)实现了Spring Data JPA的@Query注释。注释内的查询被视为字符串，但不被视为查询。

package com.QuickBite.QuickBite.repository;

import com.QuickBite.QuickBite.model.Restaurant;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Query;
import org.springframework.stereotype.Repository;

import java.util.List;

@Repository
public interface RestaurantRepository extends JpaRepository<Restaurant, Long> {

    @Query("SELECT r FROM RESTAURANT r WHERE lower(r.name) LIKE lower(concat('%', :query, '%')) " +
            "OR lower(r.cuisineType) LIKE lower(concat('%', :query, '%'))" )
    List<Restaurant> findBySearchQuery(String query);

    Restaurant findByOwnerId(Long userId);
}

服务文件

package com.QuickBite.QuickBite.Service;

import com.QuickBite.QuickBite.model.Restaurant;

import java.util.List;

public interface RestaurantService {

    public List<Restaurant> searchRestaurant(String keyword);


}

包含 findBySearchQuery 方法的服务实现文件

package com.QuickBite.QuickBite.Service;

import com.QuickBite.QuickBite.model.Restaurant;
import com.QuickBite.QuickBite.repository.RestaurantRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

@Service
public class RestaurantServiceImp implements RestaurantService{

    @Autowired
    private RestaurantRepository restaurantRepository;


    @Override
    public List<Restaurant> searchRestaurant(String keyword) {
        return restaurantRepository.findBySearchQuery(keyword);
    }

}

我低于所有例外。

Answer 1

您使用的是 JPQL 还是普通 SQL？ 如果是 JPQL，我假设 Restaurant 是您的班级名称。

package com.QuickBite.QuickBite.repository;

import com.QuickBite.QuickBite.model.Restaurant;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Query;
import org.springframework.stereotype.Repository;

import java.util.List;

@Repository
public interface RestaurantRepository extends JpaRepository<Restaurant, Long> {

    @Query("SELECT r FROM Restaurant r WHERE lower(r.name) LIKE lower(concat('%', :query, '%')) " +
            "OR lower(r.cuisineType) LIKE lower(concat('%', :query, '%'))" )
    List<Restaurant> findBySearchQuery(String query);

    Restaurant findByOwnerId(Long userId);
}

如果是普通sql那么你需要设置nativeQuery=true

package com.QuickBite.QuickBite.repository;

import com.QuickBite.QuickBite.model.Restaurant;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Query;
import org.springframework.stereotype.Repository;

import java.util.List;

@Repository
public interface RestaurantRepository extends JpaRepository<Restaurant, Long> {

    @Query("SELECT r FROM RESTAURANT r WHERE lower(r.name) LIKE lower(concat('%', :query, '%')) " +
            "OR lower(r.cuisineType) LIKE lower(concat('%', :query, '%'))" , nativeQuery = true)
    List<Restaurant> findBySearchQuery(String query);

    Restaurant findByOwnerId(Long userId);
}
