Question

私はspring-data-jpaおよびネイティブクエリの新機能です。この例では、私は（結果を示す）は、次のSQLは、クエリの結果とJPAリポジトリクエリ

select c.* from customers c INNER JOIN orders o ON c.customerNumber=o.customerNumber where c.city='Nantes'; 

enter image description here

画像に変換したい：だから

、私は以下のようにしました -

CustomerRepository.java

public interface CustomerRepository extends JpaRepository<Customer, Long>{ 
    List<Customer> findByContactFirstName(String firstName); 

    @Query("select c from Customer c INNER JOIN Order o ON c.customerNumber=o.customerNumber where c.city=:city") 
    List<Customer> findByCustomerNumberByCity(@Param("city") String city); 
} 

私はテストクラスで

@Test 
    public void testByCustomerNumber(){ 
     List<Customer> customers = customerRepository.findByCustomerNumberByCity("Nantes"); 
     System.out.println("Size of Customers : "+customers.size()); 
    } 

これを実行しています、私は以下のエラーが来る参照してください。

Answer 1

私は問題を参照してください。 JPA @Queryを正しい方法でリファクタリングする必要があります。以下は正常に動作します。

@Query("SELECT c FROM Customer c JOIN c.orders o WHERE c.customerNumber = 
o.customer.customerNumber AND c.city=:city") 
List<Customer> findByCustomerNumberByCity(@Param("city") String city); 

あなたがリンクからMySQLのスキーマを使用しています：強調表示の部分に答えるために

@Test 
public void testfindByCustomerNumberByCityJPA(){ 
    List<Customer> customers = custmerRepository.findByCustomerNumberByCity("Nantes"); 
    System.out.println("Size of Customers : "+customers.size()); 
} 

：http://www.mysqltutorial.org/mysql-sample-database.aspx .IFをはい次のテストケースは結果をもたらす

1）JPA repositoryクエリはしませんあなたが複雑な結合作業をしているなら、良い選択肢になります。あなたが結合のカップルをしている場合JPA repositoryクエリは良いオプションです。

2）あなたは、複雑で作業している場合は、SQLネイティブクエリされる場所、そのことをお勧めEntityManagerを使用して、このQuery query = em.createNativeQuery(sql.toString());のようなネイティブクエリを作成するには、多くのテーブルを結合します。
