Spring Data Rest 执行查询但是 returns 500 内部服务器错误
Spring Data Rest executes query but returns 500 internal Server Error
我正在使用 spring 引导和 spring 数据休息，我面临 500 内部服务器错误，但控制台中没有显示任何消息。
我有以下内容：
ProdutoVendaRepository.java
public interface ProdutoVendaRepository extends PagingAndSortingRepository<ProdutoVenda, Integer> {
@Query("SELECT new br.com.contoso.model.VendaPorFamilia(b.nome, SUM(i.valorMultiplicado)) FROM ProdutoVenda i JOIN i.produto o JOIN o.familia b WHERE b.nome LIKE 'foo' GROUP BY b.nome")
List <VendaPorFamilia> teste();
}
VendaPorFamilia.java
public class VendaPorFamilia {
private String nome;
private double valorTotal;
public VendaPorFamilia(String nome, double valorTotal) {
this.nome = nome;
this.valorTotal = valorTotal;
}
//getters and setters
ProdutoVenda.java
@Entity
@Immutable
@Table(name = "INV1")
public class ProdutoVenda {
@Id
@Column(name = "LineNum")
private int id;
@Column(name = "ItemCode")
private String codigo;
@Column(name = "Quantity")
private double quantidade;
@Column(name = "Price")
private double precoUnitario;
@Column(name = "LineTotal")
private double valorMultiplicado;
@Column(name = "Dscription")
private String descricao;
@OneToOne
@JoinColumn(name = "ItemCode", updatable = false, insertable = false)
private Produto produto;
//getters and setters
当我尝试
curl -v -X GET -H "X-AUTH-TOKEN: TokenFoo"
http://localhost:8080/api/produtoVendas/search/teste
日志显示执行了查询：
2015-06-16 17:05:45.884 DEBUG 7892 --- [http-nio-8080-exec-1] org.hibernate.SQL
: select familia2_.ItmsGrpNam as col_0_0_, sum(produtoven0_.LineTotal) as col_1_0_ from
INV1 produtoven0_ inner join OITM produto1_ on produtoven0_.ItemCode=produto1_.ItemCode
inner join OITB familia2_ on produto1_.ItmsGrpCod=familia2_.ItmsGrpCod where
familia2_.ItmsGrpNam like 'foo' group by familia2_.ItmsGrpNam
但我收到：
< HTTP/1.1 500 Internal Server Error
* Server Apache-Coyote/1.1 is not blacklisted
< Server: Apache-Coyote/1.1
< Content-Length: 0
< Date: Tue, 16 Jun 2015 20:05:46 GMT
< Connection: close

* Closing connection 0
我不知道该怎么做，我尝试了很多方法，但似乎没有任何效果。
是的，当我在 MsSQL 服务器中执行完全相同的生成查询时，它 returns 想要的值。
所有其他存储库都可以正常工作...
感谢您的宝贵时间和帮助！

在与数据库建立连接的线路上放置一个调试器。
嗯……
这很奇怪，但我发现了这个 question 并添加了一个控制器来调用该方法，它非常有效...
显然这不是修复，但它是一个很好的解决方法...
编辑：错误发生是因为它期待一个实体，所以我所要做的就是用@Entity 注释 VendaPorFamilia。
