Question

我在我的项目中使用JpaRepository，Hibernate和spring-boot并带有nativeQuery，在执行查询时我得到了一个非常奇怪的null值，这是代码：

首先是我的存储库代码（这是返回null的代码）：

public interface PaquetesRepository extends JpaRepository<Paquetes, Integer>{

    @Query(value = "SELECT * FROM paquetes WHERE tipousuario_id = ?#{#tipoUser}", nativeQuery = true)
    Paquetes getPaqueteDelUsuario(int tipoUser);

}

以下图片显示它确实有数据：

第二个我的服务代码：

@Override
    public Paquetes getPaqueteDelUsuario(int tipoUser) {
        System.out.println("Check: " + paquetesRepository.getPaqueteDelUsuario(tipoUser) + " , " + tipoUser);
        return paquetesRepository.getPaqueteDelUsuario(tipoUser);
    }

我的调试返回= Check: null , 2

在我的控制器中，我这样称呼它：

Paquetes paquete = paqueteService.getPaqueteDelUsuario(tipo);
System.out.println("Paquete: " + paquete);

println返回= Paquete: null

还有我的Application.properties：

这是我的StackTrace：

在存储库类中尝试一下：

@Query(
  value = "SELECT * FROM paquetes WHERE tipousuario_id = ?1", 
  nativeQuery = true)
Paquetes getPaqueteDelUsuario(Integer tipoUser);

替代选项，您可以使用命名查询（不使用nativeQuery）

paquetesRepository.getPaqueteDelUsuarioByTipousuarioId(tipoUser);

为此，您必须在Entity类中重命名该变量，因为该变量包含下划线。

@Column(name = "tipousuario_id", nullable = false)
private Integer tipousuarioId;
