Java 我在一个JpaQuery spring引导中得到一个空异常

java spring hibernate spring-boot

Java 我在一个JpaQuery spring引导中得到一个空异常,java,spring,hibernate,spring-boot,spring-data-jpa,Java,Spring,Hibernate,Spring Boot,Spring Data Jpa,我将JpaRepository、Hibernate和spring boot与nativeQuery一起用于我的项目，在执行我的查询时，我得到了一个非常奇怪的空值，下面是代码：首先是我的存储库代码（这是返回null的代码）：我的调试返回=检查：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);

我将JpaRepository、Hibernate和spring boot与nativeQuery一起用于我的项目，在执行我的查询时，我得到了一个非常奇怪的空值，下面是代码：

首先是我的存储库代码（这是返回null的代码）：

我的调试返回=

检查：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

在repository类中尝试以下操作：

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

可选选项，您可以使用命名查询（不使用nativeQuery）

要使其工作，必须重命名实体类中的变量，因为它包含下划线

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

参考链接：

这就成功了，谢谢，你知道为什么它是这样工作的吗？你在where子句中使用了一个spel表达式，但根据文档，到目前为止，它似乎只支持entityName（我发布的链接中的第2.3.6节）。
