使用 Querydsl 创建自定义存储库时遇到错误。(javax.persistence.NoResultException)

问题描述 投票：0回答：1

我相信我已经正确设置了 Spring Boot 版本 3.1.8 的依赖项，如下面的 build.gradle 代码所示。

我正在尝试实现一项功能，将文章中的唯一主题标签列表发送给用户。

为了实现这一目标，我使用 Querydsl 自定义存储库以从 Article 表中获取此数据

我还将此功能添加到服务层和控制器层。我使用 Thymeleaf 将此数据发送给用户，并且还编写了 HTML。

虽然我的所有测试都通过了，但该功能在实际应用程序中不起作用。有人可以帮我找到解决方案吗？

  • 我确认所有存储库都指定了“最终”，但问题仍然存在。

  • 其他 Querydsl 查询（例如 findByContentContaining）运行良好。

  • 我还尝试更改构建和运行设置。

    • [构建并运行：Intellij，运行并取消：Gradle]

经过两天的努力，我终于修复了这个错误。这是我的解决方案，以防其他人遇到同样的问题：

确保检查依赖关系。 我通过更改解决了该错误

implementation "com.querydsl:querydsl-jpa"

到

implementation "com.querydsl:querydsl-jpa:${dependencyManagement.importedProperties['querydsl.version']}:jakarta"

仅指定实现“com.querydsl:querydsl-jpa”时，Querydsl 似乎无法找到 jakarta.persistence.api。

这个调整对我有用。 伙计们，祝您编码愉快！
