我正在开发 Spring JPA QueryDSL 示例。我只是在遵循 link 中的示例：https://github.com/eugenp/tutorials/tree/master/querydsl，这对我来说是一个很好的教程。当我编译这个项目时，它编译成功。但是当尝试执行测试用例时，我看到以下错误。

我试图重现这个错误，但我也看到了同样的问题。由于您正在使用 Java 8，因此您需要更新 spring framework version to 4.x.x（因为 java 8 需要 spring 4.x）。 您还需要使用以下构建插件才能将 QPerson class 添加到您的 DAOImpl class。希望这会有所帮助。

我试图重现这个错误，但我也看到了同样的问题。由于您正在使用 Java 8，因此您需要更新 spring framework version to 4.x.x（因为 java 8 需要 spring 4.x）。 您还需要使用以下构建插件才能将 QPerson class 添加到您的 DAOImpl class。希望这会有所帮助。
