“未找到名称为'product'的持久性单元” [英] "No persistence unit with name 'product' found"

问题描述

我最近完成了本教程： http：// static。 springource.org/docs/Spring-MVC-step-by-step/ ，但现在我希望它能够与Hibernate和注释一起工作。我知道我很接近，但我遇到了障碍，我无法弄清楚。我已将自己的代码发布到Spring论坛此处 。我非常感谢任何帮助。谢谢

我试图将注释和hibernate合并到它中，但是我遇到了一个问题，我无法弄清楚。我不断收到没有找到名称为'product'的持久性单元的错误。你需要一个 META-INF / persistence.xml

code>，其中< persistence-unit name =product> 。 请看这里

（我通常把它放在 WEB-INF / classes / META-INF 中。 maven你可以把它放在 src / main / resources / META-INF ）

I recently completed this tutorial: "http://static.springsource.org/docs/Spring-MVC-step-by-step/", but now I want it to work with Hibernate and annotations. I know I'm close but I've hit a roadblock and I can't figure it out. I've posted my code on the Spring forums here. I would greatly appreciate ANY help. Thanks

I'm trying to incorporate annotations and hibernate into it, but I've run into a problem and I can't figure it out. I keep getting errors of "No persistence unit with name 'product' found". ANY help would be greatly appreciated.

解决方案

You need a META-INF/persistence.xml, with <persistence-unit name="product">. See here

(I usually put it in WEB-INF/classes/META-INF. As noted in the comments, with maven you can place it in src/main/resources/META-INF)
