【问题描述】：

我是 Spring 的新手，我遵循从头开始创建项目的教程。我发现 5 篇有类似问题的帖子，但帖子中的解决方案对我没有帮助。我无法在 2 周内解决这个问题，如果有人可以帮助我，我将不胜感激。

【问题讨论】：

将所有 bean 定义从 applicationContext.xml 移动到 dispatcher-servlet.xml。然后尝试评论结果
@Ramanujan R 好的，我试过了，没有成功。
在 ProductDaoImpl 我得到这个错误：prntscr.com/en1brd
Spring 4.3.3 是否支持休眠 5.2.9？将休眠版本更改为 5.2.2.Final 并尝试。弃用警告是由于 org.hibernate.query.Query 在 hibernate >= 5.2.2.Final 中弃用。现在好了。但是session.createQuery("from Product") 是对的。你也可以使用session.createQuery("select p from Product p")
好的，谢谢，我将休眠更改为 5.2.2.Final。问题依然存在。

标签： java spring hibernate maven

【解决方案1】：

org/hibernate/boot/model/naming/ImplicitNamingStrategy，据说是缺失的，肯定是 hibernate-core 库的一部分，您在 pom.xml 中具有该依赖项。

可能导致问题的一件事是包含：

    <dependency>
        <groupId>org.hibernate.javax.persistence</groupId>
        <artifactId>hibernate-jpa-2.0-api</artifactId>
        <version>1.0.1.Final</version>
    </dependency>

因为你的版本 hibernate-core 有这个依赖：

    <dependency>
        <groupId>org.hibernate.javax.persistence</groupId>
        <artifactId>hibernate-jpa-2.1-api</artifactId>
        <version>1.0.0.Final</version>
    </dependency>

由于它们是不同的工件，它们都将包含在包中。

在 2.0 和 2.1 版本中使用 jpa api 可能会导致问题。

【讨论】：

你试过这个解决方案是什么意思？从 pom 中删除了hibernate-jpa-2.0-api？如果不是，请删除该依赖项。
@ Ramanujan R 我的意思是我改变了依赖关系：hibernate-jpa-2.1-ap 和 1.0.0 Final 现在我删除了依赖关系并启动项目问题仍然存在。:(
