当我搜索这个问题时,有人说我们应该使用springframework.orm.hibernate4而不是springframework.orm.hibernate3.我做到了 但我仍然得到同样的例外.

有人可以帮我识别我在这里缺少的东西.

谢谢

Answer 1

注意:在从Hibernate 3到Hibernate 4的更改中删除了org.hibernate.cache.Provider.

如果你使用hibernate 3,你可能会得到java.lang.ClassNotFoundException: org.hibernate.cache.CacheProvider.如果你改为休眠4,你就不会那样,但你首先应该添加hibernate4.jar和spring-orm.jar.

Answer 2

听起来您在项目设置中缺少 hibernate 依赖项：

引起原因：java.lang.ClassNotFoundException：org.hibernate.cache.CacheProvider

尝试下载hibernate-core.jar并将其添加到您的项目类路径中。

如果您使用 Maven，只需将以下依赖项添加到项目的 pom.xml 中：

<dependency>
  <groupId>org.hibernate</groupId>
  <artifactId>hibernate-core</artifactId>
  <version>${hibernate.version}</version>
</dependency>

希望有帮助。
