【问题描述】：

我正在使用 HIbernate core 3.6.2 final。我把注解类映射在hibernate.cfg.xml比如

而且由于我使用的是 3.6.2 的 Hibernate 版本，因此我不需要创建注释配置类对象。所以我创建配置对象为 private static final SessionFactory sessionFactory;

static {
    try {

        sessionFactory = new Configuration().configure("hibernate.cfg.xml").buildSessionFactory();
    } catch (Throwable ex) {
        // Log the exception.
        System.err.println("Initial SessionFactory creation failed." + ex);
        throw new ExceptionInInitializerError(ex);
    }
}

public static SessionFactory getSessionFactory() {
    return sessionFactory;
}

但是给了我错误 Initial SessionFactory creation failed.org.hibernate.MappingException: AnnotationConfiguration 实例需要使用 org.hibernate.MappingException: AnnotationConfiguration 实例需要使用

【问题讨论】：

关心“hibernate.cfg.xml”中的内容吗？

标签： java hibernate jersey nhibernate-mapping

【解决方案1】：

Hibernate 3.6.2 不会产生此类异常

org.hibernate.MappingException: An AnnotationConfiguration instance is required to use <mapping class="entities.Employee"/>

在你的类路径中有hibernate-core jar 早于 3.6.0 版本。例如hibernate-core-3.5.0-Final.jar。

请在您的 war 的 lib 文件夹或 Glassfish 应用服务器的默认 lib文件夹 (#glassfish_home#/lib) 中检查像 hibernate3.jar 这样的 jar。

【讨论】：

我正在使用 maven 项目。我在 pom.xml 中添加所有依赖项。我添加了这个依赖 org.hibernatehibernate-core3.6.2.Final 但同样的错误。如果我更改 Java 版本 1.7，则说明资源无法将项目方面动态 Web 模块的版本更改为 3.0。 tdmserver
@Harshit 你的pom.xml 是正确的。我认为，当您部署应用程序时（例如来自默认 glassfish 的 lib 文件夹），类似 hibernate3.jar 的内容会出现在您的类路径中。
@v.ladynev 我正在使用 Tomcat 服务器。我没有使用 glassfish 服务器。
