java - org.hibernate.MappingException : An AnnotationConfiguration instance is required to use

Question

我正在使用 HIbernate core 3.6.2 Final。我将注释类映射放在 hibernate.cfg.xml 中，例如

由于我使用 Hibernate 版本 3.6.2，我不需要创建注释配置类对象。所以我创建配置对象为私有(private)静态最终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;
}

但是给了我错误初始 SessionFactory 创建失败.org.hibernate.MappingException:需要 AnnotationConfiguration 实例才能使用org.hibernate.MappingException:需要 AnnotationConfiguration 实例才能使用

我的波姆。 xml 是作为http://maven.apache.org/maven-v4_0_0.xsd"> 4.0.0 tdm 网站 时分复用 war 0.0.1-快照 tdm Maven Web 应用程序 奥 git _a 朱尼特 朱尼特 3.8.1 测试

Answer 1

Hibernate 3.6.2 不会生成此类异常

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

有hibernate-core在类路径中添加 3.6.0 版本之前的 jar。例如hibernate-core-3.5.0-Final.jar .

请检查像 hibernate3.jar 这样的 jar 在 lib您的 war 的文件夹或默认 lib Glassfish 应用程序服务器的文件夹 ( #glassfish_home#/lib )。
