我正在按照教程在我的项目上实现休眠，虽然我已经在我的配置文件中设置了方言，但它遇到了以下错误。

我的 hibernate.cfg.xml 在 Web-inf > classes

预先添加hibernate.所有属性名称。

<session-factory>

    <!-- Database connection settings -->
    <property name="hibernate.connection.driver_class">
        com.mysql.jdbc.Driver
    </property>
    <property name="hibernate.connection.url">
        jdbc:mysql://localhost:3306/Project1
    </property>
    <property name="hibernate.connection.username">root</property>
    <property name="hibernate.connection.password"></property>

    <!-- JDBC connection pool (use the built-in) -->
    <property name="hibernate.connection.pool_size">1</property>

    <!-- SQL dialect -->
    <property name="hibernate.dialect">
        org.hibernate.dialect.MySQLDialect
    </property>

    <!-- Enable Hibernate's automatic session context management -->
    <property name="hibernate.current_session_context_class">thread</property>

    <!-- Disable the second-level cache  -->
    <property name="hibernate.cache.provider_class">
        org.hibernate.cache.NoCacheProvider
    </property>

    <!-- Echo all executed SQL to stdout -->
    <property name="hibernate.show_sql">true</property>

    <!-- Drop and re-create the database schema on startup -->
    <property name="hibernate.hbm2ddl.auto">update</property>

            <mapping class="com.project.class1" />
            <mapping class="com.project.class2" />

</session-factory>

检查您的类路径中是否有hibernate.cfg.xml文件。并进行以下代码更改。configure()打电话前必须打电话buildSessionFactory()。

static {
    try {

        sessionFactory = new AnnotationConfiguration().configure().buildSessionFactory();
    } catch (Throwable ex) {
        // Log exception!
        throw new ExceptionInInitializerError(ex);
    }
}
