未找到hibernate maven項目中的mysql類

我在eclipse Helios中創建了一個maven項目，並在pom.xml依賴關係中添加了「hibernate-search 4.0.0.Final」和「mysql-connector-java 5.1.18」。都下載並存在.m2目錄中。但是當我運行這段代碼：未找到hibernate maven項目中的mysql類

Session session = HibernateUtil.getSessionFactory().openSession(); 
session.beginTransaction(); 
session.getTransaction().commit();

只是在數據庫中創建表在表中導入以前提供的值，我得到以下錯誤：

我不知道該怎麼辦？我GOOGLE了這個錯誤，但沒有成功。 PLZ幫助我。提前致謝。

它看起來像某事（或某人）已將JDBC URL放在一個屬性中，該屬性假定包含類名稱。

Caused by: java.lang.ClassNotFoundException: 
    Could not load requested class : 
    jdbc:mysql://localhost:3306/test?createDatabaseIfNotExist=true&useUnicode=true&characterEncoding=utf-8

這不是類名，而應該是。

檢查配置屬性...

在Hibernate配置文件中，指定數據庫的URL，其中休眠搜索數據庫的話：

Dialect class not found: jdbc:mysql://localhost:3306/test?createDatabaseIfNotExist=true&useUnicode=true&characterEncoding=utf-8

的話必須是類（例如，org.hibernate.dialect.MySQL5Dialect）。

請參閱http://docs.jboss.org/hibernate/core/3.6/reference/en-US/html_single/#tutorial-firstapp-configuration
