JDBC Driver類

Question

我有與Hibernate的配置有問題，當我運行的類測試affich：

JDBC Driver class not found: com.jdbc.mysql.driver 
3 mai 2011 09:47:52 net.sf.hibernate.connection.DriverManagerConnectionProvider configure 
GRAVE: JDBC Driver class not found: com.jdbc.mysql.driver 

Answer 1

你在你的classpath需要mysql-connector-*.jar

Answer 2

嘗試使用這些屬性值：

<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property> 
... 
<property name="hibernate.query.factory_class">org.hibernate.hql.classic.ClassicQueryTranslatorFactory</property> 

檢查hibernate3.jar是否也在您的路徑中。

Answer 3

JDBC Driver class not found: com.jdbc.mysql.driver

全限定類名是區分大小寫的。您需要在您的Hibernate配置文件中聲明com.mysql.jdbc.Driver大寫D，而不是com.mysql.jdbc.driver小寫d。
