我目前已将Spring配置为使用HSQL，但我想使用MySQL。需要改变什么？

    <bean id="myUserDAO" class="uk.co.vinoth.spring.dao.UserDAOImpl">

    </bean>

    <bean name="/user/*.htm" class="uk.co.vinoth.spring.web.UserController" >
        <property name="userDAO" ref="myUserDAO" />
    </bean>

</beans>

Answer 1

更改以下属性：

    <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
    <property name="url" value="jdbc:mysql://127.0.0.1:3306/schema"/>

    <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>

（其中'schema'是你的mysql数据库名称，假设你的mysql主机是127.0.0.1）

将mysql-connector jar添加到类路径中。

Answer 2

您必须更改driverClass的{{1}}和url属性。

DataSource应为driverClass
com.mysql.jdbc.Driver应为url

Answer 3

在mysql website

中详细介绍了在Spring中使用mysql和java的一个很好的例子

冬眠应该在常春藤的答案中注明。

使用Java连接MySQL
