java - Spring hibernate 异常

Question

当我启动 SpringMVC 时，出现以下异常...

重要的细节似乎在错误中:org.hibernate.tool.hbm2ddl.SchemaUpdate - 无法获取数据库元数据

我的servlet-context.xml如下...

我确定数据库的 url 详细信息和凭据是正确的，有人能想到任何其他原因吗？

看起来它正在尝试访问 information_schema 数据库，但在我的 XML 中我已经设置了它应该查看的数据库...

<beans:bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
        destroy-method="close">
        <beans:property name="driverClassName" value="com.mysql.jdbc.Driver" />
        <beans:property name="url" value="jdbc:mysql://localhost/assessme" />
        <beans:property name="username" value="root" />
        <beans:property name="password" value="toor" />
    </beans:bean>

谢谢，

Answer 1

我正在从不同答案的评论中提取此问题的正确答案。

抛出此异常是因为您使用的方言与数据库不匹配。

在你的配置中你使用

<beans:prop key="hibernate.dialect">org.hibernate.dialect.H2Dialect</beans:prop>

尽管您正在访问 MySQL 数据库。您应该改用 MySQL 方言。例如

<beans:prop key="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</beans:prop>
