Question

我正在尝试使用mysql配置hibernate。

以下是hibernate.cfg.xml：

<hibernate-configuration>
    <session-factory>    
        <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/TestDB</property>
        <property name="hibernate.connection.username">root</property>
        <property name="hibernate.connection.password">root123</property>
        <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>


        <property name="hdm2ddl.auto">create</property>property>
        <property name="show_sql">false</property>


        <!-- Use the C3P0 connection pool provider -->
        <property name="hibernate.c3p0.min_size">5</property>
        <property name="hibernate.c3p0.max_size">20</property>
        <property name="hibernate.c3p0.timeout">300</property>
        <property name="hibernate.c3p0.max_statements">50</property>
        <property name="hibernate.c3p0.idle_test_period">3000</property>

        <mapping resource="com/psl/course/Course.hbm.xml"/>

    </session-factory>
</hibernate-configuration>

但是，我遇到了以下错误。堆栈跟踪如下，

请帮助，我哪里出错？

Answer 1

您在XML中输错：

<property name="hdm2ddl.auto">create</property>property>

Answer 2

会话工厂的定义顺序必须遵循异常中的hte顺序

属性*，映射*，（类缓存|收集高速缓冲存储器）的，事件，听者*

我猜测发布的cfg.xml文件不是整个文件。（原始文件中的第26行）

使用mysql进行Hibernate配置会产生ERROR - SAXParseException
