Question

我在applicationContext.xml文件中发生了真正的冲突。

我正在关注本教程集。 Here

在那里我尝试使用MySQL作为数据库。

所以这是我的applicationContext.xml文件。

    </bean>

    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
        destroy-method="close">
        <property name="driverClassName" value="com.mysql.jdbc.Driver" />
        <property name="url" value="jdbc:mysql://localhost:3306/test" />
        <property name="username" value="root" />
    </bean>

    <mvc:annotation-driven />

    <jpa:repositories base-package="com.nought.repository"></jpa:repositories>


    <bean id="sessionFactory"
        class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.hbm2ddl.auto">create</prop>
                <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
            </props>
        </property>
    </bean>

</beans>

我也有4个实体类。

然后我创建扩展JpaRepository。

的存储库类

我的问题是如何使用这些类连接到数据库？我是否要添加另一个声明“SessionFactory”的类？

在applicationContext.xml中想要做哪些更改？

有人能帮我吗？

这是完整的applicationContext.xml文件。

希望这会对其他人有所帮助.....

使用sessionFactory bean配置applicationContext.xml时发生冲突
