我想用JPA和Spring連接到MySQL數據庫。我對Spring很陌生。此外JPA Spring MVC配置
<jee:jndi-lookup id="myEmf" jndi-name="hello-world"/>
<bean id="myEmf" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="myEmf"/>
<property name="loadTimeWeaver">
<bean class="org.springframework.instrument.classloading.InstrumentationLoadTimeWeaver"/>
</property>
</bean>
這裏是我的persistence.xml，我的持久性單元名稱是「你好，世界」：
我已經加入這個我的配置文件，所有的豆類定義。
<persistence-unit name="hello-world" transaction-type="RESOURCE_LOCAL">
org.hibernate.ejb.HibernatePersistence
當我嘗試實例化對象，它引發了我的錯誤。
謝謝， 莎拉。
更新，錯誤：
