我正在使用 spring、jpa 和 hibernate 创建一些项目。这是我的spring配置（我真的不知道我的配置是否正确）。我也在使用 Maven 添加依赖项
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location" value="classpath:database.properties">
<value>classpath:database.properties</value>
</property>
</bean>
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="${hibernate.connection.driver_class}"/>
<property name="url" value="${hibernate.connection.url}"/>
<property name="username" value="${hibernate.connection.username}"/>
<property name="password" value="${hibernate.connection.password}"/>
</bean>
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="persistenceUnitName" value="RAM"/>
<property name="persistenceXmlLocation" value="classpath:META-INF/persistence.xml"/>
<property name="jpaVendorAdapter">
</bean>
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<property name="showSql" value="${hibernate.show_sql}"/>
<property name="databasePlatform" value="org.springframework.orm.jpa.vendor.HibernateJpaDialect"/>
<property name="generateDdl" value="false"/>
</property>
<property name="jpaDialect">
<bean class="${jpa.dialect}"/>
</property>
</bean>
<bean id="txManager" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory"/>
</bean>
这是我遇到的错误的打印堆栈跟踪：
