Estoy escribiendo un ejemplo para los datos de primavera. Este es mi spring.xml

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="
    http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd
    http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
    http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd">

<context:component-scan base-package="com.currencyconverter.entity" />

<bean
    class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="location" value="database.properties" />
</bean>

<bean id="dataSource"
    class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="driverClassName" value="${driver.name}" />
    <property name="url" value="${database.url}" />
    <property name="username" value="${database.username}" />
    <property name="password" value="${database.password}" />
</bean>

<bean id="currencyRateImpl" class="com.currencyconverter.dao.CurrencyRateImpl">
    <property name="dataSource" ref="dataSource" />
</bean>


<bean id="entityManagerFactory"
    class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="packagesToScan" value="com.currencyconverter.entity" />
    <property name="jpaVendorAdapter">
        <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" />
    </property>
    <property name="jpaProperties">
        <props>
            <prop key="hibernate.hbm2ddl.auto">create-drop</prop>
            <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>
        </props>
    </property>
</bean>
<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
    <property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>

Y estas son dependencias en mi pom.xml

<dependencies>
    <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>3.8.1</version>

    <dependency>

    </dependency>
</dependencies>

No he usado persistence.xml. Estoy recibiendo la siguiente excepción

Causado por: java.lang.NoSuchMethodError: javax.persistence.spi.PersistenceUnitInfo.getValidationMode () Ljavax / persistence / ValidationMode; en org.hibernate.jpa.boot.internal.PersistenceUnitInfoDescriptor.getValidationMode (PersistenceUnitInfoDescriptor.java:99) en org.hibernate.jpa.boot.internal.EntityManagerFactoryBuilderImpl.mergePropertySources (EntityManagerIa.pa.boot.org. .internal.EntityManagerFactoryBuilderImpl.

Lo que está mal con el código. Las dependencias y versiones son correctas. O persistance.xml es necesario para la primavera 3.2. Si es así, ¿qué debería contener?
