如何使用entitymanager修复persistence.xml和applicationContext.xml？

Question

我使用hibernate，我想要基本的crud，但我没有配置persistence.xml和applicationContext.xml配置文件。我想使用EntityManager而不是Session。

这是我的applicationContext.xml

<context:annotation-config />

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

    <tx:annotation-driven />
    <bean class = "org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor" />

    <bean id="dataSource"
          class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="com.mysql.jdbc.Driver" />
        <property name="url" value="jdbc:mysql://localhost:3307/toyotadb" />
        <property name="username" value="root" />
        <property name="password" value="12345" />
    </bean>



     <bean id="entityManagerFactory"
            class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
            <context:component-scan base-package="com.toyotaproject.domain" />
            <property name="persistenceXmlLocation" value="SpringJPA_PU"></property>
            <property name="dataSource" ref="dataSource" />
            <property name="jpaVendorAdapter" ref="jpaAdapter" />
            <property name="loadTimeWeaver">
                <bean
                        class="org.springframework.instrument.classloading.InstrumentationLoadTimeWeaver" />
            </property>
        </bean>

        <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
            <property name="entityManagerFactory" ref="entityManagerFactory" />
        </bean>

        <bean id="jpaAdapter"
              class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
            <property name="database" value="MYSQL" />
            <property name="showSql" value="true" />
            <property name="generateDdl" value="true" />
        </bean>

    </beans>

    this is my persistence.xml.

<?xml version="1.0" encoding="UTF-8"?>

            <!-- property name="eclipselink.logging.level" value="OFF" /-->

        </properties>

    </persistence-unit>


</persistence>

我在哪里做错了？
