无法确定Hibernate PersistenceProvider

Question

我试图配置没有persisten.xml文件的LocalContainerEntityManagerFactoryBean.

这是我的dataSource - 它适用于Hibernate SessionFactory - 所以,没关系.

<bean id="dataSource"
    class="org.apache.commons.dbcp2.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"/>
    <property name="password" value="root"/>
</bean>

这是我的LocalContainerEntityManagerFactoryBean

   <bean id="myEmf" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
   <property name="dataSource" ref="dataSource" />
   <property name="packagesToScan" value="application.models" />
   <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.MySQLDialect</prop>
      </props>
   </property>
</bean>

我得到的一个例外:

...Could not instantiate bean class [org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter]: Constructor threw exception; nested exception is java.lang.IllegalStateException: Failed to determine Hibernate PersistenceProvider

我阅读文档,我知道LocalContainerEntityManagerFactoryBean有这样的属性,类似的创建LocalContainerEntityManagerFactoryBean的风格在Spring in Action 3和这里工作:http://softwarecave.org/2014/03/15/using-jpa-and-jta-与弹簧/

也许你知道我做错了什么,或者至少春天想通过这个例外告诉我什么？

在此先感谢,干杯:)

PS要清楚,未能确定Hibernate PersistenceProvider并不意味着spring期望persistence.xml - 这应该是错误的:没有从{classpath*:META-INF/persistence.xml}解析的持久性单元

解决:

感谢JB Nizet - 如果你有类似的问题补充:

    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-entitymanager</artifactId>
        <version>4.3.6.Final</version>
    </dependency>

到pom.xml

下面的代码对我有用。

<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean" p:dataSource-ref="dataSource">
    <property  name="jpaVendorAdapter">
         <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
            <property name="showSql" value="true" />
            <property name="databasePlatform" value="org.hibernate.dialect.MySQLDialect" />
        </bean>
    </property>
</bean>
