Failed to determine Hibernate PersistenceProvider
提问by bkowalczyyk
I am trying to configure LocalContainerEntityManagerFactoryBean without persisten.xml file.
我正在尝试在没有 persisten.xml 文件的情况下配置 LocalContainerEntityManagerFactoryBean。
this is my dataSource - it works for Hibernate SessionFactory - so, it is ok.
这是我的数据源 - 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>
this is my LocalContainerEntityManagerFactoryBean
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>
An exception that i am getting:
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
I read documentation, and i know that LocalContainerEntityManagerFactoryBean has such property, and similar style of creating LocalContainerEntityManagerFactoryBean works in Spring in Action 3 and here: http://softwarecave.org/2014/03/15/using-jpa-and-jta-with-spring/
我阅读了文档，我知道 LocalContainerEntityManagerFactoryBean 具有这样的属性，并且创建 LocalContainerEntityManagerFactoryBean 的类似风格在 Spring in Action 3 和这里工作：http: //softwarecave.org/2014/03/15/using-jpa-and-jta-带弹簧/
Maybe You have an idea what i am doing wrong or at least what spring want tell me via this exception ?
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？
Thanks in advance, Cheers :)
提前致谢，干杯:)
P.S to be clear, Failed to determine Hibernate PersistenceProvider doesn't mean that spring expect persistence.xml - this should be error like: No persistence units parsed from {classpath*:META-INF/persistence.xml}
PS要明确，无法确定Hibernate PersistenceProvider并不意味着spring期望persistence.xml - 这应该是错误，例如：Nopersistence unit parsed from {classpath*:META-INF/persistence.xml}
RESOLVED:
解决：
thanks JB Nizet - if You will have similar problem add:

Below code works for me.
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>
With hibernate = 4.3.5.Final spring=4.1.4.RELEASE
随着休眠 = 4.3.5.Final spring=4.1.4.RELEASE
