问题描述

我在Apache Tomcat5.5上使用Spring 2.0.6和Hibernate 3.2.x，现在我们计划将我们的hybernate映射文件改为hybernate + jpa支持映射文件。
为我们创建了这样的文件



daoConfig.xml

在我的daoconfig.xml中，我给出了persistence.xml
的路径，这是我的持久性.xml文件

给我任何建议

解决方案

首先，你是肌酸g Hibernate SessionFactory和JPA EntityManagerFactory。除非你有非常奇怪的设置，否则这没什么意义，你应该很可能抛出SessionFactory配置。您可以配置简单的vanilla Hibernate，或者您可以配置JPA，您不需要两者。



创建实体管理器工厂失败，因为您指定了 JTA 作为事务类型，但未定义JTA事务管理器查找类。 （你在Hibernate的SessionFactory配置文件中定义了它，但不是在你的JPA配置文件中定义它。）

把它添加到你的 persistence.xml中 

 < persistence-unit name =payhubtransaction-type =JTA> 
 
 ... 
 
<属性> 
< property name =hibernate.transaction.manager_lookup_class
 value =com.atomikos.icatch.jta.hibernate3.TransactionManagerLookup/> 
< / properties> 
< / persistence-unit>


I am using Spring 2.0.6 and Hibernate 3.2.x on apache tomcat5.5,now we planed to changed our hybernate mapping files into hybernate+jpa support mapping files. for that we created files like this

daoConfig.xml

in my daoconfig.xml i given path for persistence.xml and this is my persistence.xml file

give me any suggestions

解决方案

First of all, you're creating both a Hibernate SessionFactory and a JPA EntityManagerFactory. That does not make very much sense unless you have a very odd setup, and you should very likely throw out the SessionFactory configuration. You can either configure plain vanilla Hibernate, or you can configure JPA, you don't need both.

The creation of the entity manager factory fails because you specified JTA as the transaction type, but the JTA transaction manager lookup class is not defined. (You defined it in the Hibernate SessionFactory config, but not in your JPA config.)

Add this to your persistence.xml:

<persistence-unit name="payhub" transaction-type="JTA">

    ...

    <properties>
        <property name="hibernate.transaction.manager_lookup_class" 
            value="com.atomikos.icatch.jta.hibernate3.TransactionManagerLookup"/>
    </properties>               
</persistence-unit>

这篇关于所选的事务策略需要访问JTA TransactionManager或无法构建EntityManagerFactory的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
