Spring 4.0.6 + Weblogic 10.3.6 + EJB 3.0 CMT + Spring Data JPA 1.6.2的事务异常-“错误绑定到外部管理的事务” [英] Transaction Exception with Spring 4.0.6 + Weblogic 10.3.6 + EJB 3.0 CMT + Spring Data JPA 1.6.2 - "Error binding to externally managed transaction"
本文介绍了Spring 4.0.6 + Weblogic 10.3.6 + EJB 3.0 CMT + Spring Data JPA 1.6.2的事务异常-“错误绑定到外部管理的事务”的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
使用Weblogic 10.3.6，Spring 4.0.6，Spring Data JPA 1.6.2，Eclipselink（同时复制了Weblogic嵌入式2.3版本和最新的2.5.2）时，我遇到了一个奇怪且难以调试的问题，并且容器托管交易。
（我将Weblogic更新为使用JPA 2.0安装Oracle提供的补丁）。
I am having a weird, and hard to debug, issue using Weblogic 10.3.6, Spring 4.0.6, Spring Data JPA 1.6.2, Eclipselink (reproduced both the Weblogic embedded 2.3 version and the newest 2.5.2) and Container Managed Transactions. (I updated Weblogic to use JPA 2.0 installing the patch provided by Oracle).
问题如下：我有一个简单的无状态EJB 3.0在其中确实使用了Spring Autowiring和spring-data-jpa存储库。
The issue is the following: I have a simple, stateless, EJB 3.0 in which I do use Spring Autowiring and spring-data-jpa repositories.
当我调用EJB公开的任何服务时，都会得到以下奇怪的异常（请注意，我必须查找/替换所有真实的类名/路径）：
When I do call any service exposed by the EJB, I get the following, weird, exception (please notice that I had to find/replace all the real class names/paths):
EJB Exception: : com.oracle.pitchfork.interfaces.LifecycleCallbackException: Failure to invoke public void org.springframework.ejb.interceptor.SpringBeanAutowiringInterceptor.autowireBean(javax.interceptor.InvocationContext) on bean class class

似乎Spring无法初始化JPA信息库如果无状态Bean的创建是由对Transactional方法的调用触发的！！
it seems that Spring is not able to initialize a JPA repository if the Stateless bean creation is triggered by a call to a Transactional method!!!
实际上，如果我执行以下操作：
1.调用非- ejb上的事务处理方法（@ TransactionAttributeType.NEVER）：此调用成功
2。现在我调用personRepository.findByName：它可以工作！
Indeed, if I do the following: 1. Call a non-transactional method on the ejb (@TransactionAttributeType.NEVER): this call succeeds 2. Now I do call the personRepository.findByName: it works!
因此问题似乎是在正在进行CMT事务时，Spring JPA存储库无法注册其命名查询。
So the issue seems like that Spring JPA repositories fail to register their named queries when there is an ongoing CMT transaction.
这听起来有人熟悉吗？也许有一种方法可以避免在交易环境中初始化这些存储库？ （我尝试使用@Eager批注，但在此情况下未更改任何内容。）。
Does this sounds familiar to someone ? Perhaps there is a way to avoid those repositories to be initialized within a transactional context ? (I tried @Eager annotation, but does not change anything in this context).
p.s。其他信息：切换到Hibernate 3.6.10.Final作为JPA Provider是解决此问题的方法。我越努力，就越相信Spring Data JPA和Eclipselink之间的错误（我都尝试了Eclipselink 2.3（嵌入在Weblogic中）和2.5.2）。
p.s. another bit of information: switching to Hibernate 3.6.10.Final as JPA Provider is a workaround to this issue. The more I work on this the more I believe could be a bug between Spring Data JPA and Eclipselink (I both tried Eclipselink 2.3 (embedded in Weblogic) and 2.5.2).
推荐答案
我想添加一个我发现的解决方法：切换到Hibernate 3.6.10.Final，因为JPA Provider解决了该问题。
I would like to add this workaround I found: switching to Hibernate 3.6.10.Final as JPA Provider fixes the issue.
此开关只需要更改persistece.xml文件，如下所示：
This switch requires just to change the persistece.xml file, as follows:
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
<persistence-unit name="MyPersistenceUnit" transaction-type="JTA">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<jta-data-source>db/myprojectdatasource</jta-data-source>
<class>myproject.dao.entities.Person</class>
<properties>
<property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect" />
<property name="hibernate.transaction.manager_lookup_class"
value="org.hibernate.transaction.WeblogicTransactionManagerLookup" />
<property name="hibernate.show_sql" value="true" />
</properties>
</persistence-unit>
</persistence>
在春季，您仍然拥有 EntityManagerFactory 从JNDI上下文和 JtaTransactionManager 查找。
While in Spring you still have the EntityManagerFactory looked up from the JNDI context and the JtaTransactionManager .
请注意，我明确地省略了设置JtaFactoryClass
Note that I am explicitly omitting to set the JtaFactoryClass
<属性名称= hibernate.transaction.factory_class value = org.hibernate.transaction.JTATransactionFactory />
休眠状态：如果出于某些原因，Weblogic事务管理器会在执行事务之前禁用自动提交。
property on hibernate: if I do so, for some reasons, Weblogic Transaction Manager disables auto-commit before executing transactions.
这篇关于Spring 4.0.6 + Weblogic 10.3.6 + EJB 3.0 CMT + Spring Data JPA 1.6.2的事务异常-“错误绑定到外部管理的事务”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！
