No JTA UserTransaction available - specify either 'userTransaction' or 'userTransactionName'
提问by Chir
I have encountered a strange problem with spring transaction. My application uses Spring with EJBs. The EJBs also invoke Spring service classes annotated with @Transaction. I have used Spring JtaTransactionManagerfor transaction management. The application is packaged as an EAR file and is deployed on jboss5.0 and it works fine. But when I instruct jboss to use separate classloader for each EAR application, spring initialization gives error.
我在spring事务中遇到了一个奇怪的问题。我的应用程序使用带有 EJB 的 Spring。EJB 还调用带有@Transaction. 我使用 SpringJtaTransactionManager进行事务管理。应用打包为EAR文件，部署在jboss5.0上，运行正常。但是当我指示 jboss 为每个 EAR 应用程序使用单独的类加载器时，spring 初始化会出错。
org.springframework.beans.factory.BeanCreationException: Error creating bean
with name 'transactionManager' defined in ServletContext resource
[/WEB-INF/applicationContext.xml]: Invocation of init method failed;
nested exception is java.lang.IllegalStateException: No JTA UserTransaction
available - specify either 'userTransaction' or 'userTransactionName' or
'transactionManager' or 'transactionManagerName'
Why initialization of Spring is not successful?
为什么Spring初始化不成功？
Thanks

try adding
尝试添加
@EnableTransactionManagement
on a configuration class where you hold your config bean
在您保存配置 bean 的配置类上
that worked for me when i had that issue , maybe you will need other platform specific implementation of the transaction manager , but this is a good place to start.
当我遇到这个问题时，这对我有用，也许您需要事务管理器的其他平台特定实现，但这是一个很好的起点。
@Bean
public PlatformTransactionManager transactionManager() {
JpaTransactionManager txManager = new JpaTransactionManager();
txManager.setEntityManagerFactory(entityManagerFactory());
return txManager;
}
