JBoss5.0下启动Struts2+spring+hibernate项目

来源：百度文库编辑：神马文学网时间：2024/05/03 06:06:10

Jboss5.0.0下，项目使用Struts2.1.6+Spring2.5.5+Hibernate3（使用JPA的Hibernate实现）框架，但是在Jboss下启动时总是抛出“java.lang.RuntimeException: Specification violation [EJB3 JPA 6.2.1.2] - You have not defined a non-jta-data-source for a RESOURCE_LOCAL enabled persistence context named: esys”的错误，错误信息如下：
15:38:56,359 INFO [PersistenceUnitDeployment] Starting persistence unit persistence.unit:unitName=#esys
15:38:56,375 ERROR [AbstractKernelController] Error installing to Start: name=persistence.unit:unitName=#esys state=Create

反编译了jboss安装目录下common\lib中的“jboss-jpa-deployers.jar”文件，发现此文件中抛出异常的“PersistenceUnitInfoImpl”类，有这么几句代码：
if (metaData.getProvider() != null) { setPersistenceProviderClassName(metaData.getProvider());
}
if (metaData.getJtaDataSource() != null)
{
setJtaDataSource((DataSource)ctx.lookup(metaData.getJtaDataSource()));
}
else if (transactionType == PersistenceUnitTransactionType.JTA)
{
throw new RuntimeException("Specification violation [EJB3 JPA 6.2.1.2] - You have not defined a jta-data-source for a JTA enabled persistence context named: " + metaData.getName());
}
if (metaData.getNonJtaDataSource() != null)
{
setNonJtaDataSource((DataSource)ctx.lookup(metaData.getNonJtaDataSource()));
}
else if (transactionType == PersistenceUnitTransactionType.RESOURCE_LOCAL)
{
throw new RuntimeException("Specification violation [EJB3 JPA 6.2.1.2] - You have not defined a non-jta-data-source for a RESOURCE_LOCAL enabled persistence context named: " + metaData.getName());
}
按照这个意思就是persistence.xml中必须至少配置一个JNDI数据源，但是我使用的是spring管理的数据源，这个地方怎么会出现这种问题呢？

问题补充：
persistence.xml中“persistence-unit”是必须的，而且必须与applicationContext中指定的“persistenceUnitName”同名，再加上系统不使用JTA事物，transaction-type="RESOURCE_LOCAL"好像也是必须。其他的配置信息曾经去掉过，可是不起作用。倒是在persistence.xml中加上一个空的启动的时候不再抛异常了。
