Java Spring单例在发生JNDI DataSourceBinding之前实例化

我是JavaEE的新手，我有一些问题，在绑定JNDI之前实例化了具有JndiObjectFactoryBean属性的spring单例。它会导致部署错误，并使应用程序部署失败

是否仍然需要配置初始化的优先级？比如在spring单例之前先实例化JNDI DataSourceBinding

我使用jboss-5.1.0.GA作为我的应用服务器

以下是server.log的片段：

只有在长堆栈跟踪错误之后，才会实例化所需的JNDI绑定

2015-05-25 16:47:16,759 INFO  [org.jboss.resource.connectionmanager.ConnectionFactoryBindingService] (main) Bound ConnectionManager 'jboss.jca:service=DataSourceBinding,name=cxcdataDS' to JNDI name 'java:cxcdataDS'

如果有人能帮我，我会非常感激的。

谢谢

最后，由于部署过程中的问题，在绑定JNDI之前，单例被实例化，出于某种原因，应用程序被部署到JBoss的.sar文件夹中。因此，在实例化JNDI之前加载应用程序。

在我将应用程序移动到正确的文件夹后，它会像以前一样正常运行。

我不确定，但是，您是否尝试在您的CXC\u Security.xml中使用as-JNDI名称java:cxcdataDS而不是cxcdataDS？Hi@Vartlok，感谢您的帮助。幸运的是，我找到了问题的原因。JNDI命名本身没有问题，只是部署问题。
