Question

我是Java EE的新手，我有一些问题，在绑定JNDI本身之前，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。

无论如何配置初始化的优先级？比如让JNDI DataSourceBinding在Spring单例之前首先实例化？

我使用jboss-5.1.0.GA作为我的应用程序服务器。

以下是server.log的片段：

...

并且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'

如果有人可以帮助我，我真的很感激。感谢

最后，由于部署期间的问题，单个JNDI绑定之前实例化单例，由于某种原因，应用程序被部署到属于JBoss的.sar文件夹内。因此，在实例化JNDI之前加载应用程序。将我的应用程序移动到正确的文件夹后，它正好像以前一样运行。

在JNDI DataSourceBinding发生
