在 JNDI DataSourceBinding 发生之前实例化 Spring 单例答案

【问题标题】：Spring singletons is instantiated before JNDI DataSourceBinding occured在 JNDI DataSourceBinding 发生之前实例化 Spring 单例

【问题描述】：

我是 Java EE 的新手，我遇到了一些问题，即在绑定 JNDI 本身之前实例化具有 JndiObjectFactoryBean 属性的弹簧单例。导致部署出错，导致应用部署失败。

有没有配置初始化的优先级？比如让JNDI DataSourceBinding在spring singletons之前先实例化？

我使用 jboss-5.1.0.GA 作为我的应用服务器。

这里是server.log的sn-p：

2015-05-25 16:47:14,410 INFO  [org.springframework.beans.factory.support.DefaultListableBeanFactory] (main) Pre-instantiating singletons in org.springframework.beans.factory.support.DefaultListableBeanFactory@1f873f7: defining beans [daoAuthenticationProvider,authenticationManager,settingbean,authenticationFailureHandler,authenticationSuccessHandler,sessionRegistry,sessionAuthenticationStrategy,authenticationFilter,sessionManageProcessingFilter,httpSessionContextIntegrationFilter,filterChainProxy,securityContextPersistenceFilter,filterSecurityInterceptor,httpRequestAccessDecisionManager,roleVoter,cxcdataDS,datasourceByJNDI,JTATransactionManager,jdbcTXManager,jdbcTemplate,jdbcTemplateext]; root of factory hierarchy

...

只有在长堆栈跟踪错误之后，所需的 JNDI 绑定才会被实例化

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'

如果有人可以为此提供帮助，我将不胜感激。谢谢

【问题讨论】：

我不确定，但是您是否尝试过在您的CXC_Security.xml 中使用java:cxcdataDS 而不是cxcdataDS 作为JNDI 名称？
嗨@Vartlok，感谢您提供帮助。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。

【解决方案1】：

由于部署期间的问题，最终在绑定 JNDI 之前实例化了单例，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，它可以像以前一样正常运行。
