在 JBoss 7.1.1 的这个模块中已经定义了一个名为“XXX"的组件 [英] A component named 'XXX' is already defined in this module in JBoss 7.1.1

问题描述

我没有在我的应用程序中使用 TimerServiceDispatcher 创建 spring bean 名称.但是，由于TimerServiceDispatcher 导致的JBoss 抛出异常已经在该模块中定义.我不知道是什么问题.我缺少什么?我需要做什么?

I did not create the spring bean name with TimerServiceDispatcher in my application. But, the JBoss throw exception because of TimerServiceDispatcher is already defined in this module. I don't know what is the problem. What I am missing? What I need to do?

我的应用程序使用 Seam 2.3、Spring 3.0 和 JPA 2.0.我不使用 EJB.

My application use Seam 2.3, Spring 3.0 and JPA 2.0. I don't use EJB.

推荐答案

我有一个用 @Singleton 和 @Stateless 注释的 bean 触发了这个错误.我的代码当然是错误的，但像这样的消息和帖子让我走上了一段错误的道路.

I had a bean annotated with @Singleton and @Stateless that triggered this error. My code was of course wrong but the message and posts like this lead me down the wrong path for a while.
