我创建了spring config，其中applicationContext包含所有'重'bean和 servlet上下文只有控制器。我的问题是所有'大'bean的applicationContext被加载两次。我做错了什么？
我的web.xml

更新
当我在applicationContext和web.xml中注释每个东西（没有listener和context-param）之后，我的tomcat输出看起来像这样：

显示两次。
答案 0 :(得分：0)
我对这个问题打了很多。我几乎禁用了所有东西，但它仍然存在。 然后我回到我的eclipse tomcat配置，我设置'使用真实安装'。 当我将设置更改为使用“使用工作区元数据”后问题消失。
我正在使用 eclipse luna release 2 和 tomcat 8
我希望这可以节省时间。
<强>更新
经过几次尝试后，我发现eclipse正在破坏我的tomcat安装。 （我尝试了一个新的确保）。当我设置'使用真正的安装'时 问题再次发生。在此之后，即使我在没有eclipse的情况下运行tomcat，它仍然存在。
解决方案是：删除你的tomcat安装。设置一个新的并且永远不会改变'使用工作空间元数据'
