我现在正在学习Spring，所以我面临上述问题，所以请为我提供一个解决方案，当我理解这个问题后，我将使用注释

我推荐以下链接：

这个设置对我很有用：

删除bean名称中的´/´。嗨，我像你说的那样试过了，但是仍然得到同样的错误，顺便说一句，我已经更新了stacktrace上面的内容。。。请检查一下，如果可能的话，请从你这边跑开。是的，这不是唯一的问题，我调查了一下。你看过这个帖子吗？你是说我要把“/”从这个标签上去掉，对吗，这里：我照你说的做了，但是我还是得到了和上面一样的错误…我试着用两种形式。。我不明白还需要做哪些更改，你能在我的xml文件中找到其他错误吗？那么，我们不能在不使用application-context.xml文件的情况下使用应用程序吗？这是一个必须的文件吗？？顺便说一句，我用你上面的代码运行，现在会让你知道。顺便说一句，我需要使用这个吗？此链接中的org.springframework.web.context.ContextLoaderListener给定：不，不是。您可以在每个context.xml中使用import语句。按照惯例，命名顶级context.xml

application context.xml

并从那里开始工作。@Irwin请阅读，以了解DispatcherServlet的功能以及我如何（等等）编辑到我的答案中。当然，我肯定会阅读该链接，现在我有疑问，我现在是否应该使用导入，既然我在使用ContextLoaderListener，如果你不介意的话，你能给我看看你的应用程序的代码吗？context.xml和web.xml文件（完整更新的代码）
