我在stackoverflow中搜索了一些页面来解决这个问题，确实遵循了一些真实的答案，但没有奏效。我是 Spring 的新人，对不起。这是我的调度程序-servlet

删除 2 行:

 <context:component-scan base-package="controller" />
      <mvc:annotation-driven />

然后项目正常运行。不知道为什么……

最佳答案

我遇到了同样的问题。我看了好几个小时。我找不到任何问题。然后我决定，如果你使用不同的编辑器，有时你会看到不同的东西。我关闭了 Netbeans 并在 emacs 中打开了文件。我立即看到，有某种不间断的空格字符，或制表符，或某种不是空格的空格。我不知道它是哪个字符，但它在 emacs 中显示为红色，但在 Netban 中显示为空白
