更新：我分析了您的新pom.xml，发现您的请求处理程序没有注册，因为出于某种原因，“setConfigLocation”无法找到WebConfig

这对我来说很有用。在

webappinitializer.java

类的

getContext

函数中添加此行

context.register(com.naz.WebConfig.class);

参考是

我能够复制相同的配置并使应用程序工作

谢谢您回答这个问题。：）你的pom.xml不适合我。我将讨论我的pom.xml代码。如果你能找到解决办法，那就太好了。我认为我的RequestMapping或ComponentScan不能正常工作。但是我不知道是哪一个&代码有什么问题@NeerajI分析了您的新pom.xml，我发现您的请求处理程序没有注册，因为出于某种原因，“setConfigLocation”无法找到WebConfig。这对我来说很有用。在WebAppInitializer.java类的getContext函数中添加此行。register（com.naz.WebConfig.class）；参考资料如下：
