Java SpringJDBCMVC项目提供404

我已经和Spring框架斗争了几个星期了，我得到了 一个普通的MVC页面显示出来，我让JDBC打印到控制台上。 但我似乎不能让这些一起工作

在这一点上，我已经通过了无数的教程，每一个都是如此 似乎有某种类型的错误或问题

我想我终于成功地建立了一个相当体面和工作的建设，但没有，仍然只有404的

我认为问题可能出在spring-servlet.xml文件中：

<context:component-scan base-package="src" />

及

pom.xml

不是我的答案，而是解决这个问题的答案，因为它深深地隐藏在评论中，所以作为答案发布

抱歉耽搁了。。。。还是不对。我知道是因为
Eclipse不应将包显示为main.java.controller。。。。专家
忽略该文件夹并按原样从java文件夹下开始
src文件夹本身。你的项目一定出了问题。尝试
清理一切，从eclipse中删除项目，删除
（物理）文件夹.settings和文件.classpath以及文件
项目在控制台上执行文件夹项目并运行mvn clean
eclipse:clean然后打开if的所有文件夹（如我向其显示的图像）
你）和粘贴在这里，这样我就可以看到它是错的

您是否使用m2e maven/eclipse插件？此项目是否作为maven项目导入？至少对我来说，Maven将所有内容都放在
src/main/java///
下，而不仅仅是src。还有，你为什么使用xml配置而不是java配置？你是如何运行你的应用程序的？@artemisian right click->run as server（tomcat9）我也有单独的linux服务器和tomcat9，我使用它在没有eclipse的情况下部署，两者都不起作用。你能在创建war文件时发布它的结构图像吗，运行“mvn package”。war文件可以由文件压缩程序/解压缩程序应用程序作为WinRar打开。这是maven web项目的适当结构：在webapp文件夹中，它应该有web-INF和资源。您是否使用m2e maven/eclipse插件？此项目是否作为maven项目导入？至少对我来说，Maven将所有内容都放在
