无法将 Spring mvc 部署到 intellij 中的 tomcat

Question

我正在尝试在 IntelliJ 中将没有 spring boot 的简单 spring MVC 项目部署到 tomcat，但我无法让它工作，服务器总是返回 404。我尝试了很多教程，但它仍然不起作用。

我也尝试过 AbstractAnnotationConfigDispatcherServletInitializer 类，但它也不起作用。似乎onStartup从未调用过该方法。

有人可以指出我错在哪里并让它发挥作用吗？

这是我的 pom.xml 文件

Answer 1

首先，您应该添加<packaging>war</packaging>到您的pom.xml中，但这不会导致错误。pom.xml<groupId>com.learning</groupId><artifactId>spring-web-no-boot</artifactId><version>1.0-SNAPSHOT</version><packaging>war</packaging>您正在使用两种不同的上下文。如果您仅使用根上下文，它应该可以工作。尝试以下 Application.java：public class Application implements WebApplicationInitializer {&nbsp; &nbsp; public void onStartup(ServletContext container) throws ServletException {&nbsp; &nbsp; &nbsp; &nbsp; AnnotationConfigWebApplicationContext context =&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; new AnnotationConfigWebApplicationContext();&nbsp; &nbsp; &nbsp; &nbsp; context.setConfigLocation("configuration");&nbsp; &nbsp; &nbsp; &nbsp; container.addListener(new ContextLoaderListener(context));&nbsp; &nbsp; &nbsp; &nbsp; ServletRegistration.Dynamic dispatcher =&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; container.addServlet("dispatcher", new DispatcherServlet(context));&nbsp; &nbsp; &nbsp; &nbsp; dispatcher.setLoadOnStartup(1);&nbsp; &nbsp; &nbsp; &nbsp; dispatcher.addMapping("/");&nbsp; &nbsp; }}

Answer 2

我认为下面的行可能是问题@ComponentScan(basePackages&nbsp;=&nbsp;"controller")你能试着把它改成@ComponentScan(basePackages&nbsp;=&nbsp;{"controller"})
