Question

社区。我正在开始使用Spring框架，我只是想完成一个Hello World Web应用程序。但是当我尝试运行应用程序时发生了这些错误。

我已经阅读了很多解决方案，但没有一个没有帮助。我使用：maven，spring 5.0.4，IntelijIDEA，Tomcat 8.5.29

我知道Spring Context命名约定[servlet-name] -servlet.xml是什么，但它没有帮助

Answer 1

从/web值

中删除contextConfigLocation

<servlet>
  <servlet-name>HelloWeb</servlet-name>
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  <init-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/applicationConfig.xml</param-value>
  </init-param>
  <load-on-startup>1</load-on-startup>
</servlet>

作为WAR文件应该有一个顶级WEB-INF目录，而不是web/WEB-INF。

简化您的maven-war-plugin配置，因为您可以按原样包含资源，而不进行过滤：

<configuration>
  <webResources>
    <resources>
      <directory>WebContent</directory>
    </resources>
  </webResources>
</configuration>

根据this answer，您可能希望使用src/main/webapp代替WebContent。

无法打开ServletContext资源（Spring）
