以上是我的POM.xml。我的Apache日志说......

3 个答案:

答案 0 :(得分：3)

答案就在这一行：

  

java.lang.ClassNotFoundException: org.springframework.web.servlet.DispatcherServlet

基本上，您的Web应用程序缺少Spring Core和/或Spring MVC的JAR文件。它们应该位于webapp的/WEB-INF/lib目录中，以及您的webapp所依赖的其他JAR文件。看看那里有什么，并试着找出为什么DispatcherServlet缺失。

答案 1 :(得分：1)

如果您正在使用IDE并尝试从ide中运行它，则需要明确告知ide将maven依赖项导出到web-inf / lib

如果你正在使用eclipse; 项目属性 部署大会 添加 - ＆gt; Maven依赖并告诉eclipse将它们导出到web-inf / lib

答案 2 :(得分：0)

我不熟悉使用Maven作为弹簧应用程序，但只是一眼就看出你正在拉下测试架构而不是实际的弹簧二进制文件。这也与您获得的错误一致：它找不到DispatcherServlet类。我会仔细检查以确保您的POM.xml中列出了正确的spring依赖关系
