java - 未找到带有 URI [/webstore] 的 HTTP 请求的映射

Question

当我尝试在 tomcat 服务器上运行我的 spring 应用程序时遇到问题。我在浏览器中收到错误 404，在控制台中收到此错误:

2016-05-09 12:26:03,188 INFO org.hibernate.tool.hbm2ddl.SchemaExport -  HHH000230: Schema export complete
2016-05-09 12:26:05,082 INFO org.springframework.web.servlet.DispatcherServlet - FrameworkServlet 'DispatcherServlet': initialization completed in 5685 ms
2016-05-09 12:26:05,121 WARN org.springframework.web.servlet.PageNotFound - No mapping found for HTTP request with URI [/webstore/] in DispatcherServlet with name 'DispatcherServlet'

这是我的 web.xml 文件:

你能告诉我问题出在哪里吗？这很奇怪，因为我不是唯一使用此代码的人，而且只有我遇到这个问题......

哦。我的 DispatcherServlet.xml 看起来像这样:

<?xml version="1.0" encoding="UTF-8"?>

您需要在应用程序服务器中检查以下几点:

• 是否有任何部署错误消息？
• 应用程序已部署但具有不同的上下文？ (例如 / 而不是 /webstore)
• 您是否拥有应用程序服务器的多个副本，但您正在运行一个副本并尝试在另一个副本中部署您的应用程序？
