警告:在名称为 'appServlet' 的 DispatcherServlet 中找不到带有 URI [/SpringMVCHibernate/] 的 HTTP 请求的映射
WARN: No mapping found for HTTP request with URI [/SpringMVCHibernate/] in DispatcherServlet with name 'appServlet'
大家好,我在启动服务器后遇到以下错误。谁能帮我解决这个错误?我正在使用 ECLIPSE Luna 和 spring
4.0.3。我需要使用 eclipse LUNA 的特定 spring 版本吗?

如果您使用的是 IDE(eclipse),'run on server' 选项会打开浏览器并尝试加载基本映射 (http://localhost:8080/SpringMVCHibernate/)。在普通的 Web 应用程序中,这会根据 web.xml
配置加载主页 (index.html)。
在你的spring控制器中,没有像@RequestMapping(value= "/", method = RequestMethod.GET)
这样的基础映射对应的映射。由于您的 servlet-mapping
的 url-pattern
是 /
,所有请求都必须由我的调度程序 servlet 处理。但是 http://localhost:8080/SpringMVCHibernate/
.
没有映射
注意:仅当 /SpringMVCHibernate/person
等其他映射正常工作时,此答案才能解决问题。
