警告：在名爲'appServlet'的DispatcherServlet中沒有找到具有URI [/ SpringMVCHibernate /]的HTTP請求的映射

Question

您好傢伙，我在啓動服務器後出現以下錯誤。任何人都可以請幫我解決如何處理這個錯誤？我正在使用ECLIPSE Luna和彈簧 4.0.3。是否有任何與特定彈簧版本eclipse LUNA我需要使用？

WARN : org.springframework.web.servlet.PageNotFound - No mapping found for HTTP request with URI [/SpringMVCHibernate/] in DispatcherServlet with name 'appServlet'

Answer 1

如果您使用的是IDE（蝕）， '在服務器上運行' 選項打開瀏覽器，嘗試加載基本映射（http://localhost:8080/SpringMVCHibernate/）。在正常的Web應用程序中，根據web.xml配置加載主頁（index.html）。

在您的spring控制器中，沒有映射對應於基本映射，如@RequestMapping(value= "/", method = RequestMethod.GET)。由於您的servlet-mapping的url-pattern是/，所有請求必須在我的調度程序servlet中處理。但是沒有映射http://localhost:8080/SpringMVCHibernate/。

備註：只有在/SpringMVCHibernate/person等其他映射工作正常的情況下，此答案才能解決問題。
