我得到了404錯誤,我的第一個spring mvc應用程序,遵循所有的配置,但沒有運氣。你能幫忙解決問題嗎?獲取org.springframework.web.servlet.PageNotFound noHandler發現錯誤

在服務器控制檯我得到以下警告:
org.springframework.web.servlet.PageNotFound noHandlerFound
WARNING: No mapping found for HTTP request with URI [/HereWeGo/] in DispatcherServlet with name 'spring-dispatcher'
我的項目名稱是HereWeGo。
刪除指定的註釋並以「/ welcome」訪問,獲得相同的響應並出現以下錯誤。 ** org.springframework.web.servlet.PageNotFound noHandlerFound ** **警告:否的DispatcherServlet找到HTTP請求與URI [/ HereWeGo /歡迎]名爲 '彈簧調度' 映射** –
請嘗試本地主機:8080/com.aditya.spring /歡迎如果8080是您的服務器端口,並讓我知道它的工作 –
沒有運氣,多一個觀察:也給404頁。 –
