的Spring MVC模板項目我下面教程http://krams915.blogspot.ie/2011/01/spring-mvc-3-hibernate-annotations.html在Spring工具套件
我有麻煩，當我輸入localhost：8080 /教程/ krams /主/人到地址欄。我不斷收到404錯誤。我的頂級軟件包是org.krams.tutorial，我已經將該項目的名稱設置爲教程。我刪除了Home Controller.java和home.jsp，我不確定這是否會產生影響Spring MVC模板的目錄結構與Krams不同，當我下載Krams項目並在STS中運行它時，它工作正常，但我想從頭開始自己做。希望有人能幫助我！它非常令人沮喪！ 這是我的代碼。
