更新：我分析了新的pom.xml，我可以看到你的請求處理程序是沒有得到出於某些原因，「setConfigLocation」註冊，因爲不能找到WebConfig。

這使它適合我。在getContext函數中添加此行WebAppInitalizer.java類。

我能複製相同的配置，使應用程序的工作。

謝謝回答這個問題。 :) 你的pom.xml不適合我。我包含了我的pom.xml代碼。如果你找到任何解決方案，它會很好。盡我所能，我的RequestMapping或ComponentScan不能正常工作。但我不知道代碼中哪一個和哪個錯誤。 @Neeraj – NAZ

我分析了你的新pom.xml，我可以看到你的請求處理程序沒有被註冊，因爲「setConfigLocation」無法找到WebConfig。這使它適合我。在WebAppInitalizer.java類的getContext函數中添加此行。 context.register（com.naz.WebConfig.class）; 參考這裏： http://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/web/WebApplicationInitializer.html – Neeraj
