私はいくつかの問題を抱えています。Spring MVC Maven と Hibernate で構成される Spring Tool Suit を使用してアプリケーションを構築しています。私は春に慣れていないにもかかわらず、すべてのコーディングがうまくいっているか、うまくいっていると思います。
ここに私のプロジェクトの2つの画面を置きます:

更新 1:
こんにちは、私はこの解決策を適用しました：
First, your @Controller class is in
package controller;
so your DispatcherServlet config needs to have a component-scan on that package. So change yours to
<context:component-scan base-package="controller"/>
So that the <mvc:annotation-driven> gets applied and your @Controller class is added as a handler.
Now even if you do this, you still don't seem to have a handler method for the path
/ChickenTest/index.jsp
You'll want to either add a <welcome-file> to your web.xml and an index.jsp file in your /webapps folder or add a @RequestMapping handler method that can handler /index.jsp.
しかし、コンソールは GeneralController.class の @Autowire が機能していないことを教えてくれます。
これは私の新しいエラーです:
SEVERE: Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'generalController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: com.chicken.service.EggService com.chicken.controller.GeneralController.eggService; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.chicken.service.EggService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
