獲取資源404不可用tomcat

我想在Spring MVC中開發一個HelloWorld示例，我已經知道Java，但在新的春天，我正在遵循這個教程點教程：https://www.tutorialspoint.com/spring/spring_mvc_hello_world_example.htm 我有一些問題，但在有一刻它正常工作，然後我轉到下一個教程，然後它不再工作，即使我刪除了所有新文件，但我找不到原因。（我只是指出了教程的改變，以防這是原因，但也許這不相關）。獲取資源404不可用tomcat

，尤其是圓形是我的web.xml

<web-app id = "WebApp_ID" version = "2.4" 
xmlns = "http://java.sun.com/xml/ns/j2ee"

<servlet-mapping> 
    <servlet-name>HelloWeb</servlet-name> 
    <url-pattern>/</url-pattern> 
</servlet-mapping> 

</web-app>

public class HelloController { 
    @RequestMapping(method = RequestMethod.GET) 
    public String printHello(ModelMap model) { 
     model.addAttribute("message", "Hello Spring MVC Framework!"); 
     return "hello"; 
    } 
}

    <body> 
     <h2>${message}</h2> 
    </body> 
</html>

我的目錄 Directories

給Tomcat中部署它，我只是不右鍵單擊在Eclipse>出口> WAR文件的項目，並將其保存在Tomcat的webapps文件夾，裏面我有詹金斯戰爭也和詹金斯作品好的，我可以看到Tomcat的主頁也可以，所以我認爲這不是一個Tomcat問題，但我願意接受建議。

然後我去localhost:8080/HelloWeb/hello，我得到的錯誤。我已經搜索了一些日子，我發現任何解決方案都爲我工作。

我有錯誤

Multiple annotations found at this line: 
- cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'mvc:annotation-driven'. 
- schema_reference.4: Failed to read schema document 'springframework.org/schema/mvc/spring-mvc.xsd', because 1) could not find the document; 
2) the document could not be read; 3) the root element of the document is not <xsd:schema>.

12行

<mvc:annotation-driven />

您還沒有啓用在的HelloWeb-servlet.xml中的註釋，請添加以下代碼之前

<context:annotation-config />

<context:component-scan base-package = "com.tutorialspoint" />

感謝您的回覆，但它並沒有爲我工作：/ –

我錯過了，不過您需要在HelloWeb-servlet.xml中添加，並且您的bean配置需要引用/更新爲xmlns：mvc =「http://www.springframework.org/schema/mvc」xsi： schemaLocation =「http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd」 –

我剛編輯問題以回覆喲你的回答，我仍然有一個錯誤。 –
