Anottations在Spring MVC/Maven的不工作

Question

我遇到此問題時，嘗試訪問本地主機URI http://localhost:8080/spring/olaMundoSpring它是在瀏覽器返回：

狀態404所請求的資源不可用。

和：

沒有映射找到用於與URI HTTP請求[/彈簧/ olaMundoSpring]在> DispatcherServlet的名稱爲 'Spring MVC的分派器的Servlet'。

彈簧context.xml中似乎是好的：

設定05年，2016年下午9時45分24秒> org.springframework.beans.factory.xml.XmlBeanDefinitionReader> loadBeanDefinitions INFORMAÇÕES：從ServletContext的資源[/WEB->INF/spring-context.xml]

控制器加載XML bean定義：

package br.com.jayybe.spring; 

import org.springframework.stereotype.Controller; 
import org.springframework.web.bind.annotation.RequestMapping; 

@Controller 
public class Controle { 

    @RequestMapping("/olaMundoSpring") 
    public String execute() { 
     System.out.println("Executando a lógica com Spring MVC"); 
     return "ok"; 
    } 
} 

的web.xml：

<web-app> 
    <display-name>Archetype Created Web Application</display-name> 

<servlet> 
     <servlet-name>Spring MVC Dispatcher Servlet</servlet-name> 
     <servlet-class>

    <servlet-mapping> 
     <servlet-name>Spring MVC Dispatcher Servlet</servlet-name> 
     <url-pattern>/</url-pattern> 
</servlet-mapping> 
</web-app> 

彈簧context.xml中：

試着改變你的註釋是這樣的：

@RequestMapping(value = "/olaMundoSpring", method = RequestMethod.GET) 

更改組件掃描：

<context:component-scan base-package="br.*" /> 

而且不要用白色使用名稱用於servlet映射的空間
