Anottations在Spring MVC/Maven的不工作

Question

我遇到此问题时，尝试访问本地主机URI http://localhost:8080/spring/olaMundoSpring它是在浏览器返回：

状态404所请求的资源不可用。

和：

没有映射找到用于与URI HTTP请求[/弹簧/ olaMundoSpring]在> DispatcherServlet的名称为 'Spring MVC的分派器的Servlet'。

弹簧context.xml中似乎是好的：

设定05年，2016年下午9时45分24秒> org.springframework.beans.factory.xml.XmlBeanDefinitionReader> loadBeanDefinitions INFORMAÇÕES：从ServletContext的资源[/WEB->INF/spring-context.xml]

控制器加载XML bean定义：

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> 

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

弹簧context.xml中：

Answer 1

试着改变你的注释是这样的：

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

更改组件扫描：

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

而且不要用白色使用名称用于servlet映射的空间
