缺少映射到控制器的請求。 Spring MVC

Question

向控制器執行請求時，顯示錯誤404。 我不明白我做錯了什麼。

下面發佈的web.xml，* -servlet.xml，控制器類。

的web.xml

<?xml version="1.0" encoding="UTF-8"?> 
<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" 
     version="3.0" metadata-complete="false"> 
    <context-param> 
    <param-name>contextConfigLocation</param-name> 
    <param-value>/WEB-INF/golfing-servlet.xml</param-value> 
    </context-param> 
    <servlet> 
    <servlet-name>golfing</servlet-name> 
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 
    <load-on-startup>1</load-on-startup> 
    </servlet> 
    <servlet-mapping> 
    <servlet-name>golfing</servlet-name> 
    <url-pattern>/golfing/*</url-pattern> 
    </servlet-mapping> 
    <listener> 
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 
    </listener> 

</web-app> 

通訊高爾夫-servlet.xml中

<beans xmlns="http://www.springframework.org/schema/beans" 
     xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     xsi:schemaLocation=" 
     http://www.springframework.org/schema/beans 
     http://www.springframework.org/schema/beans/spring-beans.xsd 
     http://www.springframework.org/schema/mvc 
     http://www.springframework.org/schema/mvc/spring-mvc.xsd 
     http://www.springframework.org/schema/context 
     http://www.springframework.org/schema/context/spring-context.xsd"> 

    <mvc:default-servlet-handler/> 

    <context:component-scan base-package="com.vlad.home.controllers.*" /> 

    <bean id="viewResolver" 
      class="org.springframework.web.servlet.view.UrlBasedViewResolver"> 
     <property name="viewClass" 
        value="org.springframework.web.servlet.view.JstlView" /> 
     <property name="prefix" value="/WEB-INF/jsp/" /> 
     <property name="suffix" value=".jsp" /> 
    </bean> 

</beans> 

和控制器類

@Controller 
@RequestMapping("/") 
public class TestController { 

    @RequestMapping(value = "/test", method = RequestMethod.GET) 
    public ModelAndView render() { 
     System.out.println("WAS CALLED CONTROLLER METHOD render()"); 
     ModelAndView modelAndView = new ModelAndView("test"); 
     return modelAndView; 
    } 

    @RequestMapping(value = "/*") 
    public ModelAndView others() { 
     System.out.println("WAS CALLED CONTROLLER METHOD others()"); 
     ModelAndView modelAndView = new ModelAndView("test"); 
     return modelAndView; 
    } 

} 

而且在tomcat的輸出控制檯日誌錯過映射URL路徑我的控制器，所以很奇怪。

我真的不明白錯誤的地方在哪裏。

現在結構有一定的另一視圖：

Web.xml中

</beans> 

和JDBC-servlet.xml中

<beans xmlns="http://www.springframework.org/schema/beans" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc" 
     xmlns:context="http://www.springframework.org/schema/context" 
     xsi:schemaLocation="http://www.springframework.org/schema/beans 
     http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> 

    <mvc:default-servlet-handler/> 

    <context:component-scan base-package="com.vlad.home.controllers.or"/> 

    <mvc:resources mapping="/resources/**" location="/WEB-INF/resources/"/> 
</beans> 

<mvc:annotation-driven/>是需要applicationContext.xml
