HTTP狀態404運行控制器上的Spring MVC錯誤

我無法在Spring MVC tomcat 7.0.56中運行控制器，因爲它每次顯示「HTTP Status 404 error」。 Spring MVC可以在WEB-INF內運行welcome.jsp，但不能從控制器的路徑運行。 '/你好'。我已經從SO查看了幾篇文章，以找出這個但沒有運氣。我在這裏做錯了什麼？下面是我的代碼：HTTP狀態404運行控制器上的Spring MVC錯誤

項目結構：

的web.xml

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

    <welcome-file-list> 
    <welcome-file>/WEB-INF/jsp/welcome.jsp</welcome-file> 
    </welcome-file-list> 


    <servlet> 
    <servlet-name>SpringMVC</servlet-name> 
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 
    <load-on-startup>1</load-on-startup> 
    </servlet> 

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

</web-app>

用SpringMVC-servlet.xml中

<context:component-scan base-package="org.spring"></context:component-scan> 

    <context:annotation-config></context:annotation-config> 
    <mvc:annotation-driven /> 

    <mvc:default-servlet-handler/> 

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

springController.java

package org.spring; 

    import org.springframework.stereotype.Controller; 
    import org.springframework.ui.Model; 
    import org.springframework.web.bind.annotation.RequestMapping; 
    import org.springframework.web.bind.annotation.RequestMethod; 
    import org.springframework.web.servlet.ModelAndView; 

    @Controller 
    public class SpringController { 

     @RequestMapping(value = "/hello") 
    public ModelAndView helloworld() { 
     ModelAndView model = new ModelAndView("welcome"); 
     return model; 
    } 
    }

的welcome.jsp

<%@ page language="java" contentType="text/html; charset=ISO-8859-1" 
pageEncoding="ISO-8859-1"%> 
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> 
<html> 
<head> 
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> 
<title>Welcome Page</title> 
</head> 
<body> 
Welcome to Spring MVC 
</body> 
</html>

刪除'ControllerClassNameHandlerMapping'並添加''。 –

我添加了，但仍然不起作用。我在上面的問題中做了修改。 –

刪除歡迎文件列表，並像這樣更改映射@RequestMapping（value = {「/」，「/ hello」}） –

改變你的SpringMVC-servlet.xml文件把下面的代碼

 <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 
      <property name="prefix" value="/WEB-INF/jsp/"/> 
      <property name="suffix" value=".jsp"/> 
     </bean> 
    <context:component-scan base-package="org.spring"/> 
    <mvc:annotation-driven/> 


    @RequestMapping(value = {"/","/index","/hello"}) 
    public ModelAndView helloworld() { 
    ModelAndView model = new ModelAndView("welcome"); 
    return model; 
}
