Spring MVC模型屬性值不打印

我剛開始學習spring mvc。試圖遵循世界上你好的樣本。似乎一切工作正常，除了jsp視圖無法接收控制器中設置的模型屬性值。Spring MVC模型屬性值不打印

這是一些代碼。

控制器：

package org.home.webapp.controller; 

import org.springframework.stereotype.Controller; 
import org.springframework.ui.ModelMap; 
import org.springframework.web.bind.annotation.RequestMapping; 
import org.springframework.web.bind.annotation.RequestMethod; 

@Controller 
@RequestMapping("/welcome") 
public class HelloController { 

@RequestMapping(method = RequestMethod.GET) 
public String printWelcome(ModelMap model) { 

    model.addAttribute("message", "Spring 3 MVC Hello World"); 
    return "hello"; 

} 
}

查看

<%@ 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>Hello World</title> 
</head> 
<body> 
<h1>Message : ${message}</h1> 
</body> 
</html>

的web.xml

<!DOCTYPE web-app PUBLIC

"http://java.sun.com/dtd/web-app_2_5.dtd" > 

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<listener> 
    <listener-class> 
        org.springframework.web.context.ContextLoaderListener 
      </listener-class> 
</listener> 
</web-app>

MVC-調度-servlet.xml中

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

    http://www.springframework.org/schema/context 
    http://www.springframework.org/schema/context/spring-context-3.2.xsd"> 

<context:component-scan base-package="org.home.webapp.controller" /> 

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

</beans>

嘗試使用'Model'，而不是'ModelMap'..everything看起來fine..You在'WEB-INF/pages'右'hello.jsp'？ – Anubhab 2013-03-22 09:03:08

我想代碼是從[這裏]（http://www.mkyong.com/spring3/spring-3-mvc-hello-world-example/）:) ..確保'hello.jsp'存在於正確的位置 – Anubhab 2013-03-22 09:08:21

使用Model而不是ModelMap並沒有幫助。 jsp位於正確的位置。 – 2013-03-23 05:34:47

使用<％@頁面isELIgnored =「false」％>幫助。

我們需要包含org.springframework.web.servlet.ModelAndView而不是org.springframework.web.portlet.ModelAndView;

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

@Controller 
public class HelloWorldController { 

    @RequestMapping("/hello") 
    public ModelAndView hello() 
    { 
     System.out.println("Just Test iNside"); 
     String message = "HELLO SPRING MVC HOW R U"; 
     return new ModelAndView("hello", "message", message); 
    }
