簡單的項目在春天MVC

我想建立一個簡單的春天MVC項目。簡單的項目在春天MVC

我創建了web應用程序項目，然後添加了spring和commons-logging庫。

和此web.xml文件

<web-app id="WebApp_ID" version="2.4" 
xmlns="http://java.sun.com/xml/ns/j2ee" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee 
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> 

<display-name>Spring MVC Application</display-name> 

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

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

</web-app>

，這是的HelloWeb-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/beans  
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 
http://www.springframework.org/schema/context 
http://www.springframework.org/schema/context/spring-context-3.0.xsd"> 


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

</beans>

然後我在com.tutorialspoint包創建Java類（HelloContoller.java）

package com.tutorialspoint; 

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

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

@RequestMapping(method = RequestMethod.GET) 
public String printHello(ModelMap model) { 
    model.addAttribute("message", "Hello Spring MVC Framework!"); 

    return "hello"; 
} 

}

然後我在WEB-INF/JSP/hello.jsp中創建了JSP頁面

<%@ page contentType="text/html; charset=UTF-8" %> 
<html> 
<head> 
    <title>Hello World</title> 
</head> 
<body> 
    <h2>${message}</h2> 
</body> 
</html>

我工作的服務器GlassFish的，當我運行該項目，它給了我這個錯誤

HTTP Status 404 - Not Found 

type Status report 

messageNot Found 

descriptionThe requested resource is not available. 

GlassFish Server Open Source Edition 4.1

和GlassFish服務器給我這個警告

Warning: No mapping found for HTTP request with URI [/TestMVC4] in DispatcherServlet with name 'HelloWeb'

我看到這個問題 No mapping found for HTTP request with URI.... in DispatcherServlet with name

當我將該行添加到HelloWeb-servlet.xml中

它給了我這些錯誤

Info: visiting unvisited references 
Info: Registering WebSocket filter for url pattern /*

您的問題是，你錯過在你的配置的*註釋驅動*元素，點擊這裏http://stackoverflow.com/questions/28411049/route-mapping-wont-work/28411313#28411313 – 2015-02-10 13:03:22

我認爲你必須告訴春天在您的配置文件，所以添加以下行到你的web.xml文件：

<context-param> 
    <param-name>contextConfigLocation</param-name> 
    <param-value>/WEB-INF/HelloWeb-servlet.xml</param-value> 
</context-param> 

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

然後，你必須在春天註冊你的控制器。添加以下到您的Spring配置文件（的HelloWeb-servlet.xml中）：

<!-- Register the bean --> 
<bean class="com.tutorialspoint.HelloController" />

在你給的代碼/ TestMVC沒有定義任何where.Instead你給RequestMapping用於/你好。所以您的網址後綴改爲/ hello and try.Then你不會得到異常。

由於您尚未爲/ TestMVC提供RequestMapping路徑，因此您將收到異常。

隨着你需要把下面的註釋和他們的名字空間。

<context:component-scan base-package="XXXXXXXXXXX" /> 

    <mvc:annotation-driven />
