首个spring mvc 测试例子搭建遇到问题记录

开发环境:jdk1.7 + tomcat7 + Eclipse Juno

首先下载spring 相关jar包

我用的是 spring-framework-3.2.1.RELEASE

下载地址:http://www.springsource.org/download/community?project=Spring%2520Framework

这里需要注意的是jar都需要手动拷入到lib下面,否则tomcat部署会出错,用buildpath 加入jar只能确保开发的时候不会出编译错误。放入lib下面,是一劳永逸的好办法。

下载相关日志包 

jcl-over-slf4j-1.6.1.jar

logback-classic-0.9.24.jar

logback-core-0.9.24.jar

slf4j-api-1.6.1.jar

下载地址:http://download.csdn.net/detail/jiujie395/5991615

在eclipse工程中建Dynamic Web project,向导式的开发,一路next,最后得到一个web工程。

这里需要注意的是:如果是Dynamic web module version 选择3.0 那么web.xml不会自动生成,需要自己创建。

在WebContent下生成一个index.jsp文件

 

<%@ page language="java" contentType="text/html; charset=UTF-8"

    pageEncoding="UTF-8"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<html>

<head>

 <title>Spring 3.0 MVC demo</title>

</head>

<body>

 <a href="hello.html">Say Hello World!</a>

</body>

</html>


在WebContent\WEB-INF目录下生成一个jsp文件夹和两个配置文件:spring-servlet.xml、web.xml

 

 

web.xml内容为

 

<?xml version="1.0" encoding="UTF-8"?>

<web-app version="2.5" 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_2_5.xsd">



    <display-name>Spring3MVC</display-name>

    <servlet>

        <servlet-name>spring</servlet-name>

        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

        <load-on-startup>1</load-on-startup>

    </servlet>



    <servlet-mapping>

        <servlet-name>spring</servlet-name>

        <url-pattern>*.html</url-pattern>

     </servlet-mapping>



     <welcome-file-list>

        <welcome-file>index.jsp</welcome-file>

    </welcome-file-list>



</web-app>


 

这里需要注意的是:servlet-name的值就是 XX-servlet.xml的命名方式。如果需要改变则需要更改

 

	<servlet>

		<servlet-name>spring</servlet-name>

		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

		<init-param>

			<param-name>contextConfigLocation</param-name>

			<param-value>classpath*:/springMVC.xml</param-value>

		</init-param>

		<load-on-startup>1</load-on-startup>

	</servlet>

	<servlet-mapping>

		<servlet-name>spring</servlet-name>

		<url-pattern>*.html</url-pattern>

	</servlet-mapping>


spring-servlet.xml内容为

 

 

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

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

 xmlns:p="http://www.springframework.org/schema/p"

 xmlns:context="http://www.springframework.org/schema/context"

 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">

  

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

  

 <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>

 

然后生成java文件HelloWorldController.java包路径为net.spring.controller

 

package net.spring.controller;



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 helloWorld() {



  String message = "Hello World, Spring 3.0!";

  System.out.println(message);

  return new ModelAndView("hello", "message", message);

 }



}


然后WEB-INF下新建jsp文件夹,然后在jsp文件夹下新建hello.jsp

 

 

<%@ page language="java" contentType="text/html; charset=UTF-8"

    pageEncoding="UTF-8"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<html>

<head>

 <title>Spring 3.0 MVC demo</title>

</head>

<body>

 	${message }

</body>

</html>

在index.jsp上点击Say Hello,就会转向 http://localhost:8080/mvc_test/hello.html页面显示Hello World, Spring 3.0!,表示工作正常。
