搭建Spring MVC 4开发环境八步走

Spring MVC作为SpringFrameWork的产品，自诞生之日，就受到广泛开发者的关注，如今Spring MVC在Java中的发展可谓是蒸蒸日上，如今如果再有开发者说，不了解Spring MVC，或许就被人笑掉大牙。煽情的话就不说了，先告诉大家如何搭建Spring MVC开发环境。

  

    （一）工作环境准备：

        JDK 1.7

        Eclipse Kepler

        Apache Tomcat 8.0

 

    （二）在Eclipse中新建Maven工程，在Archetype类型中，选择“maven-archetype-webapp”。

 

 

 

    （三）配置pom.xml。

 

< project  xmlns = "http://maven.apache.org/POM/4.0.0"  xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation = "http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd" >
  < modelVersion >4.0.0</ modelVersion >
  < groupId >com.favccxx.favsoft</ groupId >
  < artifactId >favspringmvcrestful</ artifactId >
  < packaging >war</ packaging >
  < version >0.0.1-SNAPSHOT</ version >
  < name >favspringmvcrestful Maven Webapp</ name >
  < url >http://maven.apache.org</ url >

   < properties >
      < spring.version >4.1.1.RELEASE</ spring.version >
  </ properties >

  < dependencies >
    < dependency >
      < groupId >junit</ groupId >
      < artifactId >junit</ artifactId >
      < version >3.8.1</ version >
      < scope >test</ scope >
    </ dependency >

    < dependency >
        < groupId >org.springframework</ groupId >
        < artifactId >spring-core</ artifactId >
        < version >${spring.version}</ version >
    </ dependency >
    < dependency >
        < groupId >org.springframework</ groupId >
        < artifactId >spring-webmvc</ artifactId >
        < version >${spring.version}</ version >
    </ dependency >
    < dependency >
        < groupId >org.springframework</ groupId >
        < artifactId >spring-beans</ artifactId >
        < version >${spring.version}</ version >
    </ dependency >
    < dependency >
        < groupId >org.springframework</ groupId >
        < artifactId >spring-context</ artifactId >
        < version >${spring.version}</ version >
    </ dependency >

    < dependency >
        < groupId >jstl</ groupId >
        < artifactId >jstl</ artifactId >
        < version >1.2</ version >
    </ dependency >
    < dependency >
        < groupId >taglibs</ groupId >
        < artifactId >standard</ artifactId >
        < version >1.1.2</ version >
    </ dependency >

  </ dependencies >
  < build >
    < finalName >favspringmvcrestful</ finalName >
  </ build >
</ project >

 

    （四）在WEB-INF/web.xml，配置Spring MVC转发。

 

<? xml  version = "1.0"  encoding = "UTF-8" ?>
< web-app  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 >favspringmvcrestful</ display-name >

    < filter >
        < filter-name >encodingFilter</ filter-name >
        < filter-class >org.springframework.web.filter.CharacterEncodingFilter</ filter-class >
        < init-param >
            < param-name >encoding</ param-name >
            < param-value >UTF-8</ param-value >
        </ init-param >
        < init-param >
            < param-name >forceEncoding</ param-name >
            < param-value >true</ param-value >
        </ init-param >
    </ filter >
    < filter-mapping >
        < filter-name >encodingFilter</ filter-name >
        < url-pattern >/*</ url-pattern >
    </ filter-mapping >

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

    < servlet >
        < servlet-name >springMVC</ servlet-name >
        < servlet-class >org.springframework.web.servlet.DispatcherServlet</ servlet-class >
        < init-param >
            < param-name >contextConfigLocation</ param-name >
            < param-value >classpath*:spring-context.xml</ param-value >
        </ init-param >
        < load-on-startup >1</ load-on-startup >
    </ servlet >
    < servlet-mapping >
        < servlet-name >springMVC</ servlet-name >
        < url-pattern >/</ url-pattern >
    </ servlet-mapping >
</ web-app >

 

    （五）在resources目录下，创建spring-context.xml，支持注解，页面路径解析等。

 

<? 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:context = "http://www.springframework.org/schema/context"
    xmlns:mvc = "http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd
        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd">

    < context:component-scan  base-package = "com.favccxx.favsoft.favjson.controller" ></ context:component-scan >

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

    < 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/views"  />
        < property  name = "suffix"  value = ".jsp"  />
    </ bean >
</ beans >

 

    （六）新建HelloController类，使用注解完成Spring MVC类的调用。

 

package  com.favccxx.favsoft.favjson.controller;

import  java.util.HashMap;
import  java.util.Map;

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

@Controller
public  class  HelloController {

    @RequestMapping ( "/greeting" )
    public  ModelAndView greeting( @RequestParam (value= "name" , defaultValue= "World" ) String name) {
         System.out.println( "Hello "  + name);
         Map<String, Object> map =  new  HashMap<String, Object>();
         map.put( "userName" , name);
         return  new  ModelAndView( "/hello" ,map);
    }

}

 

    （七）创建/WEB-INF/views/hello.jsp，用来展现数据。

 

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<!DOCTYPE html>
< html >
< head >
< meta  http-equiv = "Content-Type"  content = "text/html; charset=UTF-8" >
< title >Hello</ title >
</ head >
< body >
    你好，${userName }
</ body >
</ html >

 

    （八）在浏览器中，输入访问的URL：http://localhost:8080/favspringmvcrestful/greeting?name=%E7%BE%8E%E5%A5%B3，运行效果如下：
