配置SpringMVC项目

1、首先新建JavaProject项目，并转为maven项目

pom.xml文件如下

<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/xsd/maven-4.0.0.xsd">  <modelVersion>4.0.0</modelVersion>  <groupId>mySpring</groupId>  <artifactId>mySpring</artifactId>  <version>0.0.1-SNAPSHOT</version>  <build>    <plugins>      <plugin>        <artifactId>maven-compiler-plugin</artifactId>        <version>3.3</version>        <configuration>          <source>1.6</source>          <target>1.6</target>        </configuration>      </plugin>    </plugins>  </build></project>

2、在pom文件中加入spring-web，spring-webmvc，servlet-api依赖

<dependencies>     <dependency>     <groupId>org.springframework</groupId>     <artifactId>spring-web</artifactId>     <version>${springVersion}</version>    </dependency>    <dependency>     <groupId>org.springframework</groupId>     <artifactId>spring-webmvc</artifactId>     <version>${springVersion}</version>    </dependency>    <dependency>        <groupId>javax.servlet</groupId>        <artifactId>servlet-api</artifactId>        <version>2.5</version>        <scope>provided</scope>    </dependency>  </dependencies>  <properties>     <springVersion>3.2.5.RELEASE</springVersion>  </properties>

3、创建web.xml文件并配置org.springframework.web.servlet.DispatcherServlet，所有请求均叫经由DispatcherServlet处理及转发。

<web-app 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_3_0.xsd"      version="3.0">     <!-- 配置SpringMVC -->    <servlet>        <servlet-name>spring-mvc</servlet-name>        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>        <init-param>               <param-name>contextConfigLocation</param-name>              <param-value>                   /WEB-INF/spring-mvc-servlet.xml            </param-value>          </init-param>        <load-on-startup>1</load-on-startup>    </servlet>    <servlet-mapping>        <servlet-name>spring-mvc</servlet-name>        <url-pattern>/</url-pattern>    </servlet-mapping></web-app>

   spring-mvc-servlet.xml文件是Spring容器的配置文件，默认为<servlet-name>-servlet.xml，可以添加启动参数contextConfigLocation重命名（此处未重新命名，仍叫做spring-mvc-servlet.xml ）。其内容如下

<beans xmlns="http://www.springframework.org/schema/beans"    xmlns:context="http://www.springframework.org/schema/context"    xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    xmlns:tx="http://www.springframework.org/schema/tx"    xmlns:aop="http://www.springframework.org/schema/aop"    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        http://www.springframework.org/schema/mvc        http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd        http://www.springframework.org/schema/aop        http://www.springframework.org/schema/aop/spring-aop-3.1.xsd">   <!--  在xml配置了这个标签后，spring可以自动去扫描base-pack下面或者子包下面的Java文件，如果扫描到有@Component @Controller@Service等这些注解的类，则把这些类注册为bean -->    <context:component-scan base-package="com.xtli"/></beans>

   4、创建controller

package com.xtli.controller;import javax.servlet.http.HttpServletRequest;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.servlet.ModelAndView;@Controllerpublic class Hello{      private static final String HELLO = "/xtli/hello/hello.jsp";      @RequestMapping(value="/hello")     public ModelAndView helloWorld(HttpServletRequest request){           ModelAndView mv = new ModelAndView(HELLO);           mv.addObject("message","Hello World!!!");         return mv;     }}

创建hello.jsp文件

    5、在浏览器中输入地址http://localhost:8045/mySpring/hello，显示

配置完成。
