使用maven搭建springMVC开发环境

1、引入框架所需的包，pom.xml文件中添加如下配置：

　　　　　<dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
            <version>4.2.0.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-core</artifactId>
            <version>4.2.0.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-aop</artifactId>
            <version>4.2.0.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-tx</artifactId>
            <version>4.2.5.RELEASE</version>
        </dependency>

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-orm</artifactId>
            <version>3.2.4.RELEASE</version>
        </dependency>

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-webmvc</artifactId>
            <version>4.1.3.RELEASE</version>
        </dependency>

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-web</artifactId>
            <version>4.2.0.RELEASE</version>
        </dependency>

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-beans</artifactId>
            <version>4.2.0.RELEASE</version>
        </dependency>

2、配置springMVC转发器，web.xml文件添加配置： 

<servlet>
           <servlet-name>springMVC</servlet-name>
           <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
           <init-param>
            <param-name>contextConfigLocation</param-name>
            <!--其中<param-value>**.xml</param-value> 这里可以使用多种写法-->
            <!--1、不写,使用默认值:/WEB-INF/<servlet-name>-servlet.xml-->
            <!--2、<param-value>/WEB-INF/classes/dispatcher-servlet.xml</param-value>-->
            <!--3、<param-value>classpath*:dispatcher-servlet.xml</param-value>-->
            <!--4、多个值用逗号分隔-->
            <param-value>classpath:dispatcher-servlet.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>

3、在目录src/main/java下新建文件dispatcher-servlet.xml，该文件配置如下：

<?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:mvc="http://www.springframework.org/schema/mvc"
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
                        http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
                        http://www.springframework.org/schema/mvc
                           http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
                        http://www.springframework.org/schema/context
                        http://www.springframework.org/schema/context/spring-context-2.5.xsd">
    <!-- 自动注册RequestMappingHandlerMapping与RequestMappingHandlerAdapter两个Bean -->
      <!-- 这是Spring MVC为@Controller分发请求所必需的 -->
    <mvc:annotation-driven />
    <!-- 后缀为html的资源，直接可以访问 -->
    <mvc:resources mapping="/*.html" location="/" />
    <!--自动扫描包中的类，并创建实例  -->
    <context:component-scan base-package="cn.com.test"/>

</beans> 

4、测试，代码如下：

package cn.com.test;

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

@Controller
public class testA {

	@RequestMapping("/tst.do")
	public String show() {
		System.out.println("tst.do");
		return "/tst.html";
	}
}

访问网址http://127.0.0.1:8090/creatA/tst.do，如果正常显示，说明SpringMVC搭建成功
