第一步：

pom文件导入springmvc所依赖的jar 如下：

  <dependency>
   <groupId>org.springframework</groupId>
   <artifactId>spring-core</artifactId>
   <version>3.0.7.RELEASE</version>
  </dependency>
  <dependency>
   <groupId>org.springframework</groupId>
   <artifactId>spring-web</artifactId>
   <version>3.0.7.RELEASE</version>
  </dependency>
  <dependency>
   <groupId>org.springframework</groupId>
   <artifactId>spring-webmvc</artifactId>
   <version>3.0.7.RELEASE</version>
  </dependency>
  <dependency>
   <groupId>org.codehaus.jackson</groupId>
   <artifactId>jackson-mapper-asl</artifactId>
   <version>1.7.1</version>
  </dependency>

第二步：

配置web.xml 如下：

<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:com/pzx/springConfig/*.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>

第三步：

配置springMVC-servlet.xml文件如下：

<?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:p="http://www.springframework.org/schema/p"
        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-3.0.xsd
       http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
       http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
       http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd
       http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd" default-autowire="byName">


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

    <context:component-scan base-package="com.pzx.*"></context:component-scan>


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

    </beans>

第四步：

编写helloword请求处理类

package com.pzx.controller;

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

@Controller
@RequestMapping("/helloWorldController")
public class HelloWorldController {

@RequestMapping("/sayHello")
public String sayHello() {
System.out.println("HelloWorldController!!!!!!!!!!!!!!!!!!!!!!");

return "helloWorld";

}
@RequestMapping("/sayHello2")
public ModelAndView sayHello2() {
  System.out.println("HelloWorldController2!!!!!!!!!!!!!!!!!!!!!!");

  return new ModelAndView("helloWorld");

}
}

这两种接受请求并返回写法效果一样都是返回helloWorld.jsp

以上配置完后启动tomcat 浏览器输入：http://localhost:8088/TestMavenAndSpringMvc/helloWorldController/sayHello

在配置过程也遇到了一些问题现整理如下；

1:元素 "mvc:annotation-driven" 的前缀 "mvc"未绑定

解决:这是我在spring-servlet.xml文件里使用<mvc>开头的标签时，忘记引入了命名空间。在xml的beans里面加入如下代码即可

xmlns:mvc="http://www.springframework.org/schema/mvc"
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd

2: No mapping found for HTTP request with URI

原因spring没有扫描到工程的包导致找不到请求

解决: <context:component-scan base-package="com.pzx.*"></context:component-scan> 这个配置要仔细看下是否匹配

以上是自己的整理的于大家分享后续我会更新一篇springmvc 整合hibernate 和spingmvc整合mybatis的文章敬请持续关注！！
