整合的之前需要从官网上下载spring完整的jar包,我下载的是spring-framework-3.2.2.RELEASE。整合步骤如下:
1、在eclipse中新建一个web项目,将下载的spring的jar包拷入lib目录下,但是spring启动的时候依赖一个commons-logging-1.1.jar的jar包,你需要额外的下载。
2、编写web.xml,配置spring的分发器和spring配置文件的位置。具体内容如下:
<servlet>
        <servlet-name>spring_springMVC_IntegrationDemo</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:config/spring.xml</param-value>
        </init-param>
    </servlet>

    <servlet-mapping>
        <servlet-name>spring_springMVC_IntegrationDemo</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

3、在src下新建config包名,然后新建spring.xml文件。具体内容如下:

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

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"
    xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    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.xsd  
      http://www.springframework.org/schema/mvc  
      http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
    <!-- 开启注解 -->
    <mvc:annotation-driven />

    <!-- 注解扫描范围 -->
    <context:component-scan base-package="com.evan"></context:component-scan>

    <!-- 视图解析器 -->
    <bean id="viewResolver"
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/"></property>
        <property name="suffix" value=".jsp"></property>
    </bean>

</beans>

4、新建类名UserAction,具体内容如下:

package com.evan.action;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import com.evan.service.IUserService;

@Controller
@RequestMapping("/user")
public class UserAction {

    @Autowired
    IUserService userService;

    @RequestMapping("/add")
    public String addUser() {
        System.out.println(userService.addUser());
        return "addUserView";
    }
}

5、新建IUserService接口,接口内容如下:

package com.evan.service;

public interface IUserService {

    public int addUser();
}

6、新建UserServiceImpl类名,具体内容如下:

package com.evan.service.impl;

import org.springframework.stereotype.Service;

import com.evan.service.IUserService;

@Service
public class UserServiceImpl implements IUserService {

    @Override
    public int addUser() {
        System.out.println("添加用户成功");
        return 1;
    }

}

7、在webContent目录下新建addUserView.jsp,内容是一句提示:
spring和springMVC整合成功!!

8、将项目添加到tomcat运行目录,访问http://localhost:8080/Spring_SpringMVC_IntegrationDemo/user/add 能正常访问,表示整合成功。
9、整个项目源码目录结构截图如下:
