**上回写过搭建SSH框架(Struts 2 + Hibernate + Spring)的教程,这里做一篇SpringMVC + Hibernate + Spring 的教程,由于SpringMVC是Spring的一个web子项目,所以在MyEclipse中有很好的集成环境可以搭建.搭建步骤见下**

1.新建一个web工程

![Center][]

2.集成Sping框架(其实内置Spring + SpringMVC)

所需要的包是**AOP**,**Core,Persistence Core**(支持hibernate),**Misc**,**Web** 共5个包，对应的勾选图中5项

![Center 1][]

![Center 2][]

3.这样就已经集成了SpringMVC(Spring的web展现层)+Spring,接下来需要在集成数据持久层,这里我们选择全自动化,功能强大的Hibernate框架

![Center 3][]

接下来的步骤就和搭建SSH(Struts 2 + Hibernate + Spring)的步骤一样了,不造车轮.

![Center 5][]

![Center 6][]

![Center 7][]

![Center 8][]

4.这样就集成好了该三大框架的开发环境,但SpringMVC还需要配置一些xml,才能正常使用.

在web.xml中配置如下:

<?xml version="1.0" encoding="UTF-8"?>
    <web-app version="3.0" 
    	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">
      <display-name></display-name>	
      <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
      </welcome-file-list>
      
      <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:springmvc-servlet.xml</param-value>
          </init-param>
      </servlet>
      
      <servlet-mapping>
         <servlet-name>springmvc</servlet-name>
         <url-pattern>/</url-pattern>
      </servlet-mapping>
      
      <listener>
         <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
      </listener>
      <context-param>
          <param-name>contextConfigLocation</param-name>
          <param-value>classpath:springmvc-servlet.xml</param-value>
      </context-param>
    </web-app>

接着在src目录下创建springmvc-servlet.xml

<?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/mvc                
           http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd                
           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">       
                 
          <context:component-scan base-package="com.sunline.controller" />       
                 
           <mvc:annotation-driven />      
       
          <bean id="internalResourceViewResolver" 
                class="org.springframework.web.servlet.view.InternalResourceViewResolver">              
            <property name="prefix" value="/jsp/" />              
            <property name="suffix" value=".jsp" />       
          </bean>
    </beans>

在/WebRoot目录下创建一个jsp文件,用于存放要展示的视图层页面.接着在new一个index.jsp

在src下建一个com.sunline.controller包,再新建一个TestController,用于跳转视图的控制,相当于Struts 2 的Action类

package com.sunline.controller;
    
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    
    @Controller
    public class TestController {
    
    	@RequestMapping(value="home")
    	public String index(){
    		return "/main";
    	}
    }

再在jsp文件夹下新建一个main.jsp

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
    <%
    String path = request.getContextPath();
    String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
    %>
    
    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
    <html>
      <head>
        <base href="<%=basePath%>">
        
        <title>My JSP 'main.jsp' starting page</title>
        
    	<meta http-equiv="pragma" content="no-cache">
    	<meta http-equiv="cache-control" content="no-cache">
    	<meta http-equiv="expires" content="0">    
    	<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
    	<meta http-equiv="description" content="This is my page">
    	
    
      </head>
      
      <body>
        <b>欢迎来到主页</b>. <br>
      </body>
    </html>

修改建项目时,自动产生的index.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
    <%
    String path = request.getContextPath();
    String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
    %>
    
    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
    <html>
      <head>
        <base href="<%=basePath%>">
        
        <title>My JSP 'index.jsp' starting page</title>
    	<meta http-equiv="pragma" content="no-cache">
    	<meta http-equiv="cache-control" content="no-cache">
    	<meta http-equiv="expires" content="0">    
    	<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
    	<meta http-equiv="description" content="This is my page">
    	
      </head>
      
      <body>
        This is my JSP page. <br>
        <a href="${pageContext.request.contextPath }/home">点击到主页</a>
      </body>
    </html>

一切工作做好之后的工程目录是这样的

大功告成,接下来就可以在里面尽情地造车轮了!
