### 完成spring配置文件的编写 ###

<?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/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.xsd " default-lazy-init="true">  
        
        <context:component-scan base-package="com.mvc" />
        
        <mvc:annotation-driven ></mvc:annotation-driven>
        <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/"></property>
        <property name="suffix" value=".jsp"></property>
        </bean>
        
        	
        <context:property-placeholder location="classpath:jdbc.properties" />
        
     	<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
     		<property name="driverClassName" value="${jdbc.driver}"></property>
     		<property name="url" value="${jdbc.url}"></property>
     		<property name="username" value="${jdbc.username}"></property>
     		<property name="password" value="${jdbc.password}"></property>
     	</bean>
      
     	
      	<bean class="org.mybatis.spring.SqlSessionFactoryBean">
     		<property name="dataSource" ref="dataSource"></property>
     		<property name="mapperLocations" value="classpath:com/mvc/beans/*.xml"></property>
    	</bean> 
     	
     	
     	<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
     		<property name="basePackage" value="com.mvc.dao"></property>
     	</bean> 
        </beans>

### 在web.xml 加载spirng的核心控制器 ###

<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.xml</param-value>
      	</init-param>
      </servlet>
      <servlet-mapping>
      	<servlet-name>springmvc</servlet-name>
      	<url-pattern>/</url-pattern>
      </servlet-mapping>

### 编写测试代码 java ###

*  控制层

@ResponseBody
       @RequestMapping("student_list")
       public List<Student> student_list(Model model){ 
       	return pd.slist();
       }

*  数据访问层

public interface PageDao { 
    
      @Select("select * from student")
      public List<Student> slist();
    }

*  实体对象

public class Student { 
      
      String id;
      String name;
      String age;
      String sex;

### 编写测试页面 ###

<%@ page language="java" contentType="text/html; charset=UTF-8"
        pageEncoding="UTF-8"%>
    <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
    <html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <title>Insert title here</title>
    </head>
    <body>
    ${ name}
    </body>
    </html>

### 访问测试页面ok ###
