 关于classpath*:/其实无所谓，至少在我的目录结构里无所谓，用classpath:/或者不写都可以找到的。既然我用这个跑起来了，其他的我就不写了。

 jdbc.properties 



Properties代码    
1.jdbc.url=jdbc:mysql://localhost:3306/qdclmart?useUnicode=true&amp;characterEncoding=UTF-8 
2.jdbc.driver=com.mysql.jdbc.Driver 
3.jdbc.username=root 
4.jdbc.password=root 
jdbc.url=jdbc:mysql://localhost:3306/qdclmart?useUnicode=true&amp;characterEncoding=UTF-8
jdbc.driver=com.mysql.jdbc.Driver
jdbc.username=root
jdbc.password=root
 里面的dataSource就不说了，简单说一下 
①、sqlSessionFactory：用来进行数据库操作的类，而且好玩的是虽然你配了org.mybatis.spring.SqlSessionFactoryBean，但是测试的时候你用getBean("sqlSessionFactory")得到的确是mybatis的这个类： org.apache.ibatis.session.SqlSessionFactory，原因是org.mybatis.spring.SqlSessionFactoryBean.getObject返回的类型给改变了。具体为何我也不知道。大家可以测试一下，强转就抛错误了。
 ②、 


Java代码    
1.<!-- scan mappers and let them be autowired --> 
2. <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> 
3. <property name="basePackage" value="com.qdcl.mart.business.persistence" /> 
4. </bean> 
<!-- scan  mappers and let them be autowired -->
	<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">       
		<property name="basePackage" value="com.qdcl.mart.business.persistence" />
	</bean>
 这段配置是我比较喜欢滴，因为他自动扫描了所有的XxxxMapper.java，这样就不用一个一个手动配置Mpper的映射了，只要Mapper接口类和Mapper映射文件对应起来就可以了。详细的大家可以到google mybatis项目网址看一下那个文档，中文滴。
 ③、 


Java代码    
1.<!-- 激活annotation功能 --> 
2. <context:annotation-config /> 
3. <!-- 激活annotation功能 --> 
4. <context:spring-configured/> 
5. <!-- 扫描指定package下所有带有如@controller,@services ,@resource,并把所注释的注册为Spring Beans --> 
6. <context:component-scan base-package="com.qdcl.mart.business.service" /> 
<!-- 激活annotation功能 -->
	<context:annotation-config />
	<!-- 激活annotation功能 -->
	<context:spring-configured/>
	<!-- 扫描指定package下所有带有如@controller,@services ,@resource,并把所注释的注册为Spring Beans -->
	<context:component-scan base-package="com.qdcl.mart.business.service" />
 以上3句不解释了啊，就是注解式管理bean，有的大神不推荐，我个人还是喜欢，因为对大量的配置文件有些抵触，错了找起来比较麻烦。懒嘛。 context:component-scan尽管他是递归方式扫描，我还是建议大家base-package具体一些，你懂得。
 3：mart-servlet.xml 



Xml代码    
1.<?xml version="1.0" encoding="UTF-8" ?> 
2.<beans xmlns="http://www.springframework.org/schema/beans"

10. >

		<property name="suffix" value=".jsp" />
	</bean>	
	<context:component-scan base-package="com.qdcl.mart.business.web" />

</beans>
 只说一句，一开始没加<context:component-scan base-package="com.qdcl.mart.business.web" />这一句，结局就是我在Controller里面写RequestMapping(xxxx)的时候是找不到的，我弄了一上午，并且发誓再找不到原因就跳楼的，还好吃饭前找出原因。要不要么是死人，要么是女人了。呵呵。
 4、mybatis-config.xml 



Xml代码    
1.<?xml version="1.0" encoding="UTF-8"?> 
2.<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> 
3.<configuration> 
4. <!-- 基础设置 --> 
5. <settings> 
6. <!-- changes from the defaults --> 
7. <setting name="lazyLoadingEnabled" value="false" /> 
8. </settings> 
9. <!-- 别名定义 --> 
10. <typeAliases> 
11. <typeAlias alias="production" type="com.qdcl.mart.business.domain.Production" /> 
12. </typeAliases> 
13. <!-- SQL映射文件 --> 
14. <mappers> 
15. <mapper resource="mapper/ProductionMapper.xml" /> 
16. </mappers> 
17.</configuration> 
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
	<!-- 基础设置 -->
	<settings>
		<!-- changes from the defaults -->
		<setting name="lazyLoadingEnabled" value="false" />
	</settings>
	<!-- 别名定义 -->
	<typeAliases>
		<typeAlias alias="production" type="com.qdcl.mart.business.domain.Production" />
	</typeAliases>
	<!-- SQL映射文件 -->
	<mappers>
		<mapper resource="mapper/ProductionMapper.xml" />
	</mappers>
</configuration>

 也是一句，就是最后这个mappers的resource配置，当时手贱，写成/mapper/ProductionMapper.xml,那叫一个悲剧，一直没找到，这就是不仔细看文档的下场。
 5、XxxMapper.xml(ProductionMapper.xml) 



Xml代码    
1.<?xml version="1.0" encoding="UTF-8"?> 
2.<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" 
3."http://mybatis.org/dtd/mybatis-3-mapper.dtd">

5.<mapper namespace="com.qdcl.mart.business.persistence.ProductionMapper"> 
6. 
7. <!-- 检索 --> 
8. <select id="selectProductionByName" parameterType="java.lang.String" resultType="production"> 
9. <!-- 检索sql文 --> 
10. SELECT productionid,productionname,price,detail FROM production 
11. where productionname = #{productionname} 
12. </select> 
13. 
14. <!-- 插入 --> 
15. <insert id="insertProduction" parameterType="production">

24. <!-- 删除 --> 
25. <delete id="deleteProduction" parameterType="java.lang.String"> 
26. delete from production where productionid = #{value} 
27. </delete> 
28.</mapper>
