關於classpath*:/其實無所謂，至少在個人目錄結構裏無所謂，用classpath:/或者不寫均可以找到的。既然我用這個跑起來了，其餘的我就不寫了。

jdbc.properties
Properties代碼
1.jdbc.url=jdbc:mysql://localhost:3306/qdclmart?useUnicode=true&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&characterEncoding=UTF-8
jdbc.driver=com.mysql.jdbc.Driver
jdbc.username=root
jdbc.password=root
裏面的dataSource就不說了，簡單說一下
①、sqlSessionFactory：用來進行數據庫操做的類，並且好玩的是雖然你配了org.mybatis.spring.SqlSessionFactoryBean，可是測試的時候你用getBean("sqlSessionFactory")獲得的確是mybatis的這個類： org.apache.ibatis.session.SqlSessionFactory，緣由是org.mybatis.spring.SqlSessionFactoryBean.getObject返回的類型給改變了。具體爲什麼我也不知道。你們能夠測試一下，強轉就拋錯誤了。
②、
Java代碼
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>
這段配置是我比較喜歡滴，由於他自動掃描了全部的XxxxMapper.java，這樣就不用一個一個手動配置Mpper的映射了，只要Mapper接口類和Mapper映射文件對應起來就能夠了。詳細的你們能夠到google mybatis項目網址看一下那個文檔，中文滴。
③、
Java代碼
1.<!-- 激活annotation功能 -->
2. <context:annotation-config />
3. <!-- 激活annotation功能 -->
4. <context:spring-configured/>
5. <!-- 掃描指定package下全部帶有如@controller,@services ,@resource,並把所註釋的註冊爲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/>
<!-- 掃描指定package下全部帶有如@controller,@services ,@resource,並把所註釋的註冊爲Spring Beans -->
<context:component-scan base-package="com.qdcl.mart.business.service" />
以上3句不解釋了啊，就是註解式管理bean，有的大神不推薦，我我的仍是喜歡，由於對大量的配置文件有些抵觸，錯了找起來比較麻煩。懶嘛。 context:component-scan儘管他是遞歸方式掃描，我仍是建議你們base-package具體一些，你懂得。
3：mart-servlet.xml
Xml代碼
1.<?xml version="1.0" encoding="UTF-8" ?>
2.<beans xmlns="http://www.springframework.org/schema/beans"
3. xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

7. xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
8. http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd
9. http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd"
10. >
11. <!-- 只能用於springMVC,用於配置springMVC的註解驅動 -->
12. <mvc:annotation-driven />
13. <!-- Spring mvc視圖解析器 -->
14. <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
15. <property name="prefix" value="/WEB-INF/view/" />
16. <property name="suffix" value=".jsp" />
17. </bean>
18. <context:component-scan base-package="com.qdcl.mart.business.web" />
19.
20.</beans>
<?xml version="1.0" encoding="UTF-8" ?>
<beans xmlns="http://www.springframework.org/schema/beans"

<!-- 只能用於springMVC,用於配置springMVC的註解驅動 -->
<mvc:annotation-driven />
<!-- Spring mvc視圖解析器 -->
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/view/" />
<property name="suffix" value=".jsp" />
</bean>
<context:component-scan base-package="com.qdcl.mart.business.web" />
</beans>
只說一句，一開始沒加<context:component-scan base-package="com.qdcl.mart.business.web" />這一句，結局就是我在Controller裏面寫RequestMapping(xxxx)的時候是找不到的，我弄了一上午，而且發誓再找不到緣由就跳樓的，還好吃飯前找出緣由。要不要麼是死人，要麼是女人了。呵呵。
四、mybatis-config.xml
Xml代碼
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. <!-- 基礎設置 -->
5. <settings>
6. <!-- changes from the defaults -->
7. <setting name="lazyLoadingEnabled" value="false" />
8. </settings>
9. <!-- 別名定義 -->
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>
<!-- 基礎設置 -->
<settings>
<!-- changes from the defaults -->
<setting name="lazyLoadingEnabled" value="false" />
</settings>
<!-- 別名定義 -->
<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，就是最後這個mappers的resource配置，當時手賤，寫成/mapper/ProductionMapper.xml,那叫一個悲劇，一直沒找到，這就是不仔細看文檔的下場。
五、XxxMapper.xml(ProductionMapper.xml)
Xml代碼
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">
4.
5.<mapper namespace="com.qdcl.mart.business.persistence.ProductionMapper">
6.
7. <!-- 檢索 -->
8. <select id="selectProductionByName" parameterType="java.lang.String" resultType="production">
9. <!-- 檢索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">
16. insert into production values (#{productionid},#{productionname},#{price},#{detail});
17. </insert>
18. <!-- 更新 -->
19. <update id="updateProduction" parameterType="production">
20. update production set productionname = #{productionname},
21. price = #{price},
22. detail = #{detail}
23. </update>
24. <!-- 刪除 -->
25. <delete id="deleteProduction" parameterType="java.lang.String">
26. delete from production where productionid = #{value}
27. </delete>
28.</mapper>
