作为一个想做架构师的程序员，必须是一个优秀的程序员，在引入某一个框架的时候，必须要研究源码，将新的开源框架的风险变为可控性。

1.Spring结合Mybatis最常用的配置。

< bean id= "testdataSource"

class= "org.springframework.jdbc.datasource.DriverManagerDataSource" >

< property name= "driverClassName" value ="oracle.jdbc.driver.OracleDriver" />

<!-- <property name=" url" value="jdbc:oracle:thin:@127.0.0.1:1521:orcl"

/> -->

< property name= "url" value ="jdbc:oracle:thin:@192.168.137.101:1521:ora92" />

< property name= "username" value = "sale" />

< property name= "password" value = "sale" />

</ bean>

< bean id= "sqlSessionFactory" class ="org.mybatis.spring.SqlSessionFactoryBean" >

< property name= "dataSource" ref = "testdataSource" />

< property name= "mapperLocations" >

< list>

< value> classpath:com/etrading /mapping/**/*Mapper.xml</ value >

</ list>

</ property>

<!-- <property name="typeAliasesPackage" value="com.nicchagil.mybatis3spring3intg.bean"

/> -->

</ bean>

< bean class= "org.mybatis.spring.mapper.MapperScannerConfigurer" >

< property name= "basePackage"

value= "com/etrading/mapping/common;com/etrading/mapping/account" />

< property name= "sqlSessionFactoryBeanName" value= "sqlSessionFactory" />

</ bean>

1）Spring为了整合Mybatis，专门封装了一个jar包（mybatis-spring-1.2.3.jar）,其中MapperScannerConfigurer封装了自动扫描全局路径下的Mapper

2）MapperScannerConfigurer源码分析

孜孜不倦、厚积薄发。
