 最近在用mybatis出现上次错误，原因：

<!-- define the SqlSessionFactory -->
	<bean id="sqlSessionFactory"
		class="org.mybatis.spring.SqlSessionFactoryBean">
		<property name="dataSource" ref="dataSource" />
		<!--<property name="configLocation" value="classpath:mybatis-conf.xml" />-->
		<property name="typeAliasesPackage" value="com.XX" />
	</bean>

sqlSessionFactory上并未注册或获取到*mapper.xml里面的sql语句信息，造成这个原因无非就是：

*mapper.xml未找到或里面的sql中跟mapper接口中的方法不对应。

总之，从sqlSessionFactory或xml中入手，很容易揪出错的，而且配置这块经常容易出问题，尤其对mybatis不熟或首次集成的time！
