在applicationContext.xml中使用<mybatis:scan />

<beans xmlns="http://www.springframework.org/schema/beans"xmlns:context="http://www.springframework.org/schema/context"xmlns:tx="http://www.springframework.org/schema/tx"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://www.springframework.org/schema/beans     http://www.springframework.org/schema/beans/spring-beans-3.0.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsdhttp://www.springframework.org/schema/txhttp://www.springframework.org/schema/tx/spring-tx-3.0.xsd">...<!-- mybatis --><bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"><property name="dataSource" ref="dataSource" /><property name="mapperLocations" value="classpath:mybatis/mapper/**/*.xml" /><property name="configLocation" value="classpath:mybatis/mybitas-config.xml" /></bean><mybatis:scan base-package="org.xyz.jblog.dao"/>...</beans>

在applicationContext.xml中使用bean标签注册MapperScannerConfigurer，即

<beans xmlns="http://www.springframework.org/schema/beans"xmlns:context="http://www.springframework.org/schema/context"xmlns:tx="http://www.springframework.org/schema/tx"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://www.springframework.org/schema/beans     http://www.springframework.org/schema/beans/spring-beans-3.0.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsdhttp://www.springframework.org/schema/txhttp://www.springframework.org/schema/tx/spring-tx-3.0.xsd">...<!-- mybatis --><bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"><property name="dataSource" ref="dataSource" /><property name="mapperLocations" value="classpath:mybatis/mapper/**/*.xml" /><property name="configLocation" value="classpath:mybatis/mybitas-config.xml" /></bean><bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"><property name="basePackage" value="org.xyz.jblog.dao" /></bean>...</beans>

如果应用是使用Java配置方式而不是XML，则在@Configuration配置类使用@MapperScan或者@MapperScans注解：

@Configuration
@MapperScan("org.xyz.jblog.dao")
public class AppConfig {@Beanpublic DataSource dataSource() {return new PooledDataSource("com.mysql.jdbc.Driver", "jdbc:mysql://localhost:3306/test", "root", "root");}@Beanpublic SqlSessionFactory sqlSessionFactory() throws Exception {SqlSessionFactoryBeansessionFactory = new SqlSessionFactoryBean();sessionFactory.setDataSource(dataSource());return sessionFactory.getObject();}
}
