关于整合spring+mybatis 第三种方式-使用注解

<!-- 配置sqlSessionFactory -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"></property>
<property name="configLocation" value="classpath:com/bsss/conf/mybatis.xml"></property>
</bean> <!-- id="userloginMapper"必须与services实现类中所声明的mapper变量名保持一致 -->
<bean id="userloginMapper" class="org.mybatis.spring.mapper.MapperFactoryBean">
<property name="mapperInterface" value="com.bsss.mapper.UserloginMapper"></property>
<property name="sqlSessionFactory" ref="sqlSessionFactory"></property>
</bean>
<bean id="userServices" class="com.bsss.services.impl.UserLoginServicesImpl">
<property name="userloginMapper" ref="userloginMapper"></property>
</bean>

//Mapper接口
public interface UserloginMapper {
//org.mybatis.spring.mapper.MapperFactoryBean
@Select("select * from userlogin")
public List<Userlogin> getUserlogin();
}

public interface UserLoginServices {
public List<Userlogin> getUserLoginInfo();
}public class UserLoginServicesImpl implements UserLoginServices {
private UserloginMapper userloginMapper;//必须与beans.xml中mapper的bean id保持一致
//必须有setter方法
public void setUserloginMapper(UserloginMapper userloginMapper) {
this.userloginMapper = userloginMapper;
}
@Override
public List<Userlogin> getUserLoginInfo() {
// TODO Auto-generated method stub
return userloginMapper.getUserlogin();
}}

public class Test { public static void main(String[] args) {
ApplicationContext ac = new ClassPathXmlApplicationContext("com/bsss/conf/beans.xml");
UserLoginServices uls = (UserLoginServices)ac.getBean("userServices");
System.out.println(uls.getUserLoginInfo().size());
}}
