impl:

    public class TestMapperImpl extends SqlSessionDaoSupport implements TestMapper {
public List<Test> selectByReg() {
return getSqlSession().selectList("selectByReg");

}

测试:

    public class SpringTest2 {
@Test
public void test1(){
ApplicationContext context = new ClassPathXmlApplicationContext("classpath:spring/applicationContext.xml");
// TestMapperImpl bean = context.getBean(TestMapperImpl.class);
TestMapper mapper = (TestMapper) context.getBean("testMapper");
List<mapper.Test> list = mapper.selectByReg();
System.out.println(list);
}
