接口：

public interface AnimalDao {
    List<Animal> findAll();
}

实现类：

@Repository
public class AnimalDaoImpl implements AnimalDao {
    @Override
    public List<Animal> findAll() {
        return null;
    }
}

代理mapper:
AnimalMapper.xml:

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<!--namespace命名空间mapper方式下，必须为mapper接口的长类名-->
<mapper namespace="com.wance.dao.AnimalDao">
    <select id="findAll" resultType="com.wance.entity.Animal">
        select * from animal
    </select>
</mapper>

测试类：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:spring-config.xml")
public class TestAniamlMapper {
    @Autowired
    private AnimalDao animalDao;
    @Test
    public void test(){
        System.out.println(animalDao.findAll());
    }
}
