當介面引數比較多的時候，可以使用JavaBean來封裝引數，當引數比較少的情況，可以使用Map型別或者使用@Param註解

1.userMapper介面類

package com.aruisi.mybatis.mapper;

import com.aruisi.mybatis.dto.UserDTO;

public interface UserMapper {
	public UserDTO selectUserByNameAndSex(String loginName,Integer sex);
}

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"

	<select id="selectUserByNameAndSex" resultType="com.aruisi.mybatis.dto.UserDTO">
		SELECT  id,
				login_name AS loginName,
				sex,
				age,
				create_time AS createTime 
		FROM `user` WHERE login_name=#{loginName} and sex=#{sex}
	</select>
</mapper>
