entity：

@Data
@AllArgsConstructor
@NoArgsConstructor
public class User {private Integer id;private String username;private String password;private String phone;private String address;
}

dao接口：

public interface UserDAO {List<User> selectAllByNameAndPhone(String username,String phone);List<User> selectAllByDTO(UserDTO userDTO);List<User> selectByMap(Map<String,String> map);User selectById(Integer id);List<User> selectByName(String username);List<User> orderByColumn(String column);}

mapper.xml映射文件：

<!--    <select id="selectAllByNameAndPhone" resultType="user">-->
<!--        <include refid="baseQuery"/> where username like concat('%',#{username},'%') and phone like concat('%',#{phone},'%')-->
<!--    </select>--><select id="selectAllByNameAndPhone" resultType="user"><include refid="baseQuery"/> where username like concat('%',#{arg0},'%') and phone like concat('%',#{arg1},'%')</select><!--    <select id="selectAllByNameAndPhone" resultType="user">-->
<!--        <include refid="baseQuery"/> where username like concat('%',#{param1},'%') and phone like concat('%',#{param2},'%')-->
