这是我的错误：

这是我的界面： 通常xml和界面中的ID是相同的。
package doh.ro4b.intranet4b.persistence;
import java.util.List;
import doh.ro4b.intranet4b.domain.Ictinv;
public interface IctinvMapper {
public List<Ictinv> getIctinvList (Ictinv ictinv);
public int getTotalRowCountIctinv ();
public void addIctinv (Ictinv ictinv);
public Ictinv viewIctinv (int ictinv_seqno);
public int modifyIctinv (Ictinv ictinv);
public int deleteIctinv (int ictinv_seqno);
}
这是我的xml映射器：
<?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">
<mapper namespace="doh.ro4b.intranet4b.persistence.IctinvMapper">
<select id="getIctinvList" parameterType="Ictinv" resultType="Ictinv">
SELECT *
FROM tbl_ictinv
ORDER BY ictinv_seqno ASC
<!-- LIMIT #{startRowNo}, #{rowCountPerPage} -->
</select>
<select id="getTotalRowCountIctinv" parameterType="Ictinv"
resultType="int">
SELECT COUNT(ictinv_seqno)
FROM tbl_ictinv
</select>
如果我删除插入和更新标签，则不会出现错误 请注意，我没有使用相同的ID名称

注意：如果删除插入和更新标签，则没有错误。最好的解决方案是什么？
