我使用了gxt2.5,java1.7,oracle 11g,MyBatis。 我想使用jxsl上传和更新到数据库中。
excel.xsl或excel.xlsx http://i.stack.imgur.com/Bk5As.jpg

我不知道loopbreakcondition。 当listFile.b为null时我想要中断。因为,listFile.b是PK。

答案 0 :(得分:1)
尝试使用以下循环中断条件
<loopbreakcondition>
<rowcheck offset="0">
<cellcheck offset="1"/>
</rowcheck>
</loopbreakcondition>
因此,您指示检查listFile.b字段所在的B列(offset = 1)中的单元格,并在此单元格中的值为空时中断循环。
