jasper-reports - 如何在不重复页眉和页脚的情况下导出到 CSV？

Question

我想导出到 CSV，页眉和页脚只显示一次

The current output:
Name   Address Hobby
AAA    US      XXXXX
BBB    UK      XXXXX
(Footer)
Name   Address Hobby
CCC    ID      XXXXX
DDD    CC      XXXXX
(Footer)
Name   Address Hobby
EEE    SA      XXXXX
FFF    ZM      XXXXX
(Footer)

The desired output:
Name   Address Hobby
AAA    US      XXXXX
BBB    UK      XXXXX
CCC    ID      XXXXX
DDD    CC      XXXXX
EEE    SA      XXXXX
FFF    ZM      XXXXX
(Footer)

那么如何让页眉和页脚只显示一次呢？

您可以使用 net.sf.jasperreports.export.{format}.exclude.origin.{suffix}.{arbitrary_name} (有关详细信息，请参阅 http://jasperreports.sourceforge.net/config.reference.html 页面)属性用于排除带区(​​在您的情况下为页眉和页脚)对于导出商。

sample :

输入数据，csv文件(数据源):

AAA,US,XXXXX
BBB,UK,XXXXX
CCC,ID,XXXXX
DDD,CC,XXXXX
EEE,SA,XXXXX
FFF,ZM,XXXXX

iReport 中的报表设计:



JRpdfExporter 的结果将是:



两个波段都存在于 PDF 文件中

JRCsvExporter 的结果将是(输出 csv 文件):

AAA,US,XXXXX
BBB,UK,XXXXX
CCC,ID,XXXXX
DDD,CC,XXXXX
EEE,SA,XXXXX
FFF,ZM,XXXXX

CSV 文件中不存在这两个波段。

如您所见，我仅针对 JRCsvExporter 排除了两个波段(页眉和页脚)。
