我想导出为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?

修改

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)排除出口商的乐队(页眉页脚)。

iReport 中的报告设计:

Report's design in iReport

JRPdfExporter 的结果将是:

The result of generating the report in *PDF* format

两个乐队都出现在 PDF 文件

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 文件中不存在两个波段。

正如您所看到的,我仅为 JRCsvExporter 排除了两个频段(页眉页脚)。

要防止列标题重复,您可以使用以下属性:

net.sf.jasperreports.export.{format}.exclude.origin.keep.first.{suffix}.{arbitrary_name}

例如,为了避免在你编写的csv中重复列标题:

<property name="net.sf.jasperreports.export.csv.exclude.origin.keep.first.band.1" value="columnHeader"/>
