ストーリー: 2 つのドメイン オブジェクト:
class JasperProject {
private String ...
}
class JasperProjectGroup {
private String ...
private List<JasperProject> ...
}
ジャスパーのコード:
Map<String, Object> parameters = new HashMap<String, Object>();
List<JasperProjectGroup> groups = buildGroups();
parameters.put("groups", groups);
InputStream jasperReportInputStream = ProjectStatusReportGenerator.class.getClassLoader().getResourceAsStream(
PROJECT_STATUS_JASPER_REPORT_FILENAME);
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReportInputStream, parameters,
new JREmptyDataSource());
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
JasperExportManager.exportReportToPdfStream(jasperPrint, outputStream);
return outputStream.toByteArray();
各ページにグループテーブルがあるテーブルを含むpdfレポートを作成したい(たとえば、ページ1のグループ1のテーブル、ページ2のグループ2のテーブル)。ただし、グループをパラメーターとして Jasper テンプレートに渡すと、pdf レポートのすべてのグループを含むテーブルが 1 つだけ表示されます。
jrxml の XML コード
