java - 我需要接收一个包含数组的 java 数组并在表格中生成报告

Question

我需要在参数字段上运行数据集，该字段是我从 Java 代码接收的集合。

我在尝试

<datasetRun subDataset="EstruturaOrganicaDTO" uuid="c3ec8434-efe9-4dbe-8c1a-4ba8be684bda">
    <dataSourceExpression><![CDATA[new net.sf.jasperreports.engine.data.JRMapCollectionDataSource($P{EstruturasOrganicas}.getFieldValue( $F{estruturaOrganica}))]]></dataSourceExpression>
</datasetRun>

这是我的报告，它只是说他找不到字段

我想在参数领域进行迭代。

我正在用 Java 做这个

List <EstruturaOrganicaDTO> constatacoes1 = new ArrayList<>();
EstruturaOrganicaDTO estruturaOrganicaDTO = new EstruturaOrganicaDTO();
estruturaOrganicaDTO
        .setEstruturaOrganica(
                new ArrayList<EstruturaOrganicaEntity>( ));
estruturaOrganicaDTO.getEstruturaOrganica().add(new EstruturaOrganicaEntity("abc", "123",
        "fdh", "123", "2456", false));

JRBeanCollectionDataSource beanCollectionDataSource1 = new JRBeanCollectionDataSource(constatacoes1);
final String jasperReportPath = "jasper-templates/objetivo.jrxml";

InputStream inputStreamTemplate = this.environment.resourceAsStream(jasperReportPath);

JasperReport report = JasperCompileManager.compileReport(inputStreamTemplate);

Map<String, Object> parametros = new HashMap<>();
parametros.put("EstruturasOrganicas", beanCollectionDataSource1);

JasperPrint print = JasperFillManager.fillReport(report, parametros, new JREmptyDataSource());
File pdf = File.createTempFile("temp", ".pdf");
pdf.deleteOnExit();
JasperExportManager.exportReportToPdfStream(print, new FileOutputStream(pdf));
