在zk中运用ireport导出word文档！

在已经做好ireport的模板的前提下：

1. 首先获得zk中的session

static HttpSession session = (HttpSession) Sessions.getCurrent()
.getNativeSession();

2.定义Media

private Media media;

3.加载Jasper，设置参数

Map map = new HashMap();

JasperReport jr;
JasperPrint jp = null;
JRAbstractExporter exporter = null;
try {
jr = (JasperReport) JRLoader.loadObject(path + "/factRecord/ireport/factstatute.jasper");//加载Jasper
jp = JasperFillManager.fillReport(jr, map, new JREmptyDataSource());
exporter = new JRRtfExporter();//这里可以选择其他文件格式
ByteArrayOutputStream arrayOutputStream = new ByteArrayOutputStream();
exporter.setParameter(JRExporterParameter.JASPER_PRINT, jp);
exporter.setParameter(JRExporterParameter.OUTPUT_STREAM,
arrayOutputStream);
exporter.setParameter(JRHtmlExporterParameter.IS_OUTPUT_IMAGES_TO_DIR,Boolean.TRUE);
exporter.exportReport();
arrayOutputStream.close();
media = new AMedia("fact_statute.doc", "rtf", "application/rtf",
arrayOutputStream.toByteArray());
} catch (Exception e) {
e.printStackTrace();
}
return media;

4.用zk组件下载

Filedownload.save(media);
