SpringBoot利⽤JasperReport⽣成PDF
JasperReport是⼀个强⼤、灵活的报表⽣成⼯具，能够展⽰丰富的页⾯内容，并将之转换成PDF，HTML，或者XML格式。该库完全由Java写成，可以⽤于在各种Java应⽤程
⾸先我们需要在JasperSoft Studio创建⼀个我们需要⽣成的PDF模板，将模板放⼊我们的SpringBoot⼯程下。 下⾯是利⽤PDF模板⽣成binary⽂件的共通⽅法
private byte[] EmInfoReporting(HashMap<String, Object> param, List<EmInfo> data) {
InputStream input;
try {
input = new Resource("classpath:report/eminfo.jrxml").getFile());
JRBeanCollectionDataSource dataSource = new JRBeanCollectionDataSource(data);
JasperReport jasperReport = JasperCompileManagerpileReport(input);
JasperPrint jasperPrint;
jasperPrint = JasperFillManager.fillReport(jasperReport, param, dataSource);
return portReportToPdf(jasperPrint);
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (JRException e) {
e.printStackTrace();
} catch (Exception e) {nrb
e.printStackTrace();
}
return null;
}
<form id="exportPDF" th:method="POST" th:action="@{/nms/report}" target='_blank'>
<input type="text" id="id" name="id" th:value="${infoid}"/>
</form>
<a class="btn btn-link" href="javascript:exportPDF();">PDF⽣成</a>

function exportPDF(){
var action = $("#exportPDF").attr("action");
if(action.substring(action.length - 4, action.length) !== ".pdf"){
var curDate = new Date();
var curMonth = Month()+1;
var Current = FullYear() + "-" + (curMonth < 10 ? "0" + curMonth : curMonth) + "-" + (Date() < 10 ? "0" + Date() : Date()) + " " + (Hours() < 10 ? "0" + Hours() : $("#exportPDF").attr("action", action + "/PDF_" + place(/-/g, "").replace(/:/g, "").replace(" ", "") + ".pdf");
}
$("#exportPDF").submit();
}
Server端接收到请求后调⽤⽣成binary⽂件的共通⽅法，利⽤HttpServletResponse类输出PDF
@PostMapping("report/{filename}")
public String emInfoPdfViewPost(@RequestParam("id") int id,@PathVariable String filename,HttpServletResponse response) {
HashMap<String,Object> params=new HashMap<String,Object>();
params.put("Client_name","makoto yagi");
List<EmInfo> datasource=new ArrayList<EmInfo>();
EmInfo eminfo=emInfoService.findOne(id);
datasource.add(eminfo);
血液回收params.put("eminfo",eminfo); byte[] output=EmInfoReporting(params,datasource);
response.setContentType("application/pdf");
response.setHeader("Content-Disposition", "inline;filename=" + filename);//inline 在线预览；attachment 下载 杨汇泉response.setContentLength(output.length);
OutputStream os=null;
try {
OutputStream();
os.write(output);
os.flush();
os.close();
}catch(IOException e) {孙志刚事件
}
return null;
}
