在我的休息控制器上,我添加到RequestMapping产生=&#34; application / pdf&#34;但它没有用。
@RequestMapping(value = "/gMapReports", method = RequestMethod.POST, produces = "application/pdf")
public ResponseEntity<InputStreamResource> gMapReports(@RequestBody GMapReportRequest gMapReportRequest) {
return reportService.prepareResponse(reportService.gMapReports(gMapReportRequest));
}
我的prepareResponse方法:
public ResponseEntity<InputStreamResource> prepareResponse(File reportDocument) {
FileInputStream fileInputStream = fileStreamConverter.getFileInputStream(reportDocument);
return ResponseEntity
.ok()
.contentLength(reportDocument.length())
.contentType(MediaType.APPLICATION_OCTET_STREAM)
.header("content-disposition", "filename=report")
.body(new InputStreamResource(fileInputStream));
}
答案 0 :(得分:1)
添加代码produces = {"application/pdf"}
对我有用。完整示例:
@RequestMapping(value = "/pdfFile", method = RequestMethod.POST, produces = {"application/pdf"})
@ResponseBody
public FileSystemResource getFile(@ModelAttribute PdfFile pdfFile) {
PdfFileGenerator pdfFileGenerator = new PdfFileGeneratorImpl();
File file = pdfFileGenerator.generatePdf(pdfFile);
return new FileSystemResource(file);
}
