我使用java中的itext pdf创建了一个带有数据库值的pdf。现在我需要在我的angularjs中打开该ModelAndView。
这是我的代码
Controller.js
$scope.strPdf=function strPdf(id){
$http.get(urlBase+"/stockTransferPdf/"+id).success(function(data){
alert("success");
})
}
controller.java
@RequestMapping(value = "/stockTransferPdf/{id}", method = RequestMethod.GET)
public ModelAndView stockTranferPdfView(@PathVariable int id,HttpServletRequest request,HttpServletResponse response) {
StockTransferRequest str=inventoryService.getStockTransferRequest(id);
ModelAndView m = new ModelAndView("stockTransferPdfView");
m.getModelMap().addAttribute("stockTransfer",str);
return m;
}

使用上面的代码我可以创建一个包含数据库内容的 pdf 文件,但我需要显示该 pdf 文件。我不知道该怎么做。
过去两天我对此感到震惊。任何人都可以帮助我实现我的需求吗?
最佳答案
在 Spring Controller 中,你的方法应该如下所示。
@RequestMapping(value = "createPdf", method = RequestMethod.GET, produces = "application/pdf")
public ResponseEntity<byte[]> createPdf(HttpServletResponse response) {
response.setContentType("application/pdf");
byte[] contents = // populate pdf data
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.parseMediaType("application/pdf"));
headers.set("Content-Disposition", "inline");
return new ResponseEntity<>(contents, headers, HttpStatus.OK);
}
然后在 Angular JS 中。
$http({
url: "url",
method: 'GET',
responseType: 'arraybuffer'
})
.then(({ data }) => {
var file = new Blob([data], { type: 'application/pdf' });
var fileURL = URL.createObjectURL(file);
$window.open(fileURL);
})
