[英]How to display pdf on JSF
嗨,我的代碼如下:
public StreamedContent getTempPdfFile() throws IOException {
File testPdfFile = new File("D:\\AFC150_20180819_0103.pdf");
streamedContent = new DefaultStreamedContent(new FileInputStream(testPdfFile), "application/pdf",
"AFC150_20180819_0103.pdf");
return streamedContent;
}
<h:panelGrid columns="1" cellpadding="5">
<p:media value="#{realReport.tempPdfFile}" player="pdf" width="1000px" height="300px">
<f:param name="id" />
</p:media>
</h:panelGrid>
但是PDF文件沒有顯示在頁面上。
這是我的示例,希望對您有所幫助,代碼具有內聯和附件:
void sendBackPDFToClient()
{
//File temp = File.createTempFile(fileName, ".pdf");
File testPdfFile = new File("D:\AFC150_20180819_0103.pdf");
FacesContext fc = FacesContext.getCurrentInstance();
ExternalContext ec = fc.getExternalContext();
ec.responseReset();
ec.setResponseContentType("application/pdf");
ec.setResponseContentLength((int)testPdfFile.length());
//Inline
//ec.setResponseHeader("Content-Disposition", "inline; filename=\"" + testPdfFile.getName() + "\"");
//Attach for Browser
ec.setResponseHeader("Content-Disposition", "attachment; filename=\"" + testPdfFile.getName() + "\"");
OutputStream output = ec.getResponseOutputStream();
Files.copy(testPdfFile.toPath(), output);
fc.responseComplete();
}
您是否嘗試過PrimeFaces Extensions的Document Viewer組件?
我認為它比p:media更易於使用,並提供更多功能,包括從URL,流或資源加載它的能力。 該基本示例向您展示了如何使用所有3種類型。
JAVA:
public StreamedContent getTempPdfFile() throws IOException {
File testPdfFile = Paths.get("D:\\AFC150_20180819_0103.pdf").toFile();
return new DefaultStreamedContent(new FileInputStream(testPdfFile), "application/pdf",
"AFC150_20180819_0103");
}
XHTML:
<pe:documentViewer height="500" width="1000" value="#{realReport.tempPdfFile}"/>
