只需尝试以下代码：
FacesContext fc = FacesContext.getCurrentInstance();
ExternalContext ec = fc.getExternalContext();
HttpServletRequest request = (HttpServletRequest) ec.getRequest();
try
{
ITextRenderer renderer = new ITextRenderer();
SharedContext scontext=renderer.getSharedContext();
scontext.setDotsPerPixel(14);
renderer.setDocument(url);
renderer.getFontResolver().addFont("C:\\WINDOWS\\FONTS\\ARIALUNI.TTF", BaseFont.IDENTITY_H, true);
renderer.layout();
HttpServletResponse response = (HttpServletResponse) ec.getResponse();
response.reset();
response.setContentType("application/pdf");
response.setHeader("Content-Disposition", "inline; filename=\""+ fileName + ".pdf\"");
OutputStream os = response.getOutputStream();
renderer.createPDF(os);
os.close();
}
catch(Exception e)
{
e.printStackTrace();
}
fc.responseComplete();
和
<p:commandButton value="Print" action="#{manageBean.createPDFOfSurveyResult()}" ajax="false" onclick="this.form.target='_blank'"/>
希望对大家有帮助

Mamba is a new state space model architecture showing promising performance on information-dense data such as language modeling, where previous subquadratic models fall short of Transformers. It is based on the line of progress on structured state space models, with an efficient hardware-aware design and implementation in the spirit of FlashAttention.
