java - itext，飞碟:xhtml到pdf ClassCastException

public void createPDF() {
    FacesContext facesContext = FacesContext.getCurrentInstance();
    ExternalContext externalContext = facesContext.getExternalContext();
    HttpSession session = (HttpSession) externalContext.getSession(true);
    String url = "http://localhost:8080/comap/pages/admin/student.xhtml";
    try {
        ITextRenderer renderer = new ITextRenderer();
        renderer.setDocument(url);
        renderer.layout();
        HttpServletResponse response = (HttpServletResponse) externalContext.getResponse();
        response.reset();
        response.setContentType("application/pdf");
        response.setHeader("Content-Disposition","C://user//first.pdf");
        java.io.OutputStream browserStream = response.getOutputStream();
        renderer.createPDF(browserStream);
        browserStream.close();
        session.invalidate();
    } catch (Exception ex) {
    ex.printStackTrace();
    }

    facesContext.responseComplete();
}

这是个例外。


  java.lang.ClassCastException：org.xhtmlrenderer.render.BlockBox无法转换为org.xhtmlrenderer.newtable.TableBox

最佳答案

此commit已解决此问题。您可以download the Class并将其放置在src目录中，这样就不必重新构建jar。
