在Java中打印PDF文件有多種方法,其中一種是使用Apache PDFBox庫。以下是一個簡單的示例代碼,演示如何在Java中打印PDF文件:
import org.apache.pdfbox.pdmodel.PDDocument;
import org.apache.pdfbox.printing.PDFPageable;
import javax.print.PrintService;
import javax.print.PrintServiceLookup;
import javax.print.DocPrintJob;
import javax.print.SimpleDoc;
import javax.print.DocFlavor;
import javax.print.attribute.HashPrintRequestAttributeSet;
import javax.print.attribute.PrintRequestAttributeSet;
import javax.print.attribute.standard.Copies;
public class PrintPDF {
public static void main(String[] args) {
try {
// 加載PDF文件
PDDocument document = PDDocument.load(new File("path_to_your_pdf_file.pdf"));
// 獲取默認打印服務
PrintService defaultPrintService = PrintServiceLookup.lookupDefaultPrintService();
// 創建PDF可打印對象
PDFPageable pdfPageable = new PDFPageable(document);
// 創建打印作業
DocPrintJob printJob = defaultPrintService.createPrintJob();
DocFlavor flavor = DocFlavor.SERVICE_FORMATTED.PAGEABLE;
// 設置打印屬性
PrintRequestAttributeSet attributes = new HashPrintRequestAttributeSet();
attributes.add(new Copies(1));
// 打印PDF文件
printJob.print(new SimpleDoc(pdfPageable, flavor, null), attributes);
// 關閉文檔
document.close();
System.out.println("PDF文件已成功打印。");
} catch (Exception e) {
e.printStackTrace();
}
}
}
請確保安裝了Apache PDFBox庫,并替換代碼中的"path_to_your_pdf_file.pdf"為您要打印的PDF文件的路徑。運行該代碼將打印指定的PDF文件。
