使用 PDFBox jar 文件打印 PDF 文件

Question

我想从 java 打印一个 pdf 文件。我尝试了很多方法来打印 pdf，但都失败了。最后，我在stackoverflow中找到了解决方案。但是我尝试运行下面的代码但是编译代码时出现问题

PrinterJob job = PrinterJob.getPrinterJob();
PageFormat pf = job.defaultPage();
Paper paper = new Paper();
paper.setSize(612.0, 832.0);
double margin = 10;
paper.setImageableArea(margin, margin, paper.getWidth() - margin, paper.getHeight() - margin);
pf.setPaper(paper);
pf.setOrientation(PageFormat.LANDSCAPE);

// PDFBox

PDDocument doc=PDDocument.load(file);
job.setPageable(new PDPageable(doc, job));

job.setJobName("funciona?");

if(job.printDialog()){
    job.print();
}

运行代码时出现了一些问题。我在下面给出错误消息

将 commons-logging jar 添加到您的项目中。如果您使用的是 mavenized 项目，请在 pom.xml 中添加其依赖项。

如果您必须手动添加 commons-logging jar，请确保它在类路径中可用。

对于 maven 依赖，在 pom.xml 中添加以下 artifactId。

<dependency>
    <groupId>commons-logging</groupId>
    <artifactId>commons-logging</artifactId>
    <version>1.1.1</version>
</dependency>

您也可以从以下 URL 搜索或下载最新版本的 jar：
