使用PDFBox jar文件打印PDF文件

Question

我想从java打印pdf文件。我尝试了很多方法来打印PDF但失败。最后，我在stackoverflow中找到了一个解决方案。但我尝试运行下面的代码，但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(); 
} 

当我运行代码时发生了一些问题。我在下面给出错误信息

将commons-logging jar添加到您的项目中。如果您正在使用mavenized项目，那么在pom.xml中添加它的依赖项。

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

对于maven依赖项，请在pom.xml中添加以下artifactId。

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

您也可以搜索或从以下网址最新版本下载JAR：
