Java代码如何打开PDF文件呢?

实现思路:
    使用rundll32打开pdf
    使用Awt Desktop的方式打开pdf

rundll32 Windows平台解决方案

 
package com.java265.jdbc;
 
import java.io.File;
public class WindowsPlatformAppPDF {
	public static void main(String[] args) {
	  try {
		if ((new File("d:\\test.pdf")).exists()) {
			Process p = Runtime
			   .getRuntime()
			   .exec("rundll32 url.dll,FileProtocolHandler c:\\Java-Interview.pdf");
			p.waitFor();				
		} else {
			System.out.println("File is not exists");
		}
		System.out.println("Done");
  	  } catch (Exception ex) {
		ex.printStackTrace();
	  }
 
	}
}

Awt Desktop跨平台打开pdf解决方案

 
package com.java265.io;
 
import java.awt.Desktop;
import java.io.File;
 
//Cross platform solution to view a PDF file
public class AnyPlatformAppPDF {
 
	public static void main(String[] args) {
 
	  try {
 
		File pdfFile = new File("d:\\test.pdf");
		if (pdffile.exists()) {
 
			if (Desktop.isDesktopSupported()) {
				Desktop.getDesktop().open(pdfFile);
			} else {
				System.out.println("Awt Desktop is not supported!");
			}
 
		} else {
			System.out.println("File is not exists!");
		}
 
		System.out.println("Done");
 
	  } catch (Exception ex) {
		ex.printStackTrace();
	  }
 
	}
}
