pdf application，java application pdf_從Java應用程序中即時打開PDF文件

Is there any way to have a code that opens a PDF file in Java application in a platform independant way? I mean using a batch file in Windows could do that. Is there any other way to have a platform independent code to open PDF files on the fly?

有沒有辦法讓代碼以獨立於平臺的方式在Java應用程序中打開PDF文件?我的意思是在Windows中使用批處理文件可以做到這一點。有沒有其他方法可以使用平臺無關的代碼來動態打開PDF文件?

pdf application、5 個解決方案

java動態生成pdf，我試試Desktop.open(文件),其中:

Launches the associated application to open the file.

啟動關聯的應用程序以打開文件。

import java.util。So this code should do the trick:

所以這段代碼應該可以解決問題:

if (Desktop.isDesktopSupported()) {

pdf 預覽，try {

File myFile = new File("/path/to/file.pdf");

Desktop.getDesktop().open(myFile);

javac和java，} catch (IOException ex) {

// no application registered for PDFs

}

java class？}

java.，You can use Runtime to execute and script and there are also several Java PDF viewers out there (ie Icepdf, JPedal, PDFRenderer).

您可以使用Runtime來執行和編寫腳本,還有幾個Java PDF查看器(即Icepdf,JPedal,PDFRenderer)。

Michael Meyer's solution didn't quite work for me. Specifically, a path with spaces fails with an IllegalArgumentException rather than an IOException.

Michael Meyer的解決方案並不適合我。具體來說,帶有空格的路徑失敗,帶有IllegalArgumentException而不是IOException。

Here's what works for me:

這對我有用:

if (Desktop.isDesktopSupported()) {

try {

File theUMFile = new File(usersManualPath);

Desktop.getDesktop().open(theUMFile);

}

catch (FileNotFoundException fnf){

okDialog(msg_fnf);

theConcours.GetLogger().log(Level.SEVERE, null, fnf);

theConcours.GetLogger().info(msg_fnf);

}

catch (IllegalArgumentException fnf) {

okDialog(msg_fnf);

theConcours.GetLogger().log(Level.SEVERE, null, fnf);

theConcours.GetLogger().info(msg_fnf);

}

catch (IOException ex) {

okDialog(msg_cno);

theConcours.GetLogger().log(Level.SEVERE, null, ex);

theConcours.GetLogger().info(msg_cno);

}

}

Use this to open pdf file using java

使用它來使用java打開pdf文件
