有没有人获得开源二维码库"来使用 ColdFusion?我需要在 ColdFusion 中生成二维码.

Has anyone gotten the "Open Source QR Code Library" to work with ColdFusion? I need to generate QR Codes in ColdFusion.

我还发现 本教程如何使用 Zxing 生成它.

I also found this tutorial on how to generate it using Zxing.

但是教程并不清楚如何配置文件，例如需要在哪个目录中...

But the tutorial is not clear on how to configure the files, e.g. what needs to be in which dir...

欢迎任何帮助和替代方法，谢谢.

推荐答案

Zxing 使用两 (2) 个 jar:core.jar 和 javase.jar.安装它们的最简单方法是将两个 jar 放在 CF 类路径中的任何位置(例如:C:ColdFusion8wwwrootweb-inflib).然后重新启动 CF 服务器.这就对了.

Zxing uses two (2) jars: core.jar and javase.jar. The easiest way to install them is to place both jars anywhere in the CF classpath (example: C:ColdFusion8wwwrootweb-inflib). Then restart the CF server. That is it.

注意:您可以自己编译 zxing jar，也可以从 blog.getRailo.com) 更新: barcode_samples.zip 文件确实包含示例 CF 代码.但它只适用于Railo.Adobe CF 不支持 createObject("java") 的额外参数.要在 Adob​​e CF 中使用代码，您需要删除额外的参数.

Note: You can either compile the zxing jars yourself or download a slightly older version from this handy entry on blog.getRailo.com) Update: The barcode_samples.zip file does contain sample CF code. But it is for Railo only. Adobe CF does not support the extra parameters for createObject("java"). To use the code in Adobe CF, you need to remove the extra parameters.

<!--- Railo syntax --->
<cfset object = createObject('java','path.to.classtoinvoke','/path/to/jar/file/on/system')>
<!--- Adobe CF --->
<cfset object = createObject('java','path.to.classtoinvoke')>

如果您无权访问类路径，则可以使用 JavaLoader.cfc 来加载两 (2) 个 zxing 罐子.只需下载该项目.它包括一些关于安装和使用的很好的例子.但如果您还有其他问题，请告诉我.

If you do not have access to the classpath, you can use the JavaLoader.cfc to load the two (2) zxing jars instead. Just download the project. It includes some pretty good examples on installation and usage. But if you have further questions, let me know.
