问题描述
我正在使用primefaces来开发一个网络应用程序。我正在尝试在网页上显示条形码。除了QR代码外，所有编码器都显示出来。我已经读过这个
需要两个jar文件< img src =https://i.stack.imgur.com/25KnA.pngalt =sample>
- barcode4j：2.1
- qrgen：1.4
<我已经在lib文件夹中添加了这些jar文件&尝试运行它。这样，当我在lib文件夹中添加qrgen时，我得到404错误。
我尝试使用maven，我添加了依赖，如下所示：
< dependency>
< groupId> net.glxn< / groupId>
< artifactId> qrgen< / artifactId>
< version> 1.4< / version>
< / dependency>
< dependency>
< groupId> net.sf.barcode4j< / groupId>
< artifactId> barcode4j-light< / artifactId>
< version> 2.1< / version>
< / dependency>
但我得到第二个依赖的错误，所以我复制了lib文件夹中的barcode4j，但我无法打印QR码。请帮助我。

解决方案
我猜你一切都好。但是你错过了一件事。你使用的qrgen-1.4进一步依赖 zxing-core-2.0 & zxing-javase 尝试将这两个jar文件包含到您的构建路径中，这些可能会很好用。
I am using primefaces to develop a web app.I am trying to show the bar code on mhe webpage.All coders are shown except the QR code.I have read that two jar files are required for this
- barcode4j: 2.1
- qrgen: 1.4
I have added these jar files in the lib folder & try running it.In this way i get 404 error when i add qrgen in lib folder.
I tried doing it using maven i added the depedency as follows:
<dependency>
<groupId>net.glxn</groupId>
<artifactId>qrgen</artifactId>
<version>1.4</version>
</dependency>
<dependency>
<groupId>net.sf.barcode4j</groupId>
<artifactId>barcode4j-light</artifactId>
<version>2.1</version>
</dependency>
but i get error for second dependency so i copied the barcode4j in lib folder but i can't print the QR code.please help me out.

解决方案
I guess you're doing all ok.But you missed on one thing.The qrgen-1.4 you are using are further having dependencies as zxing-core-2.0 & zxing-javase trying including these two jar files into your build path these might work well.
