1.去http://barcode4j.sourceforge.net/下载文件,(源代码和生成好的都要下载)
2.解压barcode4j-2.0alpha2-bin.zip这个包，在build目录下有barcode4j.jar，在lib目录下有avalon-framework-4.2.0.jar， 将barcode4j.jar和avalon-framework-4.2.0.jar添加到项目的lib中,eclipse中只要复制到web-inf下面的lib里面就OK了. 54ne.com
3.解压将barcode4j-2.0alpha2-src.zip，将srcjavaorgkrysalisbarcode4jservlet目录下的BarcodeServlet.java类的代码拷出来，修改默认的图片显示方式，找到 if (format == null) format = MimeTypes.MIME_JPEG;这一行,表示默认的格式为JPEG文件 网管网bitsCN_com
4.将以下这段servlet配置在web.xml中
| <servlet> <servlet-name>BarcodeServlet</servlet-name> <servlet-class>com.yourname.BarcodeServlet</servlet-class> </servlet> <servlet-mapping> |

5.在页面中添加<img src="<%=request.getContextPath() %>/barcode?msg=12345678" height="50px" width=130px/> 网管网bitsCN_com
type是生成条形码的类型:
看例子就明白了
| <table border="1"> <tr> <td> <h1>code39</h1> <img src="<%=request.getContextPath()%>/barcode?msg=0123456789&type=code39" height="100px" width=300px/> </td> <td> <h1>code128</h1> <img src="<%=request.getContextPath()%>/barcode?msg=0123456789&type=code128" height="100px" width=300px/> </td> <td> <h1>Codabar</h1> <img src="<%=request.getContextPath()%>/barcode?msg=0123456789&type=codabar" height="100px" width=300px/> 网管网bitsCN.com </td> </tr> <tr> <td> <h1>intl2of5</h1> <img src="<%=request.getContextPath()%>/barcode?msg=01234567890540&type=intl2of5" height="100px" width=300px/> </td> <td> <h1>upc-a</h1> <img src="<%=request.getContextPath()%>/barcode?msg=012345678912&type=upc-a" height="100px" width=300px/> </td> <td> <h1>ean-13</h1> <img src="<%=request.getContextPath()%>/barcode?msg=200123457893&type=ean-13" height="100px" width=300px/> </td> <td> <h1>ean-8</h1> 中国网管论坛bbs.bitsCN.com <img src="<%=request.getContextPath()%>/barcode?msg=20123451&type=ean-8" height="100px" width=300px/> </td> </tr> <tr> 54com.cn </td> <td> <h1>datamatrix</h1> <img src="<%=request.getContextPath()%>/barcode?msg=20123451&type=datamatrix" height="100px" width=300px/> </td> </tr> </table> 中国网管联盟www_bitscn_com |
