Java Barcode Generation Technology-barcode4j

backgroundat present, the application of two-dimensional code has been spread all over the Internet platform, usually the unique number of products/commodities stored in the QR code to do scanning code recognition. and the bar code technology for production environment still exists, such as hardware equipment manufacture, supply, logistics transportation and so on. in the common product information management, material order system, there are multiple requirements scenarios for generating and printing barcodes (one-dimensional code).  Solution SolutionsJava Barcode Generation Scheme--barcode4j, zxingbarcode4jbarcode4j Open source Java Barcode Generation Library. Supports multiple encoding formats, such as: code-39,code-128, etc.http://barcode4j.sourceforge.net/ zxingis a 1d/2d codec class library made by Google Open source. The goal is to decode the QR code, Data Matrix, and UPC 1D barcodes. It offers a variety of platforms under which clients include: J2ME, J2se and Android this time using barcode4j as a solution Environment Preparation Download Barcode4j-lightBARCODE4J relies on a slightly bloated Lib package, which includes the Avalon-framework/servelet-api,so this selection is a lightweight version of the barcode4j-light   maven Addresshttp://mvnrepository.com/artifact/net.sf.barcode4j/barcode4j-light/2.0
