先去該網頁下載套件
建立一個barcode.jsp
<%@ page import="com.businessrefinery.barcode.*"%>
<%
String barcodes = request.getParameter("barcode");//收到barcode然後套入到套件內
try {
Barcode barcode = new Barcode();
barcode.setSymbology(Barcode.CODE128);
barcode.setCode(barcodes);
response.setContentType("image/jpeg");
// response.setHeader("Pragma", "no-cache");
// response.setHeader("Cache-Control", "no-cache");
// response.setDateHeader("Expires", 0);
ServletOutputStream servletoutputstream = response.getOutputStream();
barcode.drawOnStream(servletoutputstream);
} catch (Exception e) {
throw new ServletException(e);
}
%>
<%
String barcodes = request.getParameter("barcode");//收到barcode然後套入到套件內
try {
Barcode barcode = new Barcode();
barcode.setSymbology(Barcode.CODE128);
barcode.setCode(barcodes);
response.setContentType("image/jpeg");
// response.setHeader("Pragma", "no-cache");
// response.setHeader("Cache-Control", "no-cache");
// response.setDateHeader("Expires", 0);
ServletOutputStream servletoutputstream = response.getOutputStream();
barcode.drawOnStream(servletoutputstream);
} catch (Exception e) {
throw new ServletException(e);
}
%>
然後，再透過
<img src="barcode.jsp?barcode=TW000002721" border=0 width="80" height="20"/>
的方式去呼叫他
(這個大小我測試過了 機器剛好讀的到!)
