String sql = "select * from images";
ResultSet rs = query.executeQuery(sql);
rs.next();
InputStream in = rs.getBinaryStream("image");
ServletOutputStream sos = response.getOutputStream();
int len = 0;
byte[] b = new byte[1024];
response.reset();
response.setContentType("image/gif");
while((len = in.read(b)) > 0)
sos.write(b,0,len);
in.close();
sos.close();

如果是写到文件只要把sos
定义为DataOutputStream sos = new DataOutputStream(new BufferedOutputStream(new FileOutputStream("/a.gif")));
