使用Java实现在SQLserver中实现图片的存储

  Connection conn = null;
try{
DriverManager.registerDriver(new com.microsoft.jdbc.sqlserver.SQLServerDriver());
conn=DriverManager.getConnection("jdbc:microsoft:sqlserver://IP:1433;DataBaseName=Moftec","sa","mymm");
}
catch(Exception e )
{
//捕捉异常并抛出IOException
out.println("Can not connec to the database! The exception is " + e.toString());
}
FileInputStream fis=null;
File file = new File("E:/java/chart.jpg");
try{
fis = new FileInputStream(file);
}catch(FileNotFoundException e){
out.println("Not find file!");
}
PreparedStatement ps = conn.prepareStatement("Insert into gs_img (lei,years,img) values (?,?,?)");
ps.setString(1,"ivan");
ps.setInt(2,4);
ps.setBinaryStream(3,fis,(int)file.length());
ps.executeUpdate();
ps.close();
try{
fis.close();
out.println("写进去了！");
}catch(IOException e){
out.println("fis cann't cloase!");
}
 //注意 ps.setBinaryStream(3,fis,(int)file.length());这里有强制转换，如果文件太大超过范围就会出问题，其实象以前用ASP那样一般都是保存图片的路径，图片放到一个文件夹，这样读取大图会方便一点。
