MySQL blob 保存 word 乱码
java.io.File file = new java.io.File(file_name);  
java.io.FileInputStream fis = new java.io.FileInputStream(file);

String str_tz="insert into XX values(?,?);"; 
PreparedStatement stmt_tz=conn.prepareStatement(str_tz); 
stmt.setString(1,id);
stmt.setBinaryStream(2,fis,(int)file_up.length());
stmt.executeUpdate();
stmt.close();

保存图片没有问题,保存空白doc也没有问题
保存有中文内容的doc就出现乱码

应该是FileInputStream读取中文的问题?
不知道该怎么解决了!

改成byte试试
Java code
public static String getCode(byte[] bs) {

        ImageIcon icon = new ImageIcon(bs, "hello");
        Object ob = JOptionPane.showInputDialog((Component) null, "", "输入验证码",
                JOptionPane.INFORMATION_MESSAGE, icon, null, "");

        return (String) ob;
    }
    public static void File() throws Exception {
        File file = new File("F:\\psp\\picture\\she\\hebe.jpg");
        FileInputStream out = new FileInputStream(file);

        byte[] bs = new byte[out.available()];

        out.read(bs);
        System.out.println(getCode(bs));
    }

保存的word编码与进入保存数据库的编码要做转换。
