java - 在 MySQL 中保存 3gp 文件时出现 ArrayIndexOutOfBoundsException

Question

我的代码是:

psmnt = conn.prepareStatement("INSERT INTO upload_data(user_id,photo,audio) " + "values(?,?)");
psmnt.setLong(1, userId);   
fis = new FileInputStream(photoFile);
psmnt.setBinaryStream(2, (InputStream) fis, (int) (photoFile.length()));
fisAudio =  new FileInputStream(audioFile);
psmnt.setBinaryStream(3, (InputStream) fisAudio, (int) (audioFile.length()));
int s = psmnt.executeUpdate();

MySQL数据库中的音频类型为blob。

异常(exception)是:

psmnt.setBinaryStream(3,

Jennifer，你正在尝试设置第三个参数，但你的插入中只有两个:

psmnt = conn.prepareStatement("INSERT INTO upload_data(user_id,photo,audio) "
                        + "values(?,?)");
