这是报出的错误

@Test
public void testInsertBlob(){
Connection connection=null;
PreparedStatement preparedStatement=null;
try {
connection=JDBCTools.getConnection();
String sql = "INSERT INTO customers(name, email, birth,picture)" +
"VALUES(?,?,?,?)";
preparedStatement=connection.prepareStatement(sql);
preparedStatement.setString(1,"ABCDE");
preparedStatement.setString(2,"abce@qq.com");
preparedStatement.setDate(3,
new Date(new java.util.Date().getTime()));
InputStream inputstream=new FileInputStream("柳岩.jpg");
preparedStatement.setBlob(4, inputstream);
preparedStatement.executeUpdate(sql);
} catch (Exception e) {
e.printStackTrace();
}finally{
JDBCTools.releaseDB(null, preparedStatement, connection);
}
}
这是使用的jdbc程序

麻烦请教一下吧里的大神~
