您的代碼不提供查詢的供應商值。也許你可以在這種情況下使用準備好的聲明？ –

感謝它解決了這個錯誤，但是數據沒有插入在cqlsh中創建的表中。 –

你能夠從cqlsh插入數據嗎？ –

聲明ST = con.createStatement（）;

您應該使用PreparedStatement而不是Statement。例如：

PreparedStatement ps = conn.prepareStatement("insert into members(fname,lname,email,uname,pass) values (?,?,?,?,?)"); 
ps.setString(1,fname); 
ps.setString(2,lname); 
    ...
