推荐答案

使用getString的方式是错误的. 您可以传递索引或列标签:

The way you use getString is wrong. You can pass an index or the column label:

System.out.println("DESC : "+rs.getString(1));

或

System.out.println("DESC : "+rs.getString("description"));

您将索引作为String传递，这是错误的.

you pass the index as a String and that's wrong.
