jdbc连接mysql后数据插不进去，什么问题？

public class test {
    public static void main(String[] args) {         
            try {
                 String info = "abcd";
                  
                    System.out.println(info);
                     
                    String sql = "insert into goods (goods) values ( ? )";
                    PreparedStatement ps = ConnectDB.getConnection().prepareStatement(sql);
                    ps.setString(1,info );
                     
                    ps.executeUpdate();
                 
                    ps.close();
                 
            } catch (MalformedURLException e) {
                e.printStackTrace();
            } catch (ParserException e) {
                e.printStackTrace();
            } catch (IOException e) {       
                e.printStackTrace();
            } catch (SQLException e) {
                e.printStackTrace();
            } catch (Exception e) {
                e.printStackTrace();
            }

大神看下这样写 有什么问题
