SpringBoot实现随机生成10位数字和字母组合

• 背景：需要随机生成10位数字和字母组合，提供为第三方的临时密码

• import java.util.Random;
  public class RandomGenerator {
      private static final String CHAR_LIST = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789";
      public static String generateRandomString(int length) {
          StringBuilder sb = new StringBuilder(length);
          Random random = new Random();
          for (int i = 0; i < length; i++) {
              int index = random.nextInt(CHAR_LIST.length());
              sb.append(CHAR_LIST.charAt(index));
          }
          return sb.toString();
      }
      public static void main(String[] args) {
          System.out.println(generateRandomString(10));
      }
  }
