我有两个项目可以自己正确运行但是当我在TradingFramework中包含MailSender时,我得到了这个NoClassDefFoundError:

我已经排除了相互冲突的罐子,但它仍然是相同的.这是pom.xml文件:

我正在尝试使用正则表达式检查密码是否为字母数字，但没有得到我期望的结果。下面的代码有什么问题？

boolean passwordOnlyAlphaNumericCheck = false;
Pattern patternAlphaNumericCheck = Pattern.compile("^[a-zA-Z0-9]$");
Matcher matcherAlphaNumericCheck = patternAlphaNumericCheck.matcher(login.getPassword());
if(matcherAlphaNumericCheck.find())
  passwordOnlyAlphaNumericCheck = true;

感谢帮助
