我不确定这是一个错误还是我做错了。无论哪种情况，我都需要别人的帮助。
我们在 Web 应用程序中将 Jasypt 和 Spring 2.05 结合在一起，我们在其中加密了属性文件中的一些密码。这件事在 Web 应用程序上运行良好。我们甚至可以使用 BasicTextEncrypor.decrypt(method) 从主方法中解密密码。
但是，我们在执行 JUnit 测试用例时遇到了问题。一旦我们运行测试套件，我们就会得到以下堆栈跟踪。

我深入研究了 Jasypt 的源代码，才知道在幕后抛出了 javax.crypto.BadPaddingException。我不确定为什么直接从 main 方法进行相同的调用和通过 JUnit 框架执行相同的事情之间存在差异，其他一切（例如密码）都是相同的。
