我想在服务器中使用 TrueZIP 7.7 库来解压缩用户上传的档案。我不打算使用加密档案，尤其是因为这是一个服务器，所以我不需要 Swing 弹出窗口来请求密钥。然而，当我为解压缩文件创建了一些简单的测试时，它因以下错误而失败：

是否可以完全禁用 TrueZIP 密钥管理，或者至少确保它不需要任何 Swing 组件来提取 ZIP 文件？

使用 TrueZIP，您必须满足 TrueZIP Driver ZIP 对 TrueZIP Swing 的依赖性，否则您将无法摆脱此异常。只要您的应用程序没有遇到 WinZip AES 加密条目，密钥管理器弹出窗口就不会出现。你也可以按照这篇文章实现你自己的密钥管理：http: //truezip.java.net/truezip-driver/truezip-driver-zip/key-management.html（但你仍然需要满足这个依赖）。

或者，您可以迁移到TrueVFS。TrueVFS 具有更加模块化的体系结构，您只需在类路径中添加TrueCommons KeyManager Disable模块即可获得相同的效果。
