Question

我想在服务器中使用TrueZIP 7.7库来解压缩用户上传的档案。我不打算使用加密存档，特别是，因为这是一个服务器，我不需要Swing弹出窗口来请求密钥。然而，当我创建一个解压缩文件的简单测试时，它失败并出现此错误：

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？

Answer 1

使用TrueZIP，您必须满足TrueZIP驱动程序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，就不会出现密钥管理器弹出窗口。您还可以通过以下文章实现自己的密钥管理：http://truezip.java.net/truezip-driver/truezip-driver-zip/key-management.html（但您仍需要满足此依赖关系）。

或者，您可以迁移到TrueVFS。 TrueVFS具有更加模块化的架构，您只需在类路径上添加TrueCommons KeyManager Disable模块即可获得相同的效果。
