在我目前的项目中，我一直在使用 apache nifi 进行一些实验。
当我第一次配置时。 nifi 运行完美(当我输入 http://localhost:8080/nifi/ 时，我能够在 Google Chrome 上看到 Canvas 和工具栏)。但是，在重新启动计算机一次后，我无法运行它。
当我键入 nifi.0.7.0\bin\run-nifi.bat 命令时，我在控制台上看到以下消息。

你能告诉我问题是什么吗？我该如何解决这个问题？

并且 nifi-user.log 是空。
当我尝试调用 localhost:8080/nifi/ 时，我看到以下内容。
最佳答案
尝试检查配置文件是否有以下键“nifi.sensitive.props.key=”和一个值。 如果为空，请设置一个 key ，如示例“nifi.sensitive.props.key=132134”。
如果您仍然遇到麻烦，请观看此视频，应该有所帮助。 https://www.youtube.com/watch?v=DDd6KayUHt8
祝一切顺利
