java - 运行由 jetty, jackson 实现的服务器时遇到的错误
问题描述
我正在尝试运行由其他人实现的服务器。
这是我正在尝试运行的项目的链接。
https://github.com/mccorby/PhotoLabellerServer
我按照存储库的 README.md 文件中给出的说明进行操作。
- 我手动创建了 currentRound.json 文件
- 我修改了
local.propertiesserver模块下的文件（指定了保存训练好的模型的目录） - 我成功运行了
Main.kt正在训练初始模型的文件。训练好的模型成功保存在我在local.properties文件中指定的目录中。 - 然后，我尝试运行
JobQueueServer.java. 服务器已成功启动，但是 RestService 根本不工作。我试图通过点击来检查服务器是否已启动http://localhost:9997/service/federatedservice/available。然后它返回以下错误。
简单的错误信息：
这是视频的链接，显示了我如何面对错误。
https://youtu.be/cQFvegW-JXo
我将在本文末尾发布完整的错误消息。
根据错误报告，它表明代码jacksonObjectMapper().readValue(getCurrentRoundJsonFile())导致了错误。
错误：
12:24:48 AM: Executing task 'JobQueueServer.main()'...
