macos - Quarkus：SRCFG00019：无法从 Converter 构造函数创建新实例

问题描述

我是这个框架的新手，我正在按照本指南使用 Quarkus https://quarkus.io/guides/redis设置数据库（redis）

但是，在设置 redis 并按照指南进行操作后，运行时出现以下错误

mvn quarkus:dev

解决方案

原来我在application.properties中设置的redis属性最后有个空格

quarkus.redis.hosts=redis://localhost:6379

我偶然发现了这个，因为我没有很多属性，我希望 quarkus 提供更好的堆栈跟踪。
