Java 无法从'；可选：配置服务器：http://localhost:8090 -SpringBoot 2.4.0伊尔福德2020.0.0-M3

有关新SpringBoot 2.4.0的问题，请回答

首先，我们将配置服务器和配置客户端升级为SpringBoot 2.4.0+Illford 2020.0.0-M3

然后，我们遵循设置属性的“新方法”，并希望继续使用这种新方法

因此，我在application.properties中对此进行了配置（请参见spring.config.import）

然后，我们删除了旧的但仍在工作的bootstrap.properties

server.port=8010
spring.application.name=mycoolservice
spring.cloud.config.uri=${SPRING_CLOUD_CONFIG_URI:https://localhost:8090}/config
spring.profiles.active=${SPRING_PROFILE_ACTIVE:local}

最后，我们启动了应用程序并观察到：

请问有什么问题

---

谢谢

这实际上是SpringBoot 2.4.0+Ilford 2020.0.0-M3组合的已知错误

为了解决这个特殊问题，SpringBoot 2.4.0需要Ilford 2020.0.0-M5

从M3升级到M5将解决此问题
