spring-boot - 已解决 [org.springframework.cloud.config.server.environment.NoSuchLabelException : No such label: master]

Question

阅读我的 gitHub 的问题:

spring.application.name=config-server

server.port=9101
spring.cloud.config.server.git.uri=https://github.com/cambyze/cambyze-properties.git
spring.cloud.config.server.git.username=cambyze-public
spring.cloud.config.server.git.password=CambyzePublic2020
spring.cloud.config.server.git.clone-on-start=true

GET http://localhost:9101/training-products/default 时，我收到以下消息

[nio-9101-exec-1] .m.m.a.ExceptionHandlerExceptionResolver : Resolved [org.springframework.cloud.config.server.environment.NoSuchLabelException: No such label: master]

postman 的这个完整结果

问题是默认创建的默认分支是 main 而不是 master。
为了修复它，我的新 application.properties 强制默认标签为“main”
spring.application.name=配置服务器

server.port=9101
spring.cloud.config.server.git.uri=https://github.com/cambyze/cambyze-properties.git
spring.cloud.config.server.git.username=cambyze-public
spring.cloud.config.server.git.password=CambyzePublic2020
spring.cloud.config.server.git.clone-on-start=true
spring.cloud.config.server.git.default-label=main
