NoSuchLabelException：没有这样的标签Spring云服务器

Question

我正在创建基本的spring云服务器，我有一个项目配置服务器:

application.properties

spring.application.name=zuulMicroservice
server.port=8888

spring.cloud.config.server.git.uri=file:///C:/Users/rober/git/microservices/config
#spring.cloud.config.server.git.uri=https://github.com/robertofdez97/microservices.git/config
#spring.profiles.active=native

主类

@EnableConfigServer
@SpringBootApplication
public class ConfigServerApplication {

    public static void main(String[] args) {
        SpringApplication.run(ConfigServerApplication.class, args);
    }

}

和另一个项目名称项：

application.properties

spring.application.name=itemsMicroservice
server.port=8002

eureka.client.service-url.defaultZone=http://localhost:8761/eureka

在路径文件：///C：/User/rober/git/microservices/config中，我有文件itemsMicroservice.properties包含：

server.port = 8005

在postman中，我有以下请求localhost:8888/itemsMicroservice/default，并获得以下消息

在git中，我有2个分支主节点和开发，但我的所有代码都在开发分支中。C：用户/rober/git/微服务是我的本地存储库，我创建了文件夹“config”，并创建了属性文件。后来当我播种它不起作用时，我使用文件夹中的命令“git init”

谢谢你的帮助，对不起，我的英语不是我的母语

Answer 1

如果您使用的是最新的git版本，它会将第一个分支名称创建为“main”，而不是以前版本中的“master”。检查此链接以更改分支名称

本质上，应该添加一个新属性来更改默认标签:

spring.cloud.config.server.git.default-label=main
