今天练习分布式配置中心,写config-client配置文件,使用bootstrap.properties配置,运行没有问题。
bootstrap.properties:
spring.application.name=config-client spring.cloud.config.label=master spring.cloud.config.profile=dev spring.cloud.config.uri= http://localhost:8888/ server.port=8881 #spring.cloud.config.label 指明远程仓库的分支 #spring.cloud.config.profile #dev开发环境配置文件 #test测试环境 #pro正式环境 #spring.cloud.config.uri= http://localhost:8888/ 指明配置服务中心的网址。 #spring.cloud.config.discovery.enabled 是从配置中心读取文件。 #spring.cloud.config.discovery.serviceId 配置中心的servieId,即服务名
但是我使用了bootstrap.yml配置文件,启动报错:
bootstrap.yml:
spring: application: name: config-client server: port: 8881 spring: cloud: config: label: master profile: dev uri: http://localhost:8888/
报错如下:

报错信息显示无法加载配置文件,原因是重复建“spring”。
解决:yml文件在单一文件中,可用连续三个连字号(---)区分多个文件。更改bootstrap.yml:
spring: application: name: config-client server: port: 8881 --- spring: cloud: config: label: master profile: dev uri: http://localhost:8888/
重启,运行成功。
