排查思路:
- 检查yml文件格式内容是否有误(请注意:是远程yml配置文件)
- 确认服务端的路径正确(服务端3344)
server:
port: 3344
spring:
application:
name: cloud-config-center # 服务名称
cloud:
config:
server:
git:
# uri: [email protected]:NoMessages/sprincloud-config.git # 填写你自己的github路径
uri: https://github.com/NoMessages/sprincloud-config.git # 填写你自己的github路径
# 搜索目录
search-paths:
- springcloud-config
# 阅读分支
label: master
# 注册到eureka
eureka:
client:
service-url:
defaultZone: http://localhost:7001/eureka
- 确保服务端的yml配置文件无误(bootstrap.yml)
server:
port: 3355
spring:
application:
name: config-client
cloud:
config:
label: master # master分支
name: config # 读取config配置文件 前缀
profile: dev # 后缀为dev
uri: http://localhost:3344 # 相当于是从服务端获取数据而不是github
eureka:
client:
service-url:
defaultZone: http://eureka7001.com:7001/eureka
- 检查配置是否对应远程yml配置文件内容(3355客户端)
@RestController
public class ConfigClientController {
@Value("${info}") <----- 这个对应的是远程仓库的info 请注意
private String configInfo;
@GetMapping("/configInfo")
public String getConfigInfo(){
return configInfo;
}
}
最终访问效果:
