java.lang.IllegalStateException：无法从位置“classpath:/application.yml”加载属性源

Question

我遇到了 Spring Cloud 项目的以下错误。在这个项目中，除了从 GIT 读取 .properties 文件外，我没有做任何特别的事情。

请指导这里还有什么需要更正的？

我们如何解决以下错误？ 应用.yml

 ---
server:
  port: 8888

spring:
  cloud:
    config:
      server:
        git:
          uri: https://github.com/rseroter/pluralsight-spring-cloudconfig-wa-tolls

          search-paths:
          - 'station*'
          repos:
            perf:
              pattern:
                - "*/perf"
                uri: https://github.com/rseroter/pluralsight-spring-cloudconfig-wa-tolls-perf

Answer 1

尝试删除引号

---
server:
  port: 8888

spring:
  cloud:
    config:
      server:
        git:
          uri: https://github.com/rseroter/pluralsight-spring-cloudconfig-wa-tolls

          search-paths:
          - 'station*'
          repos:
            perf:
              pattern:
                - */perf ##as it was trying to match the whole pattern
                uri: https://github.com/rseroter/pluralsight-spring-cloudconfig-wa-tolls-perf

                search-paths:
                - 'station*'

如果仍然无效，请尝试以下操作

repos:
  perf:
    pattern: xx*/perf, */pref ##as the fist character can't be a wild card but it can accept multiple value.
    uri: https://github.com/rseroter/pluralsight-spring-cloudconfig-wa-tolls-perf

在处理 yml 文件时寻找正确的缩进也很重要。

此错误表明 application.yml 的格式存在问题。您可以在线验证您的 yml 文件： http ://www.yamllint.com/
