java.lang.IllegalStateException：无法从位置加载属性源＆＃39; classpath：/application.yml'

Question

我在 Spring Cloud 项目中遇到以下错误。在这个项目中，除了从GIT读取.properties文件之外，我没有做任何特别的事情。

请指导此处需要纠正的其他内容？

我们如何解决以下错误？ 的 application.yml

server:
  port: 8888

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

          search-paths:
          - 'station*'
          repos:

              pattern: 
                - "*/perf"
                uri: https://github.com/rseroter/pluralsight-spring-cloudconfig-wa-tolls-perf

                search-paths:
                - 'station*'

Answer 1

此错误表示应用程序的格式存在问题。 您可以在线验证yml文件： http://www.yamllint.com/

Answer 2

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

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

在使用yml文件时，查找正确的缩进也很重要。

Answer 3

我今天遇到了这个错误，起初我并不理解，因为我的conf缩进效果很好。然后我意识到那是因为我的application.yml的编码是“ Microsoft something ”（由IntelliJ建议，不记得确切了）。我只复制了conf，粘贴到SublimeText中，删除了application.yml，然后重新创建了一个同名的新文件（所以 private void ponaredek_MouseDown(object sender, MouseButtonEventArgs e) { mouseDown = true; //x1 = System.Windows.Forms.Control.MousePosition; x1 = new System.Drawing.Point((int)e.GetPosition(this).X, (int)e.GetPosition(this).Y); } ），复制了SublimeText中的内容，然后粘贴到了我的新文件中。 显然，默认编码解决了该问题。

Answer 4

我有相同的问题，已经解决。如果application.yml文件做得很好，您可以尝试清空Maven存储库（位于Maven /存储库）。然后在项目中进行maven更新，然后再次运行。

Answer 5

我不确定第二个search-paths，我想您误把它放在了那里。但是对于第17和18行中的错误消息，这很容易解决：

在包含uri的行中添加另一个破折号，使其看起来像这样：

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

pattern:之后的内容应该是列表，您需要在项目前加上-。

Answer 6

我正面临类似的问题...原因之一是yaml文件中的间距不正确。我已解决如下-

示例-

incorrect one ->
    RESERVATION:
      registerHealthIndicator: true
        slidingWindowSize: 100   --> this parameter have unnecessary spaces at beginning

the correct one is ->

    RESERVATION:
      registerHealthIndicator: true
      slidingWindowSize: 100      --> correct as spaces at beginning removed

请参考下图-

Answer 7

如果其他答案没有帮助，并且您像我一样使用 IntelliJ，请尝试重新加载 Gradle 项目，该项目已为我修复。
