Question

我有git的spring cloud配置服务器和客户端应用程序，其设置如下：春季靴子：2.1.17-快照 java：1.8

服务器运行正常。

但是客户端无法获取服务器详细信息。

它引发以下错误：无法解析值“ $ {rate}”中的占位符“ rate” 费率是属性的一部分。

服务器pom.xml：

  public MainPage()
    {
        InitializeComponent();

        webview.Navigating += Webview_Navigating;

    }

    private void Webview_Navigating(object sender, WebNavigatingEventArgs e)
    {
        var url = e.Url;

        if (url.Contains("example.com"))
        {
           //...
        }

    }

服务器bootstrap.yaml：

这可以正确构建服务器，并且调用http：// localhost：8888 / s1rates / default可以正常工作。

但是客户端没有这样做。

客户端pom.xml：

---
server:
  port: 8888
spring:
  cloud:
    config:
      server:
        git:
          uri: https://github.com/hardik92/spring-cloudconfig-tolls
#          username: uname
#          password: pwd
          search-paths:
           - 'station*'
          repos:
            perf:
              pattern:
                - "*/perf"
              uri: https://github.com/hardik92/spring-cloudconfig-tolls-perf
              search-paths:
                - 'station*'

客户端bootstrap.properties：

我看到了许多类似的问题，但是没有一个答案对我有帮助。由于没有足够的代表，我无法在此处发表评论或添加答案。

我在SpringBoot 2.4中尝试了相同的操作，但是发生了相同的错误。

任何帮助将不胜感激。

谢谢，哈迪克

Answer 1

此问题与Spring Boot不相关，但与Spring Cloud有关。有关Spring Cloud 2020.0.0-M5中重大更改的详细列表，请参见Spring Cloud 2020.0 Release Notes。

请特别注意指定默认情况下未启用引导程序的部分。启用它的一种方法是将以下Maven依赖项添加到项目POM文件中：

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-bootstrap</artifactId>
</dependency>

这样，无论何时启动Spring Cloud配置服务器客户端，都应该看到它正确地从Spring Cloud配置服务器中获取了相关的属性值。实际上，您的控制台日志应指定以下事实：

2020-11-30 19:17:26.800  INFO 9891 --- [           main] c.c.c.ConfigServicePropertySourceLocator : Fetching config from server at : http://localhost:8888

无论如何，希望您到目前为止已经解决了这个问题；-）

Answer 2

不穿衣服

spring.cloud.config.uri = http：// localhost：8888

到

spring.cloud.config.uri = http：//127.0.0.1：8888

它适用于弹簧靴2.1.17.BUILD-SNAPSHOT。

但是sprint引导2.4.0-SNAPSHOT仍然失败。

当服务器连接到git时，Spring Cloud Config客户端无法连接到服务器
