無法從bootstrap.yml讀取配置服務器uri

Question

我正在嘗試使用以下pom創建一個eureka服務器注冊表以連接到配置服務器，但它無法連接配置服務器，因為它無法從bootstrap.yml文件中讀取正確的配置服務器uri;

 <parent>
    <groupId>xxx</groupId>
    <artifactId>yyy</artifactId>
    <version>1.0.0-SNAPSHOT</version>
  </parent>
  <modelVersion>4.0.0</modelVersion>

  <artifactId>cloudregistryapp</artifactId>
  <version>1.0.0-SNAPSHOT</version>

  <dependencies>
    <dependency>
      <groupId>org.springframework.cloud</groupId>
      <artifactId>spring-cloud-starter-config</artifactId>
      <version>2.1.2.RELEASE</version>
    </dependency>
    <dependency>
      <groupId>org.springframework.cloud</groupId>
      <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
      <version>2.1.1.RELEASE</version>
      <exclusions>
        <exclusion>
          <groupId>javax.servlet</groupId>
          <artifactId>servlet-api</artifactId>
        </exclusion>
      </exclusions>
    </dependency>

我不得不排除servlet-api，但這是另一個主題。 在我的父pom（這是另一個maven模塊）;

 <parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.1.5.RELEASE</version>
    <relativePath/>
  </parent>

  <dependencyManagement>
    <dependencies>
      <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-dependencies</artifactId>
        <version>Greenwich.RELEASE</version>
        <type>pom</type>
        <scope>import</scope>
      </dependency>
    </dependencies>
  </dependencyManagement>

這是app / resources目錄中的bootstrap.yml ;

spring:
  application:
    name: cloudregistry
  cloud:
    config:
      fail-fast: true
      uri: http://localhost:8080

eureka:
  instance:
    prefer-ip-address: true
  client:
    registerWithEureka: false
    fetchRegistry: false
    server:
      waitTimeInMsWhenSyancEmpty: 0

我期待看到嘗試連接到localhost：8080 for config server。 但是它吐出了以下輸出;

並且它自然會引發連接異常，因為它無法識別bootstrap.yml文件中的URL。

任何幫助將不勝感激，謝謝。

Answer 1

失敗的主要原因是我使用自己的父pom，用spring-boot-starter-parent更改后它開始工作。

當然，我將所需的部分（例如distributionManagement復制到eureka服務的pom中。

主要原因是spring boot parent pom在pom中使用resources指令，如下所示;

<resources>
  <resource>
    <filtering>true</filtering>
    <directory>${basedir}/src/main/resources</directory>
  </resource>
</resources>

手動添加到項目就行了！
