我会使用 spring-cloud-bus 来刷新配置应用程序。目前我的工作失败了。似乎配置与旧版本不完全相同。 在我的配置服务器 pom：

<?xml version="1.0" encoding="UTF-8"?>

在服务器配置 application.yml

spring:
  application:
    name: configuration-server
  cloud:
    config:
      server:
        git:
          uri: git@github.com:myrepository/myApplicationsConfig.git
          clone-on-start: true
          default-label: master
        health: false
      enabled: true

    bus:
      enabled: true
  profiles:
    active: development
  rabbitmq:
    host: rabbitIP
    port: rabbitPort
    username: username
    password: password
    virtual-host: /

eureka:
  instance:
    leaseRenewalIntervalInSeconds: 10
    client:
      registryFetchIntervalSeconds: 5

在应用程序中进行配置

pom：（ 父级的spring boot和spring cloud依赖版本相同）

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <parent>
    <groupId>my.app.to.configure</groupId>
    <artifactId>app-to-configure</artifactId>
    <version>1.2.0-SNAPSHOT</version>
  </parent>
  <groupId>my.app.to.configure</groupId>
  <artifactId>web-application</artifactId>
  <name>web-application</name>

  <properties>
    <java.version>1.8</java.version>
  </properties>

  <dependencies>
    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
      <groupId>org.springframework.cloud</groupId>
      <artifactId>spring-cloud-starter-config</artifactId>
    </dependency>
    <dependency>
      <groupId>org.springframework.cloud</groupId>
      <artifactId>spring-cloud-starter-bootstrap</artifactId>
    </dependency>
    <dependency>

      <artifactId>lombok</artifactId>
      <optional>true</optional>
      <scope>provided</scope>
    </dependency>
...
  </dependencies>
...

在 application.yml 中：

spring:
  application:
    name: my-application-to-configure
  cloud:
    config:
      discovery:
        enabled: true
        service-id: configuration-server
      profile: development

eureka:
  instance:
    leaseRenewalIntervalInSeconds: 10
    client:
      registryFetchIntervalSeconds: 5

目前，当我在 github 上更新配置时，webhook 调用 configuration-server 但我有 400 错误。在配置服务器日志中，我有：

Resolved [org.springframework.web.bind.MissingServletRequestParameterException: Required List parameter 'path' is not present]

我不明白什么是“路径”。你能给我一些帮助吗？谢谢。
