java - Spring Cloud java.lang.IllegalStateException : Cannot load environment

Question

我正在尝试运行 Spring Cloud Config 应用程序，但出现错误。

构建.gradle

buildscript {
    ext {
        springBootVersion = '2.0.0.RELEASE'
    }
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'

group = 'com.demo'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = 1.8

repositories {
    mavenCentral()
    maven { url "https://repo.spring.io/snapshot" }
    maven { url "https://repo.spring.io/milestone" }
}


ext {
    springCloudVersion = 'Finchley.BUILD-SNAPSHOT'
}

dependencies {
    compile('org.springframework.boot:spring-boot-starter-web')
    compile('org.springframework.cloud:spring-cloud-config-server')
    testCompile('org.springframework.boot:spring-boot-starter-test')
}

dependencyManagement {
    imports {
        mavenBom "org.springframework.cloud:spring-cloud-dependencies:${springCloudVersion}"
    }
}

下面是资源文件夹中存在的 application.yml 文件。应用程序.yml

server:
  port: 8085

spring:
  cloud:
    config:
      server:
        git:
          uri: https://github.com/[DEMO]/TProj

https://github.com/[DEMO]/TProj 包含 application.yml 文件

我收到以下错误请求处理失败；嵌套异常是 java.lang.IllegalStateException:无法加载环境

错误:

问题的原因可能是什么？我怎么解决这个问题？这是网络或代理问题吗？

Answer 1

我通过在 application.properties 文件中添加“spring.cloud.config.server.git.uri”属性解决了此问题。虽然我使用的是 Maven 而不是 Gradle。

我们需要将以下内容添加到配置服务器的 application.properties 文件中:

spring.cloud.config.server.git.uri=file:///C:/folder-to-your-local-gitconfig-repo-where-the-property-file-has-been-saved

此外，请确保文件的路径不包含任何空格。

希望这可能有所帮助。
