java 应用程序执行时不使用 application.yml 中 spring.cloud.config 的设置

Settings in application.yml for spring.cloud.config aren't used when app is executing

提问by slippery

I have a problem with spring cloud: my settings in application.yml for spring.cloud.config aren't used when app is executing. let me put more detail here. I'd like to my services could get settings from a remote ConfigServer. I've created the ConfigServer as a spring boot app with annotation @EnableConfigServer. After that i've created client app with next config file:

我对 spring cloud 有问题：我在 application.yml 中为 spring.cloud.config 设置的设置在应用程序执行时没有使用。让我在这里提供更多细节。我希望我的服务可以从远程 ConfigServer 获取设置。我已将 ConfigServer 创建为带有注释 @EnableConfigServer 的 Spring Boot 应用程序。之后，我使用下一个配置文件创建了客户端应用程序：

    application:
      name: mw
    cloud:
      config:
        enabled: true
        uri: http://172.17.42.1:8888
        fail-fast: true

main class:

主类：

    @EnableEurekaClient
    @SpringBootApplication
    public class MwApplication

and extra configuration into app:

并在应用程序中进行额外配置：

    @Configuration
    @EnableJpaRepositories(basePackages = {"com.sample.repository"})
    @EnableTransactionManagement
    @EnableScheduling
    public class AppConfiguration

also i have next dependencies:

我还有下一个依赖项：

    spring-cloud-starter-eureka
    spring-cloud-config-client
    spring-boot-configuration-processor
    spring-boot-starter-data-jpa

When i execute my client app, i've got this message: ConfigServicePropertySourceLocator : Could not locate PropertySource: I/O error on GET request for "http://localhost:8888/mw/default"

当我执行我的客户端应用程序时，我收到以下消息：ConfigServicePropertySourceLocator : 无法定位 PropertySource: I/O error on GET request for " http://localhost:8888/mw/default"

The app try to get data from default uri(localhost) instead of to use uri from my setting. I've looked at app in debug mode and saw org.springframework.cloud.config.client.ConfigServiceBootstrapConfiguration was creating ConfigClientProperties with default property and my settings from application.yml weren't used.

该应用程序尝试从默认 uri(localhost) 获取数据，而不是从我的设置中使用 uri。我在调试模式下查看了应用程序，看到 org.springframework.cloud.config.client.ConfigServiceBootstrapConfiguration 正在创建具有默认属性的 ConfigClientProperties 并且我没有使用 application.yml 中的设置。

What am i doing wrong? thanks.

我究竟做错了什么？谢谢。

You need to add the following to your application.yml file:

您需要将以下内容添加到 application.yml 文件中：

spring:
    cloud:
        config:
            enabled: true

Per comment chain, you also need to add the properties to bootstrap.yml instead of application.yml . The reason is that the former is loaded before the latter in the spring startup cycle. Here is another SO post answered by user Michael Isvy explaining why, and copied below for posterity: What is the diference between putting a property on application.yml or bootstrap.yml in spring boot?

每个注释链，您还需要将属性添加到 bootstrap.yml 而不是 application.yml 。原因是前者在spring启动循环中先于后者加载。这是用户 Michael Isvy 回答的另一篇 SO 帖子，解释了原因，并在下面复制以供后代使用：spring boot 中将属性放在 application.yml 或 bootstrap.yml 上有什么区别？

I have just asked the Spring Cloudguys and thought I should share the info I have here.

bootstrap.yml is loaded before application.yml.

It is typically used for the following:

• when using Spring Cloud Config Server, you should specify spring.application.nameand spring.cloud.config.server.git.uriinside bootstrap.yml
• some encryption/decryptioninformation

Technically, bootstrap.ymlis loaded by a parent Spring ApplicationContext. That parent ApplicationContext is loaded before the one that uses application.yml.

我刚刚问了Spring Cloud这些人，并认为我应该分享我在这里的信息。

bootstrap.yml 在 application.yml 之前加载。

它通常用于以下情况：

• 当使用 Spring Cloud Config Server 时，你应该指定spring.application.nameand spring.cloud.config.server.git.uriinsidebootstrap.yml
• 一些encryption/decryption信息

从技术上讲，bootstrap.yml由父 Spring ApplicationContext 加载。该父 ApplicationContext 在使用 application.yml 的那个之前加载。
