Spring Cloud Config provides server and client-side support for externalized configuration

in a distributed system. With the Config Server you have a central place to manage

external properties for applications across all environments. The concepts on both client

and server map identically to the Spring Environment and PropertySource abstractions, so

they fit very well with Spring applications, but can be used with any application running

in any language. As an application moves through the deployment pipeline from dev to test

and into production you can manage the configuration between those environments and be

certain that applications have everything they need to run when they migrate. The default

implementation of the server storage backend uses git so it easily supports labelled

versions of configuration environments, as well as being accessible to a wide range of

tooling for managing the content. It is easy to add alternative implementations and plug

them in with Spring configuration.

快速入门(Quick Start)

Start the server:

The server is a Spring Boot application so you can run it from your IDE instead if you

prefer (the main class is ConfigServerApplication ). Then try out a client:

这个服务是一个Spring Boot应用,如果你喜欢你可以直接用IDE启动(main类

是 ConfigServerApplication ). 然后试着启动一个客户端:

The default strategy for locating property sources is to clone a git repository (at

spring.cloud.config.server.git.uri ) and use it to initialize a mini SpringApplication . The

mini-application’s Environment is used to enumerate property sources and publish them

via a JSON endpoint.

$ cd spring-cloud-config-server

$ ../mvnw spring-boot:run

$ curl localhost:8888/foo/development

{"name":"development","label":"master","propertySources":[

{"name":"https://github.com/scratches/config-repo/foo-development.properties","source":

{"bar":"spam"}},

{"name":"https://github.com/scratches/config-repo/foo.properties","source":{"foo":"bar"}}

默认加载property资源的策略是克隆一个git仓库(at spring.cloud.config.server.git.uri'),用它去

初始化一个mini `SpringApplication , 这个mini SpringApplication 的 Environment 用来枚举

property,通过json节点发布它们.

The HTTP service has resources in the form:

HTTP服务资源的构成:

where the "application" is injected as the spring.config.name in the SpringApplication

(i.e. what is normally "application" in a regular Spring Boot app), "profile" is an active

profile (or comma-separated list of properties), and "label" is an optional git label

(defaults to "master".)

application是 SpringApplication 的 spring.config.name ,(一般来说'application'是一个常规的

Spring Boot应用),profile是一个active的profile(或者逗号分隔的属性列表),label是一个可选的

git标签(默认为"master").

Spring Cloud Config Server pulls configuration for remote clients from a git repository

(which must be provided):

Spring Cloud Config Server从git仓库为为远程客户端拉取配置信息：

客户端示例(Client Side Usage)

To use these features in an application, just build it as a Spring Boot application that

depends on spring-cloud-config-client (e.g. see the test cases for the config-client, or

the sample app). The most convenient way to add the dependency is via a Spring Boot

starter org.springframework.cloud:spring-cloud-starter-config . There is also a parent pom

and BOM ( spring-cloud-starter-parent ) for Maven users and a Spring IO version management

properties file for Gradle and Spring CLI users. Example Maven configuration:

/{application}/{profile}[/{label}]

/{application}-{profile}.yml

/{label}/{application}-{profile}.yml

/{application}-{profile}.properties

/{label}/{application}-{profile}.properties
