简介
Spring cloud config 分为两部分 server client
- config-server 配置服务端，服务管理配置信息
- config-client 客户端，客户端调用server端暴露接口获取配置信息
config-server
创建config-server
首先创建工程.
文件结构：
├── config-server.iml├── pom.xml└── src ├── main │ ├── java │ │ └── com │ │ └── lkl │ │ └── springcloud │ │ └── config │ │ └── server │ │ └── Application.java │ └── resources │ ├── application.properties │ └── bootstrap.properties └── test └── java
pom.xml内容：
4.0.0 org.springframework.boot spring-boot-starter-parent 1.2.3.RELEASE com.lkl.springcloud spring-cloud-config-server 1.0-SNAPSHOT org.springframework.cloud spring-cloud-config 1.0.4.RELEASE pom import org.springframework.cloud spring-cloud-starter-config org.springframework.boot spring-boot-starter-web org.springframework.boot spring-boot-starter-actuator org.springframework.cloud spring-cloud-config-server org.springframework.boot spring-boot-maven-plugin
创建启动类
Application. package com.lkl.springcloud.config.server;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.EnableAutoConfiguration;import org.springframework.cloud.config.server.EnableConfigServer;import org.springframework.context.annotation.Configuration; import org.springframework.web.bind.annotation.RestController; /** * Created by liaokailin on 16/4/28. */ @Configuration @EnableAutoConfiguration @RestController @EnableConfigServer public class Application { public static void main(String[] args) { SpringApplication.run(Application.class, args); } }
其中 @EnableConfigServer为关键注解
在resources文件下创建application.properties
server.port=8888
- application:表示应用名称,在client中通过
spring.config.name配置 - profile:表示获取指定环境下配置，例如开发环境、测试环境、生产环境 默认值default，实际开发中可以是 dev、test、demo、production等
- label: git标签，默认值master
如果application名称为foo，则可以采用如下方式访问：
只要是按照上面的规则配置即可访问.
config-client
创建config-client
目录结构如下：
├── pom.xml├── spring-cloud-config-client.iml└── src ├── main │ ├── java │ │ └── com │ │ └── lkl │ │ └── springcloud │ │ └── config │ │ └── client │ │ └── Application.java │ └── resources │ └── bootstrap.yml └── test └── java
pom.xml
4.0.0 com.lkl.springcloud spring-cloud-config-client 1.0-SNAPSHOT org.springframework.boot spring-boot-starter-parent 1.2.3.RELEASE org.springframework.cloud spring-cloud-starter-parent 1.0.1.RELEASE pom import org.springframework.boot spring-boot-starter-web org.springframework.cloud spring-cloud-config-client org.springframework.boot spring-boot-starter-actuator org.springframework.boot spring-boot-starter-test test spring-milestones Spring Milestones http://repo.spring.io/milestone false spring-milestones Spring Milestones http://repo.spring.io/milestone false org.springframework.boot spring-boot-maven-plugin
创建启动类Application.java
package com.lkl.springcloud.config.client;import org.springframework.beans.factory.annotation.Value;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; /** * Created by liaokailin on 16/4/28. */ @SpringBootApplication @RestController public class Application { @Value("${name:World!}") String bar; @RequestMapping("/") String hello() { return "Hello " + bar + "!"; } public static void main(String[] args) { SpringApplication.run(Application.class, args); } }
创建bootstrap.properties文件，其内容如下：
spring.application.name: foospring.cloud.config.env:defaultspring.cloud.config.label:master spring.cloud.config.uri:http://localhost:8888
其中 spring.application.name 为应用名称，spring.cloud.config.uri 配置config-server暴露的获取配置接口,其默认值为http://localhost:8888
bootstrap.properties只需要配置应用名即可. 运行
访问 http://localhost 得到 `Hello liaokailin` 获取到git上的配置信息访问 http://localhost/env 得到所有的配置信息，可以发现获取配置信息成功.
{profiles: [ ],configService:https://github.com/liaokailin/config-repo/foo.properties: {name: "liaokailin", foo: "devoxxfr" }, configService:https://github.com/liaokailin/config-repo/application.yml: { info.description: "Spring Cloud Samples--lkl", info.url: "https://github.com/spring-cloud-samples", eureka.client.serviceUrl.defaultZone: "http://localhost:8761/eureka/" }, commandLineArgs: { spring.output.ansi.enabled: "always" }, servletContextInitParams: { }, ...}
