差异文件内容

 wly-config-dev.properties

local.ip=192.168.1.0 local.port=8080

 wly-config-test.properties

local.ip=192.168.1.1 local.port=8081

 wly-config-product.properties

local.ip=192.168.1.2 local.port=8082

 

spring boot版本：2.0.3.RELEASE

spring cloud config server配置

pom.xml

<dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-config-server</artifactId> </dependency>

 

application.yml

server: port: 8080 spring: application: name: spring-cloud-config-server-wly cloud: config: server: # git配置：项目/${search-paths}/${application}-${profile}.properties # cloud-config-wly/config/config/neo-config-dev.properties git: # 项目地址，换成自己的项目地址 uri: git@xxx:xxxx/cloud-config-wly.git # 表示文件路径 search-paths: config # 项目用户名，换成项目用户名 username: xxx # 项目密码，换成项目密码 password: xxx

 

启动类（新增@EnableConfigServer注解）

package com.wang.springcloudconfig; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.cloud.config.server.EnableConfigServer; @EnableConfigServer @SpringBootApplication public class SpringcloudconfigApplication { public static void main(String[] args) { SpringApplication.run(SpringcloudconfigApplication.class, args); } }

 

启动服务

http://localhost:8080/wly-config/dev

 

 

spring cloud config client配置

pom.xml

<!-- 引入spring cloud config 客户端配置 --> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-config</artifactId> </dependency> <!-- 引入web模块 --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency>

 

application.yml同级目录（src/main/resources）新增配置文件：bootstrap.properties

此文件会先于application.yml加载

# 相当于${application} spring.cloud.config.name=wly-config # 相当于${profile} spring.cloud.config.profile=product # 配置中心server服务url spring.cloud.config.uri=http://localhost:8080/ # 相当于git分支 spring.cloud.config.label=master

 

application.yml

spring: application: name: spring-cloud-config-client-wly server: port: 8081

 

controller

package com.wang.springcloudconfigclient.web; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.core.env.Environment; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; /** * @Author wly * @Date 2018/7/2 11:35 */ @RestController public class HelloController { @Autowired private Environment env; @RequestMapping("/test") public String test() { return env.getProperty("local.ip") + "," + env.getProperty("local.port"); } }

 访问

http://localhost:8081/test

页面输出

192.168.1.2,8082

 

基于注册中心版

在spring cloud config client端写死spring cloud config server的ip、port不适用于复杂多变的场景，比如集群的配置，ip变化等。所以我们可以基于注册中心配置

启动一个注册中心的服务spring-cloud-eureka，端口号8765

 

pom.xml

spring cloud config server、spring cloud config client均引入eureka客户端

<dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId> </dependency>

 

启动类

spring cloud config server、spring cloud config client启动类均添加注册注解（@EnableDiscoveryClient）

package com.wang.springcloudconfig; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.cloud.client.discovery.EnableDiscoveryClient; import org.springframework.cloud.config.server.EnableConfigServer; @EnableConfigServer @EnableDiscoveryClient @SpringBootApplication public class SpringcloudconfigApplication { public static void main(String[] args) { SpringApplication.run(SpringcloudconfigApplication.class, args); } }

 

spring cloud config server application.yml

添加注册中心配置

server: port: 8080 spring: application: name: spring-cloud-config-server-wly cloud: config: server: # git配置：项目/${search-paths}/${application}-${profile}.properties # cloud-config-wly/config/config/neo-config-dev.properties git: # 项目地址 uri: git@xxx:xxx/cloud-config-wly.git # 表示文件路径 search-paths: config # 项目用户名 username: xxxx # 项目密码 password: xxxx eureka: client: serviceUrl: defaultZone: http://localhost:8765/eureka

 

spring cloud config client bootstrap.properties

# 相当于${application} spring.cloud.config.name=wly-config # 相当于${profile} spring.cloud.config.profile=dev # 配置中心server服务url，使用注册中心配置后，此句注释即可 #spring.cloud.config.uri=http://localhost:8080/ # 相当于git分支 spring.cloud.config.label=master# 启用注册发现 spring.cloud.config.discovery.enabled=true# 读取服务，即config server的spring.application.name spring.cloud.config.discovery.serviceId=spring-cloud-config-server-wly # 注册中心地址 eureka.client.serviceUrl.defaultZone=http://localhost:8765/eureka

 

顺序启动注册中心、spring cloud config server、spring cloud config client3个服务

注册中心

访问（效果与之前一致~）

http://localhost:8080/wly-config/dev

http://localhost:8081/test
