Spring Cloud Config 配置中心

1.构建config-server

创建一个pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.bennytitan</groupId><artifactId>config-server</artifactId><version>0.0.1-SNAPSHOT</version><packaging>jar</packaging><name>config-server</name><description>Demo project for Spring Boot</description><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.0.0.RELEASE</version><relativePath/> <!-- lookup parent from repository --></parent><properties><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding><java.version>1.8</java.version><spring-cloud.version>Finchley.RELEASE</spring-cloud.version></properties><dependencies><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-netflix-eureka-client</artifactId></dependency><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-config-server</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency><!-- 新增依赖 --><dependency><groupId>com.fasterxml</groupId><artifactId>classmate</artifactId><version>1.4.0</version></dependency></dependencies><dependencyManagement><dependencies><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-dependencies</artifactId><version>${spring-cloud.version}</version><type>pom</type><scope>import</scope></dependency></dependencies></dependencyManagement><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin></plugins></build><repositories><repository><id>public</id><name>aliyun nexus</name><url>http://maven.aliyun.com/nexus/content/groups/public/</url><releases><enabled>true</enabled></releases></repository></repositories><pluginRepositories><pluginRepository><id>public</id><name>aliyun nexus</name><url>http://maven.aliyun.com/nexus/content/groups/public/</url><releases><enabled>true</enabled></releases><snapshots><enabled>false</enabled></snapshots></pluginRepository></pluginRepositories></project>

ConfigServerApplication.java

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

application.properties

spring.application.name=config-server
server.port=8888eureka.client.serviceUrl.defaultZone=http://localhost:8761/eureka/
#spring.cloud.config.server.git.uri=https://gitee.com/JeeGemEdu/SpringCloudConfig/
spring.cloud.config.server.git.uri=https://github.com/forezp/SpringcloudConfig/
spring.cloud.config.server.git.searchPaths=respo
spring.cloud.config.label=master
spring.cloud.config.server.git.username=
spring.cloud.config.server.git.password=

启动服务，浏览器输入http://localhost:8888/foo/dev，得到下图结果表示config状态正常，可以远程取用配置文件了

http请求地址和资源文件映射如下:

/{application}/{profile}[/{label}]
/{application}-{profile}.yml
/{label}/{application}-{profile}.yml
/{application}-{profile}.properties
/{label}/{application}-{profile}.properties

2.构建一个config client

pom.xml:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.bennytitan</groupId><artifactId>config-client</artifactId><version>0.0.1-SNAPSHOT</version><packaging>jar</packaging><name>config-client</name><description>Demo project for Spring Boot</description><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.0.0.RELEASE</version><relativePath/> <!-- lookup parent from repository --></parent><properties><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding><java.version>1.8</java.version><spring-cloud.version>Finchley.RELEASE</spring-cloud.version></properties><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-config</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency><!-- 新增依赖 --><dependency><groupId>com.fasterxml</groupId><artifactId>classmate</artifactId><version>1.4.0</version></dependency></dependencies><dependencyManagement><dependencies><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-dependencies</artifactId><version>${spring-cloud.version}</version><type>pom</type><scope>import</scope></dependency></dependencies></dependencyManagement><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin></plugins></build><repositories><repository><id>public</id><name>aliyun nexus</name><url>http://maven.aliyun.com/nexus/content/groups/public/</url><releases><enabled>true</enabled></releases></repository></repositories><pluginRepositories><pluginRepository><id>public</id><name>aliyun nexus</name><url>http://maven.aliyun.com/nexus/content/groups/public/</url><releases><enabled>true</enabled></releases><snapshots><enabled>false</enabled></snapshots></pluginRepository></pluginRepositories></project>

ConfigClientApplication.java

package com.bennytitan.configclient;

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;

@SpringBootApplication@RestControllerpublic class ConfigClientApplication {

    public static void main(String[] args) {        SpringApplication.run(ConfigClientApplication.class, args);    }

    @Value("${foo}")    String foo;    @RequestMapping(value = "/hi")    public String hi(){        return foo;    }}

application.properties

spring.application.name=config-client
spring.cloud.config.label=master
spring.cloud.config.profile=dev
spring.cloud.config.uri= http://localhost:8888/
server.port=8881

打开网址访问：http://localhost:8881/hi，网页显示：

3.高可用分布式配置

上面的config-server已经配置好了，如果可以，可以启动多个config-server。

主要是改造config-client的pom.xml增加客户端服务管理：

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

然后application.properties的配置如下，这里都不需要指定config-server的IP地址，直接通过服务ID就能获取到了：

spring.application.name=config-client
spring.cloud.config.label=master
spring.cloud.config.profile=dev
#spring.cloud.config.uri= http://localhost:8888/eureka.client.serviceUrl.defaultZone=http://localhost:8761/eureka/
spring.cloud.config.discovery.enabled=true
spring.cloud.config.discovery.serviceId=config-server
server.port=8881

测试，访问http://localhost:8881/hi，浏览器显示：
