Spring Cloud云服务架构 - commonservice-config配置服务搭建

1. 介绍

Spring Cloud Config为分布式系统中的外部配置提供服务器和客户端支持。使用Config Server，您可以在所有环境中管理应用程序的外部属性。客户端和服务器上的概念映射与Spring Environment和PropertySource抽象相同，因此它们与Spring应用程序非常契合，但可以与任何以任何语言运行的应用程序一起使用。随着应用程序通过从开发人员到测试和生产的部署流程，您可以管理这些环境之间的配置，并确定应用程序具有迁移时需要运行的一切。服务器存储后端的默认实现使用git，因此它轻松支持标签版本的配置环境，以及可以访问用于管理内容的各种工具。很容易添加替代实现，并使用Spring配置将其插入。

2. 引入pom相关jar包，其中pom.xml配置如下：

<?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>

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

            <scope>test</scope>
        </dependency>
    </dependencies>  

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>

                    <execution>
                        <id>1</id>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                                    <execution>
                                        <id>2</id>
                                            <goals>
                                                   <goal>build-info</goal>
                                            </goals>
                                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>
</project>

3. 在src/main/java进行ConfigApplication.java启动文件配置：

package com.ml.honghu;  

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.config.server.EnableConfigServer;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;  

@EnableConfigServer
@EnableEurekaClient
@SpringBootApplication
public class ConfigApplication {  

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

4. 在src/main/resource下进行bootstrap.yml配置

server:
port: 8888
spring:
  application:
    name: commonservice-config-server
  profiles:
    active: discovery,native
  cloud:
    config:
      server:
        git:
          uri: http://192.168.0.254/honghu.../honghu-config.git
          username: honghu
          password: 123456
          searchPaths: config-dev
security:
  basic:
    enabled: true
  user:
    name: honghu
    password: 123456
eureka:
  client:
    serviceUrl:
      defaultZone: http://honghu:123456@localhost:8761/eureka/
      honghuZone: http://honghu:123456@localhost:8761/eureka/
    registry-fetch-interval-seconds: 300
    availability-zones:
      honghu: honghuZone
  instance:
    prefer-ip-address: true
    metadataMap:
      version: 1.0
      variant: A
      user: ${security.user.name}
      password: ${security.user.password}
management:
  security:
    enabled: false

注意： 如果不从远程git或者svn库加载配置文件信息，可以配置加载本地地址，比如window下配置使用：

server:
port: 8888
spring:
  application:
    name: commonservice-config-server
  profiles:
    active: discovery,native
  cloud:
    config:
      server:
        <span style="color: #ff0000;">native.searchLocations: d:/honghu-config</span>
security:
  basic:
    enabled: true
  user:
    name: honghu
    password: 123456
eureka:
  client:
    serviceUrl:
      defaultZone: http://honghu:123456@localhost:8761/eureka/
      honghuZone: http://honghu:123456@localhost:8761/eureka/
    registry-fetch-interval-seconds: 300
    availability-zones:
      honghu: honghuZone
  instance:
    prefer-ip-address: true
    metadataMap:
      version: 1.0
      variant: A
      user: ${security.user.name}
      password: ${security.user.password}
management:
  security:
    enabled: false

到此，整个config服务项目配置完毕！！
