Spring cloud--鸿鹄Cloud分布式微服务云系统—Config

Posted 2020-11-02

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">

    <parent>

    <build>

            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <executions>
                    <execution>
                        <id>1</id>
                        <goals>

    <execution>

    <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:[email protected]:8761/eureka/       honghuZone: http://honghu:[email protected]: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:[email protected]:8761/eureka/       honghuZone: http://honghu:[email protected]: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！！
