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SpringEnvironment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> <parent> <groupId>com.ml.honghu</groupId> <artifactId>commonservice</artifactId> <version>0.0.1-SNAPSHOT</version> </parent> <artifactId>commonservice-config</artifactId> <packaging>jar</packaging> <name>commonservice-config</name> <description>Config Server</description> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-config-server</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-eureka</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-security</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <executions> <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！！
