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代码
<?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:
Java代码
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
Java代码
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:
Java代码
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!!(企业架构源码可以加求球:叁五三陆二肆柒二伍玖)
