springcloud分布式配置中心

一共三个部分  

1、注册中心

配置文件：application.yml

###服务启动端口号
server:
  port: 8100
###服务名称(服务注册到eureka名称)
spring:
  application:
    name: server
###服务注册到eureka地址
eureka:
  client:
    service-url:
      defaultZone: http://localhost:8100/eureka


    ###由于该应用为注册中心，不会注册本身
    register-with-eureka: true
    ###是否须要从eureka上获取注册信息
    fetch-registry: true

启动类

@EnableEurekaServer
@SpringBootApplication
public class springcloudEureka {
    public static void main(String[] args) {
        SpringApplication.run(springcloudEureka.class,args);
    }
}

pom文件

		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>2.0.1.RELEASE</version>
	</parent>

			<snapshots>

			</snapshots>
		</repository>
	</repositories>

2、configServer

1、配置文件 ：bootstrap.yml

###服务注册到eureka地址
eureka:
  client:
    service-url:
      defaultZone: http://localhost:8100/eureka
spring:
  application:
    ####注册中心应用名称
    name: config
  cloud:
    config:
      server:
        git:
          .
          ###git环境地址
          uri: https://gitee.com/XXXX/testspringcloud.git
          ####svn项目下属搜索目录
          search-paths:
          - testspringcloud
          ###帐号密码
          username: XXXXX
          password: XXXXX
      ####读取分支
      label: master
####端口号
server:
  port: 9999

2、启动类

@EnableConfigServer//开启配置中心
@SpringBootApplication
@EnableEurekaClient
public class Star {

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

}

pom文件

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.1.RELEASE</version>
    </parent>  
<!-- 管理依赖 -->
    <dependencyManagement>

            </dependency>
        </dependencies>
    </dependencyManagement>
    <dependencies>
        <!--spring-cloud 整合 config-server -->
        <dependency>

            <artifactId>spring-cloud-config-server</artifactId>
            <version>2.1.2.RELEASE</version>
        </dependency>

        <!-- SpringBoot整合eureka客户端 -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>

    </dependencies>
    <!-- 注意： 这里必需要添加， 否者各类依赖有问题 -->
    <repositories>
        <repository>
            <id>spring-milestones</id>
            <name>Spring Milestones</name>
            <url>https://repo.spring.io/libs-milestone</url>
            <snapshots>
                <enabled>false</enabled>
            </snapshots>
        </repository>
    </repositories>

测试有没有配置成功浏览器输出：

3、configclient

1、配置文件 bootstrap.yml

spring:
  application:
    ####与git上配置文件前缀同样
    name:  config
  cloud:
    config:
      ####读取后缀
      profile: sit
      ####读取config-server注册地址
      discovery:
        ##与configServer在注册中心上别名同样
        serviceId: config
        enabled: true
      label: master
     # uri: http://localhost:9999/
#####    eureka服务注册地址
eureka:
  client:
    service-url:
      defaultZone: http://localhost:8100/eureka
server:
  port: 8882

2、启动类

@SpringBootApplication
@EnableEurekaClient
public class Star {

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

}
