一 、springboot整合eureka搭建注冊中心

二、springboot整合config搭建配置中心

三、從配置中心拉取配置

一 、springboot整合eureka搭建注冊中心

1、在IntelliJ IDEA中創(chuàng)建一個(gè)springboot項(xiàng)目，并命名為eureka

2、修改pom.xml，添加eureka-server的依賴

    <properties>

    </properties>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>
</project>

3、修改配置文件

server:
  port: 8761

eureka:
  instance:
    hostname: localhost # eureka所在的服務(wù)器名
  client:
    fetch-registry: false
    register-with-eureka: false
    # eureka提供服務(wù)的地址
    service-url:
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka

4、啟動(dòng)類上添加注解@EnableEurekaServer

package com.example.eureka;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

@EnableEurekaServer
@SpringBootApplication
public class Eureka {

    static final Logger logger = LoggerFactory.getLogger(Eureka.class);

    public static void main(String[] args) {
        if (logger.isDebugEnabled()) {
            logger.debug("啟動(dòng)eureka注冊中心......");
        }

        SpringApplication.run(EurekaApplication.class, args);
    }

}

5、啟動(dòng)項(xiàng)目

6、瀏覽器訪問localhost:8761，如果能看到下面的界面，說明eureka配置完成了

二、springboot整合config搭建配置中心

1、在IntelliJ IDEA中創(chuàng)建一個(gè)springboot項(xiàng)目，并命名為config

2、修改pom.xml，添加config-server的依賴

<?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 https://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.3.4.RELEASE</version>
        <relativePath/>
    </parent>

    <groupId>cn.edu.sgu.www</groupId>
    <artifactId>config</artifactId>
    <version>0.0.1-SNAPSHOT</version>

    <properties>
        <java.version>1.8</java.version>
        <eureka.version>1.4.4.RELEASE</eureka.version>
        <config.version>2.2.8.RELEASE</config.version>
    </properties>

    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Hoxton.SR12</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>

            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-eureka</artifactId>
                <version>${eureka.version}</version>
            </dependency>

            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-config-server</artifactId>
                <version>${config.version}</version>
            </dependency>
        </dependencies>
    </dependencyManagement>

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-eureka</artifactId>
        </dependency>

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

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>
</project>

4、修改配置文件，注冊到euraka并添加配置中心的配置

這里的配置文件可以存到當(dāng)前項(xiàng)目下，也可以存到git倉庫，還能保存到遠(yuǎn)程的服務(wù)器。

server:
  port: 8888

# 注冊到eureka
eureka:
  client:
    service-url:
      defaultZone: http://localhost:8761/eureka

spring:
  application:
    name: config-server
  cloud:
    config:
      server:
        # 本地
#        native:
#          searchLocations: classpath:/config #本地配置的路徑 讀取/resources/config下的配置
        # 遠(yuǎn)程git倉庫
        git:
          search-paths: config  # 配置文件所在根目錄
          uri: https://gitee.com/he-yunlin/repository.git # git倉庫地址

?5、啟動(dòng)類上添加注解@EnableConfigServer和@EnableEurekaClient

package cn.edu.sgu.www.config;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
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 Config {

    static final Logger logger = LoggerFactory.getLogger(Config.class);

    public static void main(String[] args) {
        if (logger.isDebugEnabled()) {
            logger.debug("啟動(dòng)config配置中心...");
        }

        SpringApplication.run(ConfigApplication.class, args);
    }

}

5、啟動(dòng)項(xiàng)目

6、瀏覽器訪問localhost:8761，查看服務(wù)config是否注冊到了eureka上

三、從配置中心拉取配置

經(jīng)過前面的兩步，已經(jīng)搭建好了配置中心，并且能夠正確的注冊到注冊中心，接下來創(chuàng)建一個(gè)服務(wù)，從配置中心拉取配置。

1、在IntelliJ IDEA中創(chuàng)建一個(gè)springboot項(xiàng)目eureka-client

2、添加maven依賴

<?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 https://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.3.4.RELEASE</version>
        <relativePath/>
    </parent>

    <groupId>com.example</groupId>
    <artifactId>euraka-client</artifactId>
    <version>0.0.1-SNAPSHOT</version>

    <properties>
        <java.version>1.8</java.version>
        <eureka.version>1.4.4.RELEASE</eureka.version>
        <config.version>2.2.8.RELEASE</config.version>
    </properties>

    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Hoxton.SR12</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>

            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-eureka</artifactId>
                <version>${eureka.version}</version>
            </dependency>

            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-config-client</artifactId>
                <version>${config.version}</version>
            </dependency>
        </dependencies>
    </dependencyManagement>

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-eureka</artifactId>
        </dependency>

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

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>
</project>

3、修改配置文件

server:
  port: 9001

spring:
  application:
    name: eureka-client
  profiles:
    active: dev
  cloud:
    config:
      profile: dev          # 不加此屬性直接獲取eureka-client.yml，加了后符合config的名字規(guī)則eureka-client-dev.yml
      enabled: true
      name: eureka-client   # 配置中心Git倉庫config文件夾里的文件名字
      label: master         # 默認(rèn)分支master
      fail-fast: true       # 是否啟動(dòng)快速失敗功能，功能開啟則優(yōu)先判斷config server是否正常
      discovery:
        enabled: true
        service-id: config-server  #spring cloud 配置中心服務(wù)名

eureka:
  instance:
    hostname: eureka
  client:
    service-url:
      defaultZone: http://localhost:8761/eureka

4、創(chuàng)建一個(gè)git倉庫，取名為repository，新建一個(gè)config包，在config包下新建一個(gè)eureka-client-dev.yml，配置項(xiàng)目的啟動(dòng)端口號

server:
  port: 9002

5、啟動(dòng)項(xiàng)目

如果最后項(xiàng)目啟動(dòng)的端口號不是9001，而是9002，說明成功拉取到了配置。
