1、复用服务注册中心

参考https://blog.csdn.net/chengyuqiang/article/details/90645498

spring.application.name=register-serverserver.port=8800eureka.client.register-with-eureka=falseeureka.client.fetch-registry=falseeureka.client.serviceUrl.defaultZone=http://localhost:8800/eureka/

2、改造config-server

2.1 pom.xml

添加

               
    
     org.springframework.cloud
                
    
     spring-cloud-starter-netflix-eureka-client
            
   

完整的pom.xml

   
       
    
     4.0.0
        
    
     com.cntaiping.tpa
        
    
     config-server
        
    
     0.0.1-SNAPSHOT
        
    
     jar
        
    
     config-server
        
    
     Demo project for Spring Boot
        
            
     
      com.cntaiping.tpa
             
     
      config
             
     
      1.0-SNAPSHOT
         
        
            
                 
      
       org.springframework.cloud
                  
      
       spring-cloud-starter-netflix-eureka-client
              
             
                 
      
       org.springframework.cloud
                  
      
       spring-cloud-config-server
              
             
                 
      
       mysql
                  
      
       mysql-connector-java
              
             
                 
      
       org.springframework.boot
                  
      
       spring-boot-starter-jdbc
              
         
    
   

2.2 application.yml

eureka:  client:    serviceUrl:      defaultZone: http://localhost:8800/eureka/spring:  profiles:    active: jdbc  application:    name: config-server  datasource:    url: jdbc:mysql://10.17.12.160:3306/config?useUnicode=true&characterEncoding=utf8&characterSetResults=utf8&serverTimezone=GMT%2B8    username: root    password: 123456    driver-class-name: com.mysql.jdbc.Driver  cloud:    config:      label: master      server:        jdbc: trueserver:  port: 8300spring.cloud.config.server.jdbc.sql: SELECT key1, value1 from config_properties where APPLICATION=? and PROFILE=? and LABEL=?

2.3 Application启动类

添加@EnableEurekaClient

package com.cntaiping.tpa.configserver;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;@SpringBootApplication@EnableConfigServer@EnableEurekaClientpublic class ConfigServerApplication {    public static void main(String[] args) {        SpringApplication.run(ConfigServerApplication.class, args);    }}

2.4 启动两个实例

3、改造config-client

3.1 pom.xml

   
       
    
     4.0.0
        
    
     com.cntaiping.tpa
        
    
     config-client
        
    
     0.0.1-SNAPSHOT
        
    
     jar
        
    
     config-client
        
    
     Demo project for Spring Boot
        
            
     
      com.cntaiping.tpa
             
     
      config
             
     
      1.0-SNAPSHOT
         
        
            
                 
      
       org.springframework.cloud
                  
      
       spring-cloud-starter-config
              
             
                 
      
       org.springframework.cloud
                  
      
       spring-cloud-starter-netflix-eureka-client
              
               
    
   

3.2 bootstrap.properties

spring.application.name=config-clienteureka.client.serviceUrl.defaultZone=http://localhost:8800/eureka/spring.profiles.active=dev#spring.cloud.config.uri= http://localhost:8300/spring.cloud.config.fail-fast=truespring.cloud.config.discovery.enabled=truespring.cloud.config.discovery.serviceId=config-serverserver.port=8083

3.3 Application类

package com.cntaiping.tpa.configclient;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.cloud.client.discovery.EnableDiscoveryClient;import org.springframework.cloud.netflix.eureka.EnableEurekaClient;@SpringBootApplication@EnableEurekaClient@EnableDiscoveryClientpublic class ConfigClientApplication {    public static void main(String[] args) {        SpringApplication.run(ConfigClientApplication.class, args);    }}

3、运行效果
