1. 配置註冊中心的Maven的pom檔案

 <!--設定登入密碼需要用到Spring Security-->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-security</artifactId>
</dependency>

2. 配置註冊中心的application.yml

server:
  port: 8761
  
#設定eurekaServer的登入密碼
 

spring:
  security:
    user:
      name: admin  # 使用者名稱
      password: admin   # 使用者密碼

eureka:
  instance:
    hostname: localhost
  client:
    registerWithEureka: false #不向eurekaServer註冊   因為自己就是server
    fetchRegistry: false      #不獲取註冊中心的服務     因為自己就是server
    serviceUrl:
      defaultZone
 
: http://${eureka.instance.hostname}:${server.port}/eureka/   #服務註冊中心的位置

3. 註冊中心關閉Spring Security的CSRF驗證

package com.wind.eurekaserver;

import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.
 
security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;

/**
 1. 如果eurekaServer設定了登入密碼   就必須關閉Spring Security的CSRF驗證
 */
@EnableWebSecurity
@Configuration
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable(); //關閉csrf
        super.configure(http);
    }
}

如果不關閉，那麼客戶端就連線不上

4. 配置Client的application.yml

server:
    port: 8762

spring:
    application:
        name: eureka-client   #配置在eurekaServer中註冊的名字

eureka:
    instance:
        prefer-ip-address: true   #在eurekaServer中服務地址以ip顯示
    client:
        serviceUrl:
            #defaultZone: http://localhost:8761/eureka/   #設定eurekaServer的uri
            defaultZone: http://admin:[email protected]:8761/eureka/    #eurekaServer設定了登入驗證

此時就大功告成了
