一、搭建Eureka集群

（1）创建2个Eureka微服务

（2）在两个模块中添加依赖

  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <project xmlns="http://maven.apache.org/POM/4.0.0"
  3.          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  4.          xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  5.     <parent>
  6.         <artifactId>springcloud</artifactId>
  7.         <groupId>com.buba</groupId>
  8.         <version>1.0-SNAPSHOT</version>
  9.     </parent>
  10.     <modelVersion>4.0.0</modelVersion>
  12.     <artifactId>springcloud-eureka-7002</artifactId>
  14.     <dependencies>
  15.         <dependency>
  16.             <groupId>org.springframework.cloud</groupId>
  17.             <artifactId>spring-cloud-starter-eureka-server</artifactId>
  18.             <version>1.4.7.RELEASE</version>
  19.         </dependency>
  20.         <!--        热部署工具-->
  21.         <dependency>
  22.             <groupId>org.springframework.boot</groupId>
  23.             <artifactId>spring-boot-devtools</artifactId>
  24.         </dependency>
  25.     </dependencies>
  26. </project>
  28. <?xml version="1.0" encoding="UTF-8"?>
  29. <project xmlns="http://maven.apache.org/POM/4.0.0"
  30.          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  31.          xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  32.     <parent>
  33.         <artifactId>springcloud</artifactId>
  34.         <groupId>com.buba</groupId>
  35.         <version>1.0-SNAPSHOT</version>
  36.     </parent>
  37.     <modelVersion>4.0.0</modelVersion>
  39.     <artifactId>springcloud-eureka-7003</artifactId>
  41.     <dependencies>
  42.         <dependency>
  43.             <groupId>org.springframework.cloud</groupId>
  44.             <artifactId>spring-cloud-starter-eureka-server</artifactId>
  45.             <version>1.4.7.RELEASE</version>
  46.         </dependency>
  47.         <!--        热部署工具-->
  48.         <dependency>
  49.             <groupId>org.springframework.boot</groupId>
  50.             <artifactId>spring-boot-devtools</artifactId>
  51.         </dependency>
  52.     </dependencies>
  53. </project>

（3）添加配置

watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQwMjk4MzUx_size_16_color_FFFFFF_t_70 2

（4）添加主启动类

  1. package com.buba.springcloud;
  3. import org.springframework.boot.SpringApplication;
  4. import org.springframework.boot.autoconfigure.SpringBootApplication;
  5. import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
  7. @SpringBootApplication
  8. @EnableEurekaServer // 服务端的启动类，可以接收别人注册进来
  9. public class EurekaServer_7002 {
  10.     public static void main(String[] args) {
  11.         SpringApplication.run(EurekaServer_7002.class, args);
  12.     }
  13. }
  15. package com.buba.springcloud;
  17. import org.springframework.boot.SpringApplication;
  18. import org.springframework.boot.autoconfigure.SpringBootApplication;
  19. import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
  21. @SpringBootApplication
  22. @EnableEurekaServer // 服务端的启动类，可以接收别人注册进来
  23. public class EurekaServer_7003 {
  24.     public static void main(String[] args) {
  25.         SpringApplication.run(EurekaServer_7003.class, args);
  26.     }
  27. }

（5）3个微服务互相绑定

模拟真实性，将本地域名同时映射3个网址

修改3个application.yml文件

watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQwMjk4MzUx_size_16_color_FFFFFF_t_70 7

（6）修改服务提供者模块，向3个Eureka都注册微服务

watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQwMjk4MzUx_size_16_color_FFFFFF_t_70 9

（7）启动测试

  1. 访问其中一个地址[http://localhost:7001/][http_localhost_7001]，可以看到另外2个进行了关联

  1. 启动服务提供者，可以看到3个Eureka中都有这个服务。
