搭建eureka-server

创建一个子模块用来搭建eureka-server

依赖:

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

给eureka-server服务编写一个启动类，一定要添加一个@EnableEurekaServer注解，开启eureka的注册中心功能

配置文件中写:

server:
  port: 10086
spring:
  application:
    name: eureka-server
eureka:
  client:
    service-url: 
      defaultZone: http://127.0.0.1:10086/eureka

服务端完成

服务注册:

先导入依赖:

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

配置文件中写:

spring:
  application:
    name: userservice
eureka:
  client:
    service-url:
      defaultZone: http://127.0.0.1:10086/eureka

服务发现:

先导入依赖

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

配置文件

spring:
  application:
    name: orderservice
eureka:
  client:
    service-url:
      defaultZone: http://127.0.0.1:10086/eureka

在order-service的OrderApplication中，给RestTemplate这个Bean添加一个@LoadBalanced注解
