【Spring Cloud】服务生产者

创建spring boot项目并添加依赖

创建项目过程略

添加依赖

<!-- 用于进行WEB开发，向外提供服务接口-->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>
<!-- 添加spring cloud eureka-client-->
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>

服务配置

• application.yml

  spring:
    application:
      name: service-producter
  server:
    port: 8081
  eureka:
    client:
      service-url:
        defaultZone: http://localhost:8000/eureka/ //对应服务注册中心的配置，指定服务注册中心地址
  

• 启动类添加注解@EnableEurekaClient

  @EnableEurekaClient
  @SpringBootApplication
  public class ServiceProductApplication {
      public static void main(String[] args) {
          SpringApplication.run(ServiceProductApplication.class, args);
      }
  }
  

添加服务接口

/user/

• 创建UserController

  package com.icodesoft.serviceproducter.controller;
  
  import org.springframework.web.bind.annotation.GetMapping;
  import org.springframework.web.bind.annotation.PathVariable;
  import org.springframework.web.bind.annotation.RequestMapping;
  import org.springframework.web.bind.annotation.RestController;
  
  @RestController
  @RequestMapping("/user")
  public class UserController {
      @GetMapping("/{id}")
      public String getUserNameById(@PathVariable("id") String id) {
          return "name: gary, id: " + id;
      }
  }
  

运行结果

• 测试接口

  http://localhost:8081/user/124

  

• 服务中心
