smilodon

简介

smilodon中文是剑齿虎，是一套服务注册发现工具包，实现的目的是更好了解微服务的原理，实现spring-cloud-commons部分功能，支持@LoadBalanced注解，可以使用RestTemplate调用服务

smilodon服务器

配置smilodon服务器

• 先决条件
  • JDK 1.8或更高
  • springboot 2.3或更高
  • springcloud Hoxton.SR8或更高
• maven 依赖

  <dependency>
      <groupId>cn.lilq.smilodon</groupId>
      <artifactId>smilodon-server-spring-boot-starter</artifactId>
      <version>0.2.4</version>
  </dependency>

构建smilodon服务器

• 启用smilodon服务器

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

• 可选配置

  smilodon.instance.prefer-ip-address=true
  smilodon.instance.hostname=127.0.0.1
  smilodon.server.max-wait-time=60
  smilodon.server.testing-time=20

smilodon客户端

配置smilodon客户端

• 先决条件
  • JDK 1.8或更高
  • springboot 2.3或更高
  • springcloud Hoxton.SR8或更高
• maven 依赖

  <dependency>
      <groupId>cn.lilq.smilodon</groupId>
      <artifactId>smilodon-client-spring-boot-starter</artifactId>
      <version>0.2.4</version>
  </dependency>

构建smilodon客户端

• 启用smilodon服务器

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

• 可选配置

  smilodon.instance.prefer-ip-address=true
  smilodon.instance.instance-id=ordersys5001
  smilodon.client.fetch-registry=false
  #smilodon.client.fetch-registry=true
  smilodon.client.service-url=http://localhost:7010
  #smilodon.client.register-with-smilodon=false
  smilodon.client.register-with-smilodon=true

• 使用discoveryClient进行服务发现

  @Resource
  private DiscoveryClient discoveryClient;
  
  @ResponseBody
  @RequestMapping(value = "/",method = RequestMethod.GET)
  public void getServices(){
      System.out.println(discoveryClient.getServices());
  }
  
  @ResponseBody
  @RequestMapping(value = "/{id}",method = RequestMethod.GET)
  public void getInstances(@PathVariable String id){
      System.out.println(discoveryClient.getInstances(id));
  }

• 使用具有@LoadBalanced注解的RestTemplate调用服务

  @ResponseBody
  @RequestMapping(value = "/hello", method = RequestMethod.GET)
  public Response hello() {
      return new Response(200,"successful","hello world,port:"+serverPort);
  }
  
  @ResponseBody
  @RequestMapping(value = "/sayhello", method = RequestMethod.GET)
  public Response sayHello() {
      Response response = restTemplate.getForObject("http://ORDER-SERVER/hello", Response.class);
      System.out.println(response);
      return response;
  }
  
  @Bean
  @LoadBalanced
  public RestTemplate restTemplate() {
      return new RestTemplate();
  }

演示

• test地址

不足

• 动态注入controller
• 心跳检测
• 订阅controller 动态注入 (注入异常)
