springcloud fegin和rabbot分别实现微服务（二）

前面一篇文章 写了第一种 实现微服务架构 现在实现第二种 依然是傻瓜

第一篇博文链接 https://blog.csdn.net/qq_41684939/article/details/89602525

这是基于上一篇博文写的

fegin实现微服务架构

1. 提供者目录结构
   
2. 提供者uml

server:
   port: 8814 
  
eureka:
  client:
    serviceUrl:
      defaultZone: http://192.168.88.200:12345/eureka/

security:
  basic:
    enabled: false

spring: 
  application:
    name: service-fregin
    
    
feign:
  hystrix:
    enabled:  true  # 开启 Feign 对 Hystrix 的支持
  compression:
    request:
      enabled:  true   # 开启对 request 请求压缩
      mime-types:
        - text/xml
        - application/xml
        - application/json    # 指定压缩格式
      min-request-size: 2048  # 压缩的最小阀值，默认 2048，超过2048 （字节） 进行压缩。

    response:
      enabled:  true  # 开启对 response 的压缩
    

3. 提供者pom

4. 提供者启动类

package com.example.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.context.annotation.ComponentScan;

@SpringBootApplication
@EnableEurekaClient
@ComponentScan(basePackages = {"com.example"})
public class Demo1Application {

	public static void main(String[] args) {
		SpringApplication.run(Demo1Application.class, args);
	}

}

5. 提供者 controller

package com.example.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;


@RequestMapping("/fregin")
@RestController
public class ServiceController {

	
	 @GetMapping("/hello")
	    public String hello() {
	        String s="测试开源框架fregin"+"这是service层：port="+"8814";
	        return s ;
	    }


}

6. 启动成功

7. 定义 消费者（目录结构）

8. yml 配置

server:
   port: 8815 
  
eureka:
  client:
    serviceUrl:
      defaultZone: http://192.168.88.200:12345/eureka/

security:
  basic:
    enabled: false

spring: 
  application:
    name: service-fregin-server
feign:
  hystrix:
    enabled:  true  # 开启 Feign 对 Hystrix 的支持
  compression:
    request:
      enabled:  true   # 开启对 request 请求压缩
      mime-types:
        - text/xml
        - application/xml
        - application/json    # 指定压缩格式
      min-request-size: 2048  # 压缩的最小阀值，默认 2048，超过2048 （字节） 进行压缩。

    response:
      enabled:  true  # 开启对 response 的压缩
    

9. 启动类

package com.example.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.cloud.openfeign.EnableFeignClients;
import org.springframework.context.annotation.ComponentScan;

@SpringBootApplication
@EnableEurekaClient
@ComponentScan(basePackages = {"com.example"})
@EnableFeignClients(basePackages={"com.example.*"})
public class Demo1Application {

	public static void main(String[] args) {
		SpringApplication.run(Demo1Application.class, args);
	}

}

10. controller 编辑

package com.example.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;

import com.example.service.DemoService;


@RequestMapping("/freginServer")
@RestController
public class ServiceController {

	@Autowired
	DemoService service;
	
		@GetMapping("/hello")
	    public String hello() {
	       
			return service.hello();
	    }


}

11. serveice 编辑

package com.example.service;

import org.springframework.cloud.openfeign.FeignClient;
import org.springframework.stereotype.Service;
import org.springframework.web.bind.annotation.RequestMapping;

@FeignClient(value="service-fregin")
public interface DemoService {

	@RequestMapping("/fregin/hello")
	 String hello();
}

12. 启动成功 访问
