The previous article wrote the first way to implement microservice architecture, and now the second way is still a fool
First blog link https://blog.csdn.net/qq_41684939/article/details/89602525
This is based on the last blog post
The registration center can see in the previous article
fegin implementation of microservice architecture

- Provider startup class
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);
}
}
- Provider 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;

@RestController
public class ServiceController {
@GetMapping("/hello")
public String hello() {
String s="Test open source framework fregin"+"This is service Layer: port="+"8814";
return s ;
}
}
- Startup success
7. Define consumers (directory structure)
8. yml configuration
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 # Enable Feign's support for Hystrix
compression:
request:
enabled: true # Turn on request compression
mime-types:
- text/xml
- application/xml
- application/json # Specify compression format
min-request-size: 2048 # The minimum threshold value of compression, 2048 by default, more than 2048 (bytes) for compression.
response:
enabled: true # Turn on compression of response
- Startup class
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);
}
}
- controller edit
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();
}
}
- Edit service
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();
}
- Start successful access
