springcloud 使用feign

一，被调用方 web-test

spring:
  application:
    name: web-test

二，web-test准备接口

package com.tenyears.webTest.controller;
 
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
 
@RestController
@RequestMapping("api/test")
public class TestController {
 
 
    @RequestMapping(value = "test1", method = RequestMethod.POST)
    public String test1() {
        return "hello";
    }
 
}

三，调用方web-hello

POM

<dependency>
      <groupId>org.springframework.cloud</groupId>
      <artifactId>spring-cloud-starter-feign</artifactId>
    </dependency>

四，Feign

@FeignClient(value="服务名")

package com.tenyears.webAD.feign;
 
import org.springframework.cloud.openfeign.FeignClient;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
 
/**
 * @description :
 * @auther Tyler
 * @date 2021/6/15
 */
 
@FeignClient(value = "web-test")
public interface WebTestFeign {
    @RequestMapping(value = "/api/test/test1", method = RequestMethod.POST)
    String test1();
}

Main方法添加 @EnableFeignClients

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

五，测试接口

package com.tenyears.webAD.controller;
 
import com.tenyears.webAD.feign.WebTestFeign;
import com.tenyears.webAD.service.service.AdScheduleService;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
 
/**
 * @author Tyler
 * @date 2019/4/16
 */
 
@RestController
@RequestMapping("api/test")
public class TestController {
    Logger logger = LoggerFactory.getLogger(TestController.class);
 
    @Autowired
    WebTestFeign webTestFeign;
 
 
    @RequestMapping(value = "test1", method = RequestMethod.POST)
    public String test1() {
        String str=webTestFeign.test1();
        return str;
    }
 
}
