新建docker目錄
新建docker-compose.yml

version: "3.1"
services:
  cbj-api-admin:
      restart: always
      image: 192.168.0.39:5000/cbj-api-admin
      container_name: cbj-api-admin
      ports:
        - 8601:8601

新建Dockerfile

FROM openjdk:8-jre

MAINTAINER yuyingliang <[e-mail]>

RUN mkdir /app

COPY cbj-api-admin-1.0.0-SNAPSHOT.jar /app/app.jar

ENTRYPOINT [ "java", "-Djava.security.egd=file:/dev/./urandom", "-jar", "/app/app.jar","--spring.profiles.active=test"]

EXPOSE 8601

新建src/main/java
新建com.funtl.cbj.api.admin包
新建ApiAdminApplication啓動類

package com.funtl.cbj.api.admin;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.cloud.openfeign.EnableFeignClients;


@SpringBootApplication
@EnableDiscoveryClient
@EnableFeignClients
public class ApiAdminApplication {

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

}

新建service包
新建AdminService接口

package com.funtl.cbj.api.admin.service;

import com.funtl.cbj.api.admin.service.fallback.AdminServicefallback;
import org.springframework.cloud.openfeign.FeignClient;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;


@FeignClient(value = "cbj-service-admin",fallback = AdminServicefallback.class)
public interface AdminService {
    @RequestMapping(value = "login",method = RequestMethod.GET)
    public String login(@RequestParam(value="loginCode")String loginCode, @RequestParam(value = "password")String password);
}

新建fallback包在service下面
新建AdminServicefallback類

package com.funtl.cbj.api.admin.service.fallback;

import com.funt.cbj.common.constants.HttpStatusConstants;
import com.funt.cbj.common.dto.BaseResult;
import com.funt.cbj.common.utils.MapperUtils;
import com.funtl.cbj.api.admin.service.AdminService;
import com.google.common.collect.Lists;
import org.springframework.stereotype.Component;

@Component
public class AdminServicefallback implements AdminService{
    @Override
    public String login(String loginCode, String password) {

        BaseResult baseResult = BaseResult.notoOk(Lists.newArrayList(new BaseResult.Error(String.valueOf(HttpStatusConstants.BAD_GATEWAY.getStatus()), HttpStatusConstants.BAD_GATEWAY.getContent())));
        try {
            return MapperUtils.obj2json(baseResult);
        } catch (Exception e) {
            e.printStackTrace();
        }

        return  null;
    }
}

新建controller包
新建AdminController類

package com.funtl.cbj.api.admin.controller;

import com.funtl.cbj.api.admin.service.AdminService;
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;

@RestController

public class AdminController {
@Autowired
    AdminService adminService;
@RequestMapping(value = {"/login"},method = RequestMethod.GET)
public String login(){
    String json = adminService.login("yuyingliagn", "123456");
    System.out.println(json);
     return  json;
}


}
