嗨,我最近学习了spring cloud with feign client和Eureka ,但是在打开我的web应用程序时遇到了麻烦。
FeignException$NotFound:状态404阅读RoomReservationService#getRoomReservationsForDate(String)
and The error at com.frankmoley.webapp.reservation.ReservationController.getReservations(ReservationController.java:42)
这里是我的代码RoomReservationService

package com.frankmoley.webapp.reservation.client;

import com.frankmoley.webapp.reservation.domain.Room;
import com.frankmoley.webapp.reservation.domain.RoomReservation;
import org.springframework.cloud.openfeign.FeignClient;
import org.springframework.stereotype.Component;
import org.springframework.stereotype.Repository;
import org.springframework.stereotype.Service;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;

import java.util.List;

/**
 * Created by frankmoley on 5/23/17.
 */

@FeignClient("RESERVATIONBUSINESSSERVICES")
public interface RoomReservationService {

    @RequestMapping(value = "/rooms", method = RequestMethod.GET)
    public List<Room> getAllRooms(@RequestParam(name="roomNumber", required=false)String roomNumber);

    @RequestMapping(value="/roomReservations/{date}", method=RequestMethod.GET)
    public List<RoomReservation> getRoomReservationsForDate(@PathVariable("date") String date);
}

字符串
和我的ReservationController

package com.frankmoley.webapp.reservation;

import com.frankmoley.webapp.reservation.client.RoomReservationService;
import com.frankmoley.webapp.reservation.domain.Room;
import com.frankmoley.webapp.reservation.domain.RoomReservation;

import io.micrometer.core.instrument.util.StringUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;

import java.util.Date;
import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.List;

@Controller
@RequestMapping(value="/reservations")
public class ReservationController {

    private static final DateFormat DATE_FORMAT = new SimpleDateFormat("yyyy-MM-dd");

    private final RoomReservationService roomReservationService;

    @Autowired
    public ReservationController(RoomReservationService roomReservationService){
        super();
        this.roomReservationService = roomReservationService;
    }

    @RequestMapping(method= RequestMethod.GET)
    public String getReservations(@RequestParam(value="date", required=false)String dateString, Model model){
        String date = dateString;
        if(StringUtils.isBlank(dateString)){
            date = this.createTodayDateString();
        }
        List<Room> rooms = this.roomReservationService.getAllRooms("P1");
        List<RoomReservation> roomReservations = this.roomReservationService.getRoomReservationsForDate(date);
        model.addAttribute("roomReservations", roomReservations);
        return "reservations";
    }

    public String createTodayDateString(){
        return DATE_FORMAT.format(new Date());
    }
}


我一直在寻找任何地方,但无法找到答案,请帮助我

由于它是404,它找不到配置客户端的URL。看起来你需要为假客户端配置URL。配置可以通过应用程序yaml的
例如,应用程序.yaml

RESERVATIONBUSINESSSERVICES: 
                         url: http:localhost:8080/reservationbusinessservice/

字符串
客房预订服务

@FeignClient(name = "RESERVATIONBUSINESSSERVICES", url = "${RESERVATIONBUSINESSSERVICES.url}",

你是否使用servlet上下文路径,如果你使用它,你需要在Feign Client方法中包含上下文路径
