被调用的 application service

import io.github.jihch.pojo.People;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.ArrayList;
import java.util.List;
import java.util.Map;

@RestController
public class DemoController {

    @RequestMapping("/demo3/{name}/{age}")
    public String demo3(@PathVariable String name, @PathVariable Integer age) {
        return "name:" + name + ",age:" + age;
    }

}

调用方 application client

ServiceDemoFeign.java

package io.github.jihch.feign;

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

@FeignClient("MYPROJECT")
public interface ServiceDemoFeign {

    @RequestMapping("/demo3/{jqk}/{abc}")
    String suiyi3(@RequestParam String jqk, @RequestParam Integer age);

}

下面这么写也是可以的:

    @RequestMapping("/demo3/{jqk}/{abc}")
    String suiyi3(@PathVariable String jqk, @PathVariable Integer abc);

FeignDemoService.java

package io.github.jihch.service;
public interface FeignDemoService {

    String demo3(String name, Integer age);

}

FeignDemoServiceImpl.java

package io.github.jihch.service.impl;

import io.github.jihch.feign.ServiceDemoFeign;
import io.github.jihch.service.FeignDemoService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

@Service
public class FeignDemoServiceImpl implements FeignDemoService {

    @Autowired
    private ServiceDemoFeign serviceDemoFeign;

    @Override
    public String demo3(String name, Integer age) {
        return serviceDemoFeign.suiyi3(name, age);
    }

}

FeignDemoController.java

package io.github.jihch.controller;

import io.github.jihch.service.FeignDemoService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class FeignDemoController {

    @Autowired
    private FeignDemoService feignDemoService;


    @RequestMapping("/demo3")
    public String demo3() {
        return feignDemoService.demo3("张三", 88);
    }


}
