在feign客户端接口中开启

@FeignClient("XXX")
public interface FeignIService {
@GetMapping("/memberIndex")
String feignIndex(@RequestParam("id") String id);
}

业务实现类使用feign客户端

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

import com.huahailong.service.impl.openfeign.MemberFeignService;

@RestController
public class OrderServiceImpl {

@Autowired
private FeignIService feignService;//feign客户端是默认post请求

@GetMapping("/orderToMember")
public String orderToMember(@RequestParam("id") String id) {
return feignService.feignIndex(id);
}
}

启动类配置

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.openfeign.EnableFeignClients;
import org.springframework.cloud.openfeign.FeignClient;

@EnableFeignClients//开启feign客户端
@SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
