一、引入依赖

implementation 'io.github.openfeign:feign-core:11.0'
implementation 'com.netflix.feign:feign-jackson:8.18.0'

二、客户端接口类 MyFeignClient

package com.fdw.study.feign;import com.fdw.study.validate.User;
import feign.RequestLine;
import org.springframework.web.bind.annotation.RequestBody;/*** @program: hibbernatestudy* @description: 脱离springCloud使用Feign* @author:* @create: 2023-12-22 15:43**/
public interface MyFeignClient {@RequestLine("POST /feign-test")User getUserByfeign(@RequestBody String id);
}

三、客户端调用服务类

FeignService：

package com.fdw.study.feign;import com.fdw.study.validate.User;public interface FeignService {public User getUser(String id);
}

FeignServiceImpl：

package com.fdw.study.feign;imp
