feign调用第三方接口,编码定义GBK,响应中文乱码处理方式

@FeignClient(value="{}",configuration=FeignClientLogConfiguration.class, contextId="id")
public interface FeignClient{
    @PostMapping(value="/test", headers={"Content-Type=application/json;charset=gbk"})
    String test(String req);
}

@Autowired
FeignClient feignClient;
public void getTest(请求实体类 req){
    String jsonReq = JSON.toJSONString(req);
    String resp = feignClient.test(jsonReq);
    log.info("响应报文：{}", resp);// 日志打印出来中文乱码
}

import feign.Response;
 
@FeignClient(value="{}",configuration=FeignClientLogConfiguration.class, contextId="id")
public interface FeignClient{
    @PostMapping(value="/test", headers={"Content-Type=application/json;charset=gbk"})
    Response test(String req);
}

@Autowired
FeignClient feignClient;
public void getTest(请求实体类 req){
    String jsonReq = JSON.toJSONString(req);
    Response resp = feignClient.test(jsonReq);
    String resp = this.printToRespInfo(resp);
    log.info("响应报文：{}", resp);// 日志打印出来中文乱码
}
