将

@Bean
        public RestTemplate restTemplate(RestTemplateBuilder builder) {
            RestTemplate restTemplate = builder.build();
            return restTemplate;
        }

改为

@Bean
        public RestTemplate restTemplate(RestTemplateBuilder builder) {
            RestTemplate restTemplate = builder.build();
            restTemplate.setErrorHandler(new RtErrorHandler());
            return restTemplate;
        }

*  RtErrorHandler 白名单上的异常则不处理，直接返回
 *      package cn.linksign.supervise.exception;
        
        import org.springframework.http.HttpStatus;
        import org.springframework.http.client.ClientHttpResponse;
        import org.springframework.web.client.DefaultResponseErrorHandler;
        
        import java.io.IOException;
        import java.util.ArrayList;
        import java.util.List;
        
        /**
         * 功能：捕获RestTemplate异常
         *
         */
        public class RtErrorHandler extends DefaultResponseErrorHandler {
        
            @Override
            public boolean hasError(ClientHttpResponse response) throws IOException {
                return super.hasError(response);
            }
        
            @Override
            public void handleError(ClientHttpResponse response) throws IOException {
                HttpStatus statusCode = HttpStatus.resolve(response.getRawStatusCode());
                List<HttpStatus> donotDeal = new ArrayList<>(); // 白名单
                donotDeal.add(HttpStatus.UNAUTHORIZED);
        
                if (!donotDeal.contains(statusCode)) { // 非白名单则处理
                    super.handleError(response);
                }
            }
        
        }
