ResponseEntity exchange = restTemplate().exchange("http://127.0.0.1:8080", HttpMethod.GET, entity,List.class)    ;

解决方法：

@Bean
@LoadBalanced
RestTemplate restTemplate() {
    return new RestTemplate();
}

ResponseEntity> exchange = restTemplate()
        .exchange("http://127.0.0.1:8080/getNC?createTime="
                        +qcReportbillNcVo.getCreateTime()+"&code="
                        +qcReportbillNcVo.getCode()+"&workshopPK="
                        +qcReportbillNcVo.getWorkshopPK()+"×="
                        +qcReportbillNcVo.getTimes(),
                HttpMethod.GET, null, new ParameterizedTypeReference>(){});

if (exchange.getStatusCode() == HttpStatus.OK) {
    return exchange.getBody();
}

List nclist = exchange.getBody()
