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

結果始終為linkedHashMap？？？

解決方法：

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

ResponseEntity<List<QcReportbillNc>> exchange = restTemplate()
        .exchange("http://127.0.0.1:8080/getNC?createTime="
 
+qcReportbillNcVo.getCreateTime()+"&code="
+qcReportbillNcVo.getCode()+"&workshopPK="
+qcReportbillNcVo.getWorkshopPK()+"&times="
+qcReportbillNcVo.getTimes(),
HttpMethod.GET, null, new ParameterizedTypeReference<List<QcReportbillNc>>(){});
if (exchange.getStatusCode() == HttpStatus.OK
 
) {
    return exchange.getBody();
}

List<QcReportbillNc> nclist = exchange.getBody()
