post返回集合方式：

List<Integer> mlIds = memberLabelList.stream().map(MemberLabel::getId).collect(Collectors.toList());
    HttpHeaders httpHeaders = new HttpHeaders();
    httpHeaders.setContentType(MediaType.APPLICATION_JSON);
    Map<String, Object> map = new HashMap<>();
    map.put("ids",mlIds);
    HttpEntity<Map<String, Object>> httpEntity = new HttpEntity<>(map,httpHeaders);
    ResponseEntity<MemberLabelRuleVo[]> response = restTemplate.postForEntity(mmlUrl, map, MemberLabelRuleVo[].class);

cotroller  :

@RequestMapping(value = "/queryMemberLabelRuleByIds", method = RequestMethod.POST)
    public List<MemberLabelRuleVo> queryMemberLabelRuleByIds(@RequestBody Map<String,Object> map) {
        List<Integer> ids = new ArrayList<>();
        Object objIds = map.get("ids");
        String listStr = JSONObject.toJSONString(objIds);
        ids = JSONObject.parseArray(listStr,Integer.class);
        List<MemberLabelRule> memberLabelRules = memberLabelRuleService.queryMemberLabelRuleByIds(ids);
        List<MemberLabelRuleVo> memberLabelRuleVoList = new ArrayList<>();
        if (ObjectUtils.isNotEmpty(memberLabelRules)) {
            memberLabelRules.forEach((mlr)->{
                MemberLabelRuleVo memberLabelRuleVo = new MemberLabelRuleVo();
                BeanUtils.copyProperties(mlr,memberLabelRuleVo);
                memberLabelRuleVoList.add(memberLabelRuleVo);
            });
        }
        return memberLabelRuleVoList;
    }
