restTemplate 发送post请求

test端：

接收端：

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;
