restTemplate使用

  HttpHeaders httpHeaders = new HttpHeaders();
        httpHeaders.set("access-token", "abc123");

        ParamVO paramVO= new ParamVO();
        paramVO.setCurrentPage(1);
        paramVO.setPageSize(10);
        
HttpEntity entity = new HttpEntity(paramVO,httpHeaders);
            ResponseEntity<String> result = restTemplate.exchange(url,
                    HttpMethod.POST,
                    entity,
                    String.class);
