我正在尝试将curl请求转换为Spring的Resttemplate post请求，但是却收到403-错误的请求
我的卷曲请求
curl -d "grant_type=client_credentials&client_id=nu5yzeth9tektzf5egxuntp7&client_secret=uP2Xvr6SCKYgXgxxJsv2QkUG"
-H "Content-Type: application/x-www-form-urlencoded"
-X POST https://cloudsso.example.com/as/token.oauth2
卷曲响应：
{"access_token":"HVURQ845OPJqs8UpOlef5m2ZCNwR","token_type":"Bearer","expires_in":3599}
现在，这是我在上述curl post请求中实现的Java代码
RestTemplate restTemplate = new RestTemplate();
HttpHeaders headers = new HttpHeaders();
headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
MultiValueMap<String, String> bodyParamMap = new LinkedMultiValueMap<String, String>();
bodyParamMap.add("grant_type", "client_credentials");
bodyParamMap.add("client_id", "nu5yzeth9tektzf5egxuntp7");
bodyParamMap.add("client_secret", "uP2Xvr6SCKYgXgxxJsv2QkUG");
entity = new HttpEntity<>(reqBodyData, bodyParamMap);
restTemplate.postForEntity(url, entity, TokenDTO.class)
Resttemplate呼叫响应：

如何使restTemplate中的上述curl请求正常工作？
注意：https://cloudsso.example.com/as/token.oauth2对于该问题几乎没有修改。
