ResourceAccessException：POST请求时发生I/O错误

Question

尝试将数据发布到api时出错。下面是代码片段。期待早日得到帮助！谢谢

String id= Comment.getId();
String authStr = "userName:password";
String base64Creds = Base64.getEncoder().encodeToString(authStr.getBytes());
// create headers
HttpHeaders headers = new HttpHeaders();
headers.add("Authorization", "Basic " + base64Creds);
headers.setContentType(MediaType.APPLICATION_JSON);
JSONObject commonJsonObject = new JSONObject();
commonJsonObject .put("body","password");
SimpleClientHttpRequestFactory clientHttpRequestFactory = new SimpleClientHttpRequestFactory();
// Connect timeout: time is in milliseconds
clientHttpRequestFactory.setConnectTimeout(3000);
// Read timeout: time is in milliseconds
clientHttpRequestFactory.setReadTimeout(3000);
HttpEntity<String> request = new HttpEntity<String>(commentJsonObject.toString(), headers);
RestTemplate restTemplate = new RestTemplate(clientHttpRequestFactory);
String newCommentString = restTemplate.postForObject(url, request, String.class);

也许选择SimpleClientHttpRequest estFactory不是最好的解决方案...请尝试使用另一个实现-HttpComponentsClientHttpRequest estFactory：

var requestFactory = new HttpComponentsClientHttpRequestFactory();
requestFactory.setConnectTimeout(20000);
requestFactory.setConnectionRequestTimeout(20000);
requestFactory.setReadTimeout(30000);

SimpleClientHttpRequestFactory

ClientHttpRequestFactory实现，使用标准JDK工具。

HttpComponents客户端HttpRequestFactory

ClientHttpRequest estFactory实现，它使用Apache HttpComponents HttpClient创建请求。
