休息模板接受标题

Question

我尝试将Accept标头设置为 application / json ，在服务调用期间，我可以看到“ DEBUG osweb.client.RestTemplate - 将请求接受标头设置为[text / plain， / ]“用日志写的。我的接受标题被覆盖了吗？如何限制？

代码段：

    RestTemplate template = new RestTemplate();
HttpHeaders requestHeaders = new HttpHeaders();
        requestHeaders.add(HttpHeaders.CONTENT_TYPE, APPLICATION_JSON);
        requestHeaders.add(HttpHeaders.ACCEPT, APPLICATION_JSON);
String url = "http://*******"
HttpEntity<String> request = new HttpEntity<String>(requestBody, requestHeaders);
HttpEntity<String> response = template.exchange(url, HttpMethod.POST, request, String.class);

日志：

{Content-Type=[application/json], Accept=[application/json]}

13:08:06.091 [main] DEBUG o.s.web.client.RestTemplate - Created POST request for "http://********"
13:08:06.097 [main] DEBUG o.s.web.client.RestTemplate - Setting request Accept header to [text/plain, */*]
