在Android Web服務使用POST方法的REST模板，我試圖發送一個對象到服務器，其中包含幾個參數和2個對象。這兩個對象包含幾個參數和3個不同對象的列表，並且這3個對象列表中的每一個都包含其中的少量參數以及1個僅包含字節數組的對象列表。像在下面的圖片：org.springframework.web.client.HttpClientErrorException：415不支持的媒體類型[編輯]
產品圖1 [主要對象（一個我想發送）〕：
產品圖2包括對象的3只列出了主要對象內對象]：
產品圖3的爲包含1個列表內它的另一個對象的，同樣對其他2（住宿&其他）列表對象]：
產品圖4僅含有一個牛欄數組參數子對象內的對象的列表]：
而我的用於web服務POST方法的代碼：
public static final String capUrl = "http://192.168.1.7:8084/CAPWS";
public Expenses setExpensesByBatch(Expenses expenses) {
try {
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
RestTemplate restTemplate = new RestTemplate();
restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter());
restTemplate.getMessageConverters().add(new StringHttpMessageConverter());
restTemplate.setRequestFactory(new HttpComponentsClientHttpRequestFactory());
List<HttpMessageConverter<?>> list = new ArrayList<HttpMessageConverter<?>>();
list.add(new MappingJacksonHttpMessageConverter());
restTemplate.setMessageConverters(list);
String b = restTemplate.postForObject(capUrl + "/UX/", expenses, String.class);
Log.e("String ===============b", b + " ++++");
} catch (Exception e) {
e.printStackTrace();
Log.e("expObjPost_WsCli_EX", e.toString());
}
return expenses;
}
無論我做什麼回報org.springframework.web.client.HttpClientErrorException: 415 Unsupported Media Type
我LOGCAT如下：
我的服務器端代碼：

我實際上是想發送對象的數據爲每個列表服務器的照片以及目錄列表。 瀏覽了幾個網站和幾乎所有與Stack Overflow上的錯誤有關的主題，在這個問題上已經持續了一個多星期。希望我能找到一些幫助。
我們必須看到您的端點所期望的。 – user2447161
我收到一個錯誤，指出'org.springframework.web.client.HttpClientErrorException：415 Unsupported Media Type'。我甚至沒有在服務器端得到任何日誌 – sam
