在Android Web服务使用POST方法的REST模板，我试图发送一个对象到服务器，其中包含几个参数和2个对象。这两个对象包含几个参数和3个不同对象的列表，并且这3个对象列表中的每一个都包含其中的少量参数以及1个仅包含字节数组的对象列表。像在下面的图片：org.springframework.web.client.HttpClientErrorException：415不支持的媒体类型[编辑]
产品图1 [主要对象（一个我想发送）〕：
产品图2包括对象的3只列出了主要对象内对象]：
产品图3的为包含1个列表内它的另一个对象的，同样对其他2（住宿&其他）列表对象]：
产品图4仅含有一个牛栏数组参数子对象内的对象的列表]：
而我的用于web服务POST方法的代码：
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;
}
无论我做什么回报org.springframework.web.client.HttpClientErrorException: 415 Unsupported Media Type
我LOGCAT如下：

我实际上是想发送对象的数据为每个列表服务器的照片以及目录列表。 浏览了几个网站和几乎所有与Stack Overflow上的错误有关的主题，在这个问题上已经持续了一个多星期。希望我能找到一些帮助。
我们必须看到您的端点所期望的。 – user2447161
我收到一个错误，指出'org.springframework.web.client.HttpClientErrorException：415 Unsupported Media Type'。我甚至没有在服务器端得到任何日志 – sam
