		***1.实现代码：***
		public void getPostMethod(String url){
		Map<String, Object> map = new HashMap<>();
		map.put("key1","value1");
		map.put("key2","value2");
		Map<String, Object> result = new HashMap<>();
		HttpClient httpClient = HttpClientBuilder.create().build();
		HttpPost httpPost = new HttpPost(url);
		httpPost.addHeader(HTTP.CONTENT_TYPE, "application/json;charset=utf-8");
		httpPost.addHeader("Content-type", "application/json; charset=utf-8");
		httpPost.setHeader("Accept", "application/json");
		httpPost.setEntity(new StringEntity(JSON.toJSONString(map), Charset.forName("UTF-8")));
		HttpResponse response = httpClient.execute(httpPost);
		if (null == response || response.getStatusLine() == null) {
			throw new Exception("Post Request For Url[{}] is not ok. Response is null");
		} else if (response.getStatusLine().getStatusCode() != HttpStatus.SC_OK) {
			throw new Exception("Post Request For Url[{}] is not ok. Response Status Code is {}");
		}
		String resultString = EntityUtils.toString(response.getEntity());
		JSONObject jsonObj = JSONObject.parseObject(resultString);
		if (jsonObj.getInteger("STATUS") == 6) {
			result.put("STATUS", "success");
			result.put("FILEID", jsonObj.getInteger("FILEID"));
		} else {
			result.put("STATUS", "failed");
		}
		result.put("MESSAGE", jsonObj.getString("MSG"));
		return result;
		}

2.POM.xml需要添加的依赖：

org.apache.httpcomponents
httpclient
4.4


org.apache.httpcomponents
httpmime
4.4
