Apache HttpClient +4将数据发布到静态服务

Question

我需要使用apache HttpClient +4将数据发布到我的api，静态服务中，但是我无法正常工作，我已经尝试过：

    String url = "http://localhost:6768/rest/cmp/prods";
    List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
    nameValuePairs.add(new BasicNameValuePair("key", "value"));
    EntityBuilder entityBuilder = EntityBuilder.create().setParameters(nameValuePairs);
    HttpPost post = new HttpPost(url);
    post.setEntity(entityBuilder.build());
    CloseableHttpClient httpClient = HttpClients.custom().build();
    CloseableHttpResponse response = httpClient.execute(post);

返回

  

HTTP / 1.1 400错误请求

如何使用apache httpclient将数据发布到我的Restful服务？
