httpclient 的 doPost请求中文乱码问题

httpclient 的 doPost请求中文乱码问题
解决方案：

@RequestMapping(value="receiveTopic",method = RequestMethod.POST,  produces =MediaType.TEXT_PLAIN_VALUE+";charset=utf-8")

String url ="http://localhost/*****/receiveTopic.do";

String str = HttpClientUtil.doPost(url, param);

public static String doPost(String url, Map<String, String> param) {
        // 创建Httpclient对象
        CloseableHttpClient httpClient = HttpClients.createDefault();
        CloseableHttpResponse response = null;
        String resultString = "";
        try {
            // 创建Http Post请求
            HttpPost httpPost = new HttpPost(url);
            // 创建参数列表
            if (param != null) {
                List paramList = new ArrayList<>();
                for (String key : param.keySet()) {
                    paramList.add(new BasicNameValuePair(key, param.get(key)));
                }
                // 模拟表单
                UrlEncodedFormEntity entity = new UrlEncodedFormEntity(paramList,"utf-8");
                httpPost.setEntity(entity);
            }
            // 执行http请求
            response = httpClient.execute(httpPost);
            resultString = EntityUtils.toString(response.getEntity(), "utf-8");
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            try {
                response.close();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }

        return resultString;
    }

重点：

method = RequestMethod.POST,  produces =MediaType.TEXT_PLAIN_VALUE+";charset=utf-8"

UrlEncodedFormEntity entity = new UrlEncodedFormEntity(paramList,"utf-8");

即可解决中文乱码问题
