Httpclient 发送 post 请求封装json 格式参数

Httpclient 发送 post 请求可以封装多格式的参数，这篇我们封装json格式的：

1、客户端代码如下：

/**
     * 参数以json形式传送
     * @param request
     * @return
     * @throws IOException
     */
    public NmpResponse doPostJson(NmpRequest request) throws IOException {
        logger.info("------------开始POST请求-nmpHttpClient-----------");
        HttpClient httpClient = new HttpClient();
        httpClient.getHttpConnectionManager().getParams().setConnectionTimeout(15000);
        PostMethod postMethod = new PostMethod(NMP_ROOT_URL+request.getUrl());
        postMethod = setHeaderAuthInfo(postMethod);
        //添加请求参数
        String jsonParams = request.getJsonParam();
        System.out.println("推送参数："+jsonParams);
        postMethod.setRequestEntity(new StringRequestEntity(jsonParams,null,null));
        NmpResponse response = new NmpResponse();
        try {
            logger.info("------------开始执行POST请求，url:{}------------",NMP_ROOT_URL+request.getUrl());
            int statusCode = httpClient.executeMethod(postMethod);
            logger.info("------------POST请求结束，code={}------------",statusCode);
            if (statusCode == 200){
                response.setRespBody(postMethod.getResponseBody());
                response.setResponseStr(postMethod.getResponseBodyAsString());
                response.setRespHeaders(postMethod.getRequestHeaders());
            } else{
                logger.error("请求出错code={}：{}" ,statusCode ,postMethod.getStatusLine());
            }
        } catch (IOException e){
            logger.error("请求出错IOException：{}" ,e);
            throw e;
        } finally {
            postMethod.releaseConnection();
            logger.info("------------结束POST请求-nmpHttpClient-----------");
        }
        return response;
    }

2、服务端接收代码：

@RequestMapping(value = "/download/getListData")
    public Object queryPartitionList(@RequestBody PartitionVO partitionVO){
        if(Objects.isNull(partitionVO) ||StringUtils.isEmpty(partitionVO.getLayName()) ||CollectionUtils.isEmpty(partitionVO.getParNameList())){
            logger.error("Method:queryPartitionList 入参不能为空");
            return new JSONObject();
        }
        if (StringUtils.isEmpty(partitionVO.getProductVersion())){
            partitionVO.setProductVersion(Constant.ProductVersionLastest);
        }
       JSONObject jsonObject = new JSONObject();
       //业务代码省略
        return jsonObject;
    }
