使用SSM架构创建了一个solr服务层，通过HttpClient doPost()请求带string字符串参数访问服务，发现拦截器接收到的String乱码，问题出在String字符串是json格式！！！

- 解决方法

“

 java
 // 封装Httpclient请求
public static String doPostJson(String url, String json) {
        // 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);
            // 创建请求内容
            StringEntity entity = new StringEntity(json, ContentType.APPLICATION_JSON);
            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;
    }

 //调用search服务
    private TaotaoResult importItem(TbItem tbItem) throws UnsupportedEncodingException {
        try {
            String tbitem = JsonUtils.objectToJson(tbItem);
            HttpClientUtil.doPostJson(SEARCH_ITEM_SYNC_URL,tbitem);
        }catch (Exception e){
            return  new Result(500);
        }
        return  new Result(200);
    }

//拦截请求url
    @RequestMapping(value = "/manager/updateindex",method = RequestMethod.POST)
    @ResponseBody
    public TaotaoResult updateIndex(HttpServletRequest request) throws Exception {
        // 读取请求内容
        BufferedReader br = new BufferedReader(new InputStreamReader(request.getInputStream()));
        String line = null;
        StringBuilder sb = new StringBuilder();
        while((line = br.readLine())!=null){
            sb.append(line);
        }
        // 将资料解码
        String reqBody = sb.toString();
        String content = new String(reqBody.getBytes("UTF-8"));

        Result Result = itemService.updateItemIndex(content);
        return Result;
    }
