httpclientローカルインタフェースをテストする

1.postリクエストインタフェースの送信

/**
     *  Post 
     * 
     * @param httpPost
     * @return
     */
    private static String sendHttpPost(HttpPost httpPost) {
        CloseableHttpClient httpClient = null;
        CloseableHttpResponse response = null;
        HttpEntity entity = null;
        String responseContent = null;
        try {
            //  httpClient .
            httpClient = HttpClients.custom()
                    .setSSLSocketFactory(SSLConnectionSocketFactory.getSocketFactory())
                    .setDefaultRequestConfig(requestConfig).build();
            //  
            response = httpClient.execute(httpPost);
            entity = response.getEntity();
            responseContent = EntityUtils.toString(entity, "UTF-8");
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            try {
                //  , 
                if (response != null) {
                    response.close();
                }
                if (httpClient != null) {
                    httpClient.close();
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
        return responseContent;
    }

2.テストを行う

@Test
    public void postTest() throws IOException {

        String path = this.getClass().getResource("/").getPath();
        //findLawCaceList.json  
        File file = new File(path + "/com/webapp/api/test/findLawCaceList.json");

        String param = FileUtils.readFileToString(file, "UTF-8");
        String digest = Encrypt.getSHA256(param);
        HttpPost post = new HttpPost("http://localhost: ");
        post.setEntity(new StringEntity(param, "UTF-8"));
        post.setHeader("digest", digest);
        String result = sendHttpPost(post);
        System.out.println(result);
    }
