huotoolを使う

        
            cn.hutool
            hutool-all
            4.5.16
        

cn.hutol.http.HttpRequestオブジェクトを使用してデフォルトでSSL認証をスキップします。

  public void test(){
    JSONObject requestJson = new JSONObject();
    requestJson.put("name", "zhang3");
    requestJson.put("age", 10);
    String requestParam = requestJson.toJSONString();
    HttpResponse responseObj = HttpRequest.post("https://www.baidu.com").body(requestParam).execute();
  }
