Java 在同一个tomcat服务器中使用Apache Http客户端发送Json字符串

我正在尝试使用apache http客户端向服务器发送json。我已经尝试使用Gson和jackson API创建json字符串，我正在使用这两种方法获取有效的json字符串，但我面临的问题是使用apache http客户端发送json时，我收到了错误的请求。是json字符串被转换成类似于控制台上看到的无效json的问题还是其他问题。这是我的代码

objAuthRequest.setModality(objFITransXTRequest.getModality());
        objAuthRequest.setUidNumber(objFITransXTRequest.getUidNumber());
        objAuthRequest.setRrn("123456789133");
        objAuthRequest.setStan("12345600");
        objAuthRequest.setPid(objFITransXTRequest.getPid());
        objAuthRequest.setHmac(objFITransXTRequest.getHmac());
        objAuthRequest.setCi(objFITransXTRequest.getCi());
        objAuthRequest.setsKey(objFITransXTRequest.getsKey());
        objAuthRequest.setMetaData(objFITransXTRequest.getMetaData());

        try {

           Gson objGson = new Gson();
            String strRequestJson = objGson.toJson(objAuthRequest);
            System.out.println("Request json " + strRequestJson);

            response = objMWTHttpClient.execute(strRequestJson, URL);
            System.out.println("Response json " + response);
        } catch (Exception e) {
            logger.error("## Exception occured :: "+e.getMessage());
        }
        return response;

这是我的apache客户端代码

public String execute(String authenticateData, String srtULR) throws ParseException, Exception {
        String resoutput = "";
        try {
            HttpClient httpClient = HttpClientBuilder.create().build();
            //HttpPut reqFundTransf = new HttpPut(srtULR);
            HttpPost reqFundTransf = new HttpPost(srtULR);

            StringEntity params = new StringEntity(authenticateData);
            reqFundTransf.addHeader("content-type", "application/json");
            reqFundTransf.setEntity(params);
            HttpResponse resp = httpClient.execute(reqFundTransf);
            HttpEntity respEntity = resp.getEntity();
            if (respEntity != null) {
                resoutput = EntityUtils.toString(respEntity);
            }

        } catch (Exception e) {
            throw new Exception(e);
        }
        return resoutput;
} 

在控制台上，我收到这些消息

当我测试这个即将过时的json字符串时，它是无效的，这意味着语法不正确。我已经检查了java对象中的每个字段，一切看起来都很好。请指导怎么做。谢谢

编辑：我正在将请求从一个项目发送到同一服务器中的另一个项目。

错误请求是一个HTTP错误，它意味着您尝试了一个不正确的请求。你确定你必须使用POST吗？（可能是PUT？）或者也检查

内容类型

，确保它是

application/json

。是的，它是application/json，方法是post，但json的语法是正确的。您确定问题不在接收服务器端吗？你真的能通过第三方http客户端（cUrl，postman…）成功发布json吗？@Jeremy Grand，谢谢你提到postman。现在我从postman直接点击得到403状态“访问指定资源已被禁止”。我该怎么解决呢？嗯，您必须调查服务器为什么会限制对资源的访问。那是另一回事。没有你申请的任何信息，我无法神奇地解决你的问题。
