HttpClient的PostMethod请求请求体传递参数

工作中遇到使用Postmethod请求，参数以body形式进行传递，记录下，以免以后忘记，话不多说，直接上代码

PostMethod postMethod = new PostMethod("url");

            RequestEntity se = new StringRequestEntity(JSONObject.toJSON(esFinanceParamDTO).toString(), "application/json", "UTF-8");
            postMethod.setRequestEntity(se);
            httpclient.executeMethod(postMethod);
            String respstr = postMethod.getResponseBodyAsString();
            System.out.println(respstr);
       

备注：esFinanceparamDTO是请求需要传递的参数对象，转成json进行传递
