服务器的接口如果是springmvc客户端除了用springmvc提供的RestTemplate请求如下

public class RestClient {

    private static Logger logger = Logger.getLogger(RestClient.class);

    @SuppressWarnings({ rawtypes, unchecked })

    public static Object post(String url, Map<string, object=""> message) {

        Object result = null;

        try {

            RestTemplate rest = new RestTemplate();

            MultiValueMap<string, object=""> param = new LinkedMultiValueMap();

            for(Entry<string, object=""> entry : message.entrySet()) {

                param.add(entry.getKey(), entry.getValue());

            }

            result = rest.postForObject(url, param, String.class);

        } catch (Exception e) {

            logger.error(发送消息发生异常+e);

        }

        return result;

    }

}

import java.io.UnsupportedEncodingException;

import org.springframework.util.LinkedMultiValueMap;

import org.springframework.util.MultiValueMap;

import org.springframework.web.client.RestTemplate;

import test.ThreeDES;

public class TestPost {

public static void main(String[] args) {

    //spring方式

    RestTemplate rest = new RestTemplate();//创建org.springframework.web.client.RestTemplate

        MultiValueMap<String,Object> param = new LinkedMultiValueMap<String,Object>();//创建参数Map  org.springframework.util.LinkedMultiValueMap

        //map设值

        param.add("id", "1");

        param.add("carbonOrderNo", "M201702161055");

        param.add("name", "王烟");

        param.add("userTypes", "OTHER");

        param.add("tel", "13020232323");

        param.add("certificateNo", "99021023456");

        param.add("money", "2");

        param.add("donationWays", "CASHPAY");

        String result = rest.postForObject("http://localhost:8080/trip/bD/send?", param, String.class);//postForObject   post方式

        System.out.println(result);

}

}

还可以用httpclient发送请求如下:

package com.ckdh.web.test;

import java.io.BufferedReader;

import java.io.InputStream;

import java.io.InputStreamReader;

import org.apache.http.HttpEntity;

import org.apache.http.HttpResponse;

import org.apache.http.client.HttpClient;

import org.apache.http.client.methods.HttpPost;

import org.apache.http.entity.StringEntity;

import org.apache.http.impl.client.DefaultHttpClient;

public class DownloadResourcesTest {

    public static void main(String[] args) {

        String url = http://localhost:8080/xxx-web/xxx.mvc?apikey=1;

        HttpClient client = new DefaultHttpClient();  

        HttpPost httpPost = new HttpPost(url); 

        InputStream is = null;

        InputStreamReader isr = null;

        BufferedReader br = null;

        try {

            httpPost.addHeader(city, 010);

            httpPost.addHeader(version, 2);

            HttpEntity entity = new StringEntity(<infos><info hash="a0fd9704eb1432892cbc19742811b63" spid="88"> +

                    </info><info hash="e7b8894b8bc4d4eac22dffd85f28a68" spid="p1"></info></infos>);

            httpPost.setEntity(entity);

            HttpResponse response = client.execute(httpPost);

            System.out.println(response.getStatusLine());

            is = response.getEntity().getContent();

            isr = new InputStreamReader(is, UTF-8);

            br = new BufferedReader(isr);

            StringBuffer buf = new StringBuffer();

            String line;

            while (null != (line = br.readLine())) {

                buf.append(line).append();

            }

            System.out.println(buf.toString());

        } catch (Exception e) {

            e.printStackTrace();

        }

    }

}

SpringMVC template和HttpClient post提交
