使用Apache http client发送json数据（demo）

POM依赖 ：

        <dependency><groupId>org.apache.httpcomponents</groupId><artifactId>httpclient</artifactId><version>4.5.12</version></dependency><dependency><groupId>com.alibaba</groupId><artifactId>fastjson</artifactId><version>1.2.46</version></dependency>

客户端代码：

package xyz.jangle.httpclient.test;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;
//import org.json.JSONObject;import com.alibaba.fastjson.JSONObject;public class HttpClientSendJson {public static void main(String[] args) {try {// 创建HttpClient实例CloseableHttpClient httpClient = HttpClients.createDefault();// 创建HttpPost实例HttpPost httpPost = new HttpPost("http://127.0.0.1:8080/hello/test3");// 创建JSON数据JSONObject json = new JSONObject();
//            json.put("key1", "value1");
//            json.put("key2", "value2");json.put("shebeiId", "123");json.put("xiaoxiId", "456");json.put("xiaoxiType", "1");// 将JSON数据设置到StringEntity中StringEntity entity = new StringEntity(json.toString());// 设置内容类型entity.setContentType("application/json");// 设置HttpPost实例的实体httpPost.setEntity(entity);// 发送请求CloseableHttpResponse response = httpClient.execute(httpPost);// 获取响应内容String result = EntityUtils.toString(response.getEntity());// 输出结果System.out.println(result);// 关闭responseresponse.close();} catch (Exception e) {e.printStackTrace();}}
}

服务端接收方式：

    @RequestMapping(value = "/test3", method = RequestMethod.POST)@ResponseBodypublic Map<String, Object> test3(@RequestBody String test){Map<String,Object> map = new HashMap<String,Object>();//stringlogger.info("test:"+test);try {JSONObject jsonObject = JSONObject.parseObject(test);String shebeiId = jsonObject.getString("shebeiId");String xiaoxiId = jsonObject.getString("xiaoxiId");String xiaoxiType = jsonObject.getString("xiaoxiType");return xxx(shebeiId, xiaoxiId, map);} catch (Exception e) {map.put("code", 102);map.put("msg", e.toString());logger.error("异常：", e);return map;}}
