1.RequestDTO类

public class RequestDTO {

private MetainfoDTO metainfo;

private DataInfoDTO datainfo;

public RespSchemeDTO(){

}

public MetainfoDTO getMetainfo() {

return metainfo;

}

public void setMetainfo(MetainfoDTO metainfo) {

this.metainfo = metainfo;

}

public DataInfoDTO  getDatainfo() {

return datainfo;

}

public void setDatainfo(DataInfoDTO datainfo) {

this.datainfo = datainfo;

}

 

2、HttpClientUtil工具类

public class HttpClientUtil{

public String Static doPost(String url,String json){

DefaultHttpClient client = new DefaultHttpClient();

client.getParams().setIntParameter(CoreConnectionPNames.CONNECTION_TIMEOUT, 3000);

client.getParams().setIntParameter(CoreConnectionPNames.SO_TIMEOUT, 3000);

HttpPost post = new HttpPost(url);

post.addHeader("Content-Type","application/json;charset=utf-8");

try{

StringEntity s = new StringEntity(json,"UTF-8");

s.setContentType("application/json");

post.setEntity(s);

HttpResponse res = client.execute(post);

byte[] re;

String result = null;

if (res.getStatusLine().getStatusCode() == HttpStatus.SC_OK){

HttpEntity entity = res.getEntity();

InputStream input = entity.getContent();

if (entity.isStreaming()){

re = org.apache.http.util.EntityUtils.toByteArray(entity);

result = new String(re,"iso-8859-1");

}else{

result = org.apache.http.util.EntityUtils.toString(entity);

}

return result;

}else

return null;

}catch(Exception e){

e.printStackTrace();

return null;

}

}

public Static<T> T JSONToObj(String json,Class<T> clazz){

T t=null;

try{

ObjectMapper objectMapper = new ObjectMapper();

t=objectMapper.readValue(json, clazz);

}catch(Exception e){

e.printStackTrace();

}

return t;

}

}

 

3、发送http请求

public class SendHttp{

String url="http://ip:port/run/app?trancode=app.services.business.push";

RequestDTO requestDTO=new RequestDTO();

MetainfoDTO metainfoDTO=new MetainfoDTO();

metainfoDTO.setField1(“field1”);

....

DataInfoDTO dataInfoDTO=new DataInfoDTO();

dataInfoDTO.setField2("field2");

....

requestDTO.setDatainfo(schemedto);

requestDTO.setMetainfo(resplist);

ObjectMapper objectMapper = new ObjectMapper();

String encryptString="";//加密前的json

String json="";//加密后的json

String decryptString="";//加密的结果

String result="";//解密的结果

try{

encryptString=objectMapper.writeValueAsString(requestDTO);//Method that can be used to serialize any Java value as a String

json=DES.encryptDES(encryptString);//将json字符串加密

}catch(IOException e){

e.printStackTrace();

}

decryptString=HttpClientUtil.doPost(url,json);

result=DES.decryptDES(decryptString);//解密

Map maps = (Map) HttpClientUtil.JSONToObj(result, Map.class);

....

}

4、HttpClientUtil类

public class HttpClientUtil {

public String sendHttpPost(String url,String json){

RequestConfig config = RequestConfig.custom()

.setSocketTimeout(150000)

.setConnectTimeout(150000)

.setConnectionRequestTimeout(150000)

.build();

CloseableHttpClient httpClient = null;

String responseContent = null;

HttpPost httpPost=new HttpPost(url);//创建HttpPost

httpPost.addHeader("Content-type","application/json;charset=utf-8");

httpPost.setHeader("Accept","application/json");

try{

StringEntity stringEntity = new StringEntity(json, "UTF-8");

stringEntity.setContentType("application/x-www-form-urlencoded");

httpPost.setEntity(stringEntity);

httpPost.setConfig(config);

CloseableHttpResponse response=httpClient.execute(httpPost);

HttpEntity entity=response.getEntity();

String responseContent=EntityUtils.toString(entity,"UTF-8");

}catch(Exception e){

e.printStackTrace();

}

return responseContent;

}

}
