1. RequestDTO class
public class RequestDTO {
private MetainfoDTO metainfo;
private DataInfoDTO datainfo;
public RespSchemeDTO(){
}
public MetainfoDTO getMetainfo() {
return metainfo;

public void setDatainfo(DataInfoDTO datainfo) {
this.datainfo = datainfo;
}
2. HttpClientUtil tool class
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);

return null;
}catch(Exception e){

}
}
3. Send http request
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="";//json before encryption
String json="";//encrypted json
String decryptString="";//encryption result
String result="";/ / Decrypted result
try{
encryptString=objectMapper.writeValueAsString(requestDTO);//Method that can be used to serialize any Java value as a String
json=DES.encryptDES(encryptString);//Encrypt json string
}catch(IOException e){
e.printStackTrace();
}
decryptString=HttpClientUtil.doPost(url,json);
result=DES.decryptDES(decryptString);//Decrypt
Map maps = (Map) HttpClientUtil.JSONToObj(result, Map.class);
....
}
