Post url seems not been called with spring security - spring

Question

My issue is that, when I call the url http://localhost:8080/site/data/gouv/ with postman with corresponding form data parameters, nothing happens. It seems even the call is not catched by the controller because there is no log.
Postman page
Here is the controller :
package com.mintad.spring.controllers;
import java.io.BufferedInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.ArrayList;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
import com.site.common.beans.Gouv;
import com.site.common.service.GouvService;
import au.com.bytecode.opencsv.CSVReader;
#RestController
#RequestMapping("/data")
public class DataController {
#Autowired
private GouvService gouvService;
#RequestMapping(value = "/gouvernorate", method = RequestMethod.POST)
public ResponseEntity<Gouv> addGouvernorate(#RequestBody Gouv gouv) throws IOException {
gouvService.addGouv(gouv);
return new ResponseEntity<Gouv>(gouv, HttpStatus.OK);
}
}
I've tried to call the url with Jsoup as follows :
String base64login = new String(Base64.encode("sof:1".getBytes()));
Document docs = Jsoup.connect("http://localhost:8080/site/data/gouv/").header("Authorization", "Basic " + base64login).
data("name", "name").
data("delegation", "delegation").
data("district", "district").
data("postalCode", "postalCode").post();
But in vain.
Any help please ? I'm using spring security 4.0.4.RELEASE and Spring 4.2.5.RELEASE
