Comment puis-je faire le test http post junit avec contrôleur de démarrage de printemps

Question

Je voudrais poser des questions sur la façon dont je peux faire la demande de poste http avec contrôleur de démarrage à ressort. Mon corps http est un json, puis j'essaie de faire une requête http dans la fonction de test de junit.

package test.controller; 

import test.dto.RequestInput; 
import com.fasterxml.jackson.databind.ObjectMapper; 
import com.fasterxml.jackson.databind.module.SimpleModule; 
import com.google.gson.Gson; 
import com.google.gson.GsonBuilder; 
import groovy.json.JsonBuilder; 
import org.json.JSONObject; 
import org.junit.FixMethodOrder; 
import org.junit.Test; 
import org.junit.runner.RunWith; 
import org.junit.runners.MethodSorters; 
import org.springframework.beans.factory.annotation.Autowired; 
import org.springframework.boot.test.autoconfigure.web.servlet.WebMvcTest; 
import org.springframework.boot.test.context.SpringBootTest; 
import org.springframework.boot.test.web.client.TestRestTemplate; 
import org.springframework.http.HttpEntity; 
import org.springframework.http.HttpHeaders; 
import org.springframework.http.MediaType; 
import org.springframework.http.ResponseEntity; 
import org.springframework.mock.web.MockHttpServletRequest; 
import org.springframework.test.context.junit4.SpringRunner; 
import org.springframework.test.web.servlet.MockMvc; 
import org.springframework.test.web.servlet.MvcResult; 
import org.springframework.test.web.servlet.RequestBuilder; 
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders; 
import org.springframework.util.LinkedMultiValueMap; 
import org.springframework.util.MultiValueMap; 
import org.springframework.web.client.RestTemplate; 

import javax.servlet.http.HttpServletRequest; 
import java.io.BufferedReader; 
import java.io.FileReader; 
import java.io.IOException; 

@RunWith(SpringRunner.class) 
@FixMethodOrder(MethodSorters.NAME_ASCENDING) 
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT) 
//@WebMvcTest(value = RequestInput.class, secure = false) 
public class TestControllerTest { 
    @Autowired 
    private TestRestTemplate testRestTemplate; 

    @Test 
    public void testNewRequest() throws Exception { 
     String request = "{\"Uuid\": \"try_test_1\"}"; 

     ResponseEntity responseEntity = this.testRestTemplate.postForEntity("/test/request", new JsonBuilder(request).toPrettyString(), ResponseEntity.class); 
     System.out.println(responseEntity); 
    } 

} 

Cependant, j'ai essayé de faire la chaîne d'entrée qui devient un JSON,

public String inputJsonStringGetUuid (String inputJson) throws Exception{ 
     String Uuid; 
     ObjectMapper mapper = new ObjectMapper(); 
     RequestInput request; 
     try { 
      request = mapper.readValue(inputJson, RequestInput.class); 
     } catch (Exception e) { 
      throw new Exception("stringToRequestInput() - Format Error - Process STOP."); 
     } 
     Uuid = request.getUuid(); 
     return Uuid; 
    } 

et je l'ai trouvé fonctionne pas et le flux ci-dessous erreur:

S'il vous plaît aider, merci . :)

Answer 1

Parce que vous n'utilisez pas le type de réponse approprié, vous pouvez simplement utiliser String ou d'autres types appropriés. Par exemple:

ResponseEntity<String> responseEntity = this.testRestTemplate.postForEntity("/test/request", request, String.class);
