Comment utiliser MockMvcResultMatchers.jsonPath

MvcResult result = this.mockMvc.perform(
                MockMvcRequestBuilders.get(mockUrl))
                .andExpect(MockMvcResultMatchers.status().isOk())
            .andExpect(MockMvcResultMatchers.content().contentType("application/    json;charset=UTF-8"))
                .andDo(MockMvcResultHandlers.print())

Donnez moi ce qui suit:

MockHttpServletResponse:
           Status = 200
    Error message = null
          Headers = {Content-Type=[application/json;charset=UTF-8]}
     Content type = application/json;charset=UTF-8
             Body = {"version":"0.1"}
    Forwarded URL = null
   Redirected URL = null
          Cookies = []

Cependant, le tester avec 

MvcResult result = this.mockMvc.perform(
                MockMvcRequestBuilders.get(mockUrl))
                .andExpect(MockMvcResultMatchers.status().isOk())
            .andExpect(MockMvcResultMatchers.content().contentType("application/    json;charset=UTF-8"))
                .andExpect(jsonPath("$.version").value("0.1"))

renvoie l'erreur suivante:

Comment utiliser jsonPath?

Je pense que vous devez passer le Matcher à la méthode jsonPath. Par exemple.

.andExpect(jsonPath("$.version", is("0.1")))

Votre code fonctionne très bien pour moi. J'utilise Jackson pour analyser les cas et c'est probablement la seule différence. Vérifiez mon code:

Classe de résultat:

public class Res {
    String version;

    public String getVersion() {
        return version;
    }

    public void setVersion(String version) {
        this.version = version;
    }
}

Manette:

@RequestMapping(value = "/blah",
        method = GET,
        produces = APPLICATION_JSON_VALUE)
public HttpEntity<Res> doIt() {
    Res res = new Res();
    res.setVersion("0.1");
    return new HttpEntity<>(res);
}

Tester:

@Test
public void blahTest() throws Exception {
    this.mockMvc.perform(
            MockMvcRequestBuilders.get("/blah"))
            .andExpect(MockMvcResultMatchers.status().isOk())
            .andExpect(MockMvcResultMatchers.content().contentType("application/json;charset=UTF-8"))
            .andExpect(jsonPath("$.version").value("0.1"))
            .andDo(MockMvcResultHandlers.print());
}

Réponse:

MockHttpServletResponse:
           Status = 200
    Error message = null
          Headers = {Content-Type=[application/json;charset=UTF-8]}
     Content type = application/json;charset=UTF-8
             Body = {"version":"0.1"}
    Forwarded URL = null
   Redirected URL = null
          Cookies = []

Je ne peux que recommander d'essayer de changer la bibliothèque de l'analyseur Json que vous utilisez. Sinon, essayez de mettre à jour votre code avec toutes les pièces nécessaires pour créer un exemple simple, minimal et reproductible de votre problème.

Tout le mérite de cette réponse va à @pramodh (Caché dans les commentaires de OP)

J'ai eu exactement le même problème et l'installation de ses dépendances recommandées a tout corrigé.
