我解释一下我的问题。我发送一个来 self 的 User 类的对象。我将其从我的网站发送到我的 Restful 服务。但我尝试拥有它，并且我在参数中尝试的所有类型都无效或为 null :

发送类(class): 

   public String update() {
    try {
        if(mdpVerification.equals(utilisateur.getMotDePasse())){
        clientRest.setPath("user");
        clientRest.putEntity(SessionBeanEFPlanning.getAdministrateur().getLogin()
                , SessionBeanEFPlanning.getAdministrateur().getMotDePasse(), utilisateur, utilisateur.getId());
        SessionBeanEFPlanning.displayFacesMessage(FacesMessage.SEVERITY_INFO, "L'utilisateur a été modifié avec succès!");
        setUtilisateur(null);
        setUtilisateurs(null);
        super.getUtilisateurs();
        return "/utilisateurs/index?faces-redirect=true";
        }else{
        SessionBeanEFPlanning.displayFacesMessage(FacesMessage.SEVERITY_INFO, "Les mot de passes ne concordent pas !");    
        return "/utilisateur/edit?faces-redirect=true";
        }
    } catch (serverIllegalStateException exception) {
        String message = "";
        if (exception.getMessage().toLowerCase().contains("erreur : pseudo identique")) {
            message = "Ce pseudo est déjà attribué !";
        } else if (exception.getMessage().toLowerCase().contains("erreur : email identique")) {
            message = "Cet email est déjà attribué !";
        } else {
            message = exception.toString();
        }
        SessionBeanEFPlanning.displayFacesMessage(FacesMessage.SEVERITY_ERROR, message);
        return "/utilisateurs/edit?faces-redirect=true";
    }
}

我已经查看过我的对象是否为空，但事实并非如此!我给你讲授如何发送信息:

public Object putEntity(String login, String password, Utilisateur JsonObject,  Long id) {
    WebTarget webTarget = client.target(URI_REST_SERVICE)
            .path(URI_PATH)
            .path(Long.toString(id))
            .queryParam("login", login)
            .queryParam("password", password);
    System.out.println(webTarget);
    return super.<Utilisateur>putEntity(webTarget, JsonObject, new GenericType<Utilisateur>() {
    });
}

及其界面:

protected <T> T putEntity(WebTarget webTarget, T entity, GenericType genericType) {
    Response response = put(webTarget, entity);
    checkStatus200(response);
    return (T) response.readEntity(genericType);
}

现在我给你接收类:

@PUT
@Path("/{id : \\d+}")
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public Response updateUser(@QueryParam("login") String login,
        @QueryParam("password") String password,@PathParam("id") long id, JsonArray  utilisateur) {
    try {
        System.out.println(utilisateur);
        if (utilisateur != null) {
           // mapper.update(utilisateur);
            return Response.status(Response.Status.OK).entity(utilisateur).build();
        } else {
            return Response.status(Response.Status.NOT_FOUND).entity(
                    new MessageServiceErreur("Erreur utilisateur NULL")).build();
        }
    } catch (IllegalStateMessage exception) {
        return Response.status(Response.Status.INTERNAL_SERVER_ERROR).entity(
                new MessageServiceErreur(exception.toString())).build();
    } 

}

就像标题所说，我的 tomcat 日志中出现此错误::

我的问题是:如何才能正确接收信息？

最佳答案

错误消息告诉您它无法将收入 JSON 反序列化为 JsonArray。

"How can I receive the information correctly ?"

  1. 使用 POJO 而不是 JsonArray 作为方法参数。
  2. 确保您有 Json Provider

注意:上一个链接用于 JSON/POJO 支持。如果您想继续使用 Javax.json 类(即 JsonArray)，您也可以只包含以下依赖项(支持 JSON-P)

<dependency>
    <groupId>org.glassfish.jersey.media</groupId>
    <artifactId>jersey-media-json-processing</artifactId>
    <version>${jersey2.version}</version>
</dependency>

这一切都在 Jersey docs: Support for Common Media Type Representations 中有解释。
