Jersey客户端抛出MessageBodyProviderNotFoundException

Question

我有一个抛出MessageBodyProviderNotFoundException的Jersey客户端在我的例子中，我可以使用moxy解析来自文件的JSON读取，然后我尝试使用Jersey客户端来解析相同的JSON

我检查了由moxy解析创建的WarehouseResponse实例，它看起来很完美。

示例代码

public class PlexExample {

    public static void main(String[] args) throws Exception {
        Class<?>[] ctx = {WarehousesResponse.class, WarehouseResponse.class, WarehouseFields.class};
        JAXBContext jc = JAXBContext.newInstance(ctx);
        Unmarshaller um = jc.createUnmarshaller();
        um.setProperty(UnmarshallerProperties.MEDIA_TYPE, "application/json");
        um.setProperty(UnmarshallerProperties.JSON_INCLUDE_ROOT, false);
        Source json = new StreamSource(new File("D:\\CM_First\\Pacorini\\Workspace\\Resources\\warehouses.json"));
        WarehousesResponse warehouses = um.unmarshal(json, WarehousesResponse.class).getValue();
        ObCharFld url = new ObCharFld("http://localhost:8080/HSyncREST007/api/v1");
        ObCharFld path = new ObCharFld("warehouses");
        warehouses = executeGET(url, path);
    }

    public static WarehousesResponse executeGET(ObCharFld obUri, ObCharFld obPath) {
        Client client = ClientBuilder.newClient();
        WebTarget target = client.target(obUri.getValue())
                .path(obPath.getValue());
        Invocation.Builder builder = target.request(MediaType.APPLICATION_JSON);
        Response response = builder.get();
        return  response.readEntity(WarehousesResponse.class); // Exception thrown here
    }
}

服务器将内容类型设置为text / x-json。我在获得响应后设置了响应头。

public static WarehousesResponse executeGET(ObCharFld obUri, ObCharFld obPath) {
    Client client = ClientBuilder.newClient();
    WebTarget target = client.target(obUri.getValue())
            .path(obPath.getValue());
    Invocation.Builder builder = target.request(MediaType.APPLICATION_JSON);
    Response response = builder.get();
    response.getHeaders().putSingle(HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_JSON);
    return  response.readEntity(WarehousesResponse.class); 
}
