找不到媒体类型= application/octet-stream的MessageBodyReader

Question

我正在尝试使用以下代码片段从http://api.openweathermap.org/data/2.5/forecast/daily?lat=35&lon=139&cnt=10&mode=json接收json数据:

private WebTarget getWebTarget() {
    Client client = JerseyClientBuilder.newClient();
    return client.target("http://api.openweathermap.org/")
            .path("data")
            .path("2.5");
}

// new one method
    Response response = getWebTarget()
                        .path("daily")
                        .queryParam("q", String.format("%s,%s", town, countryCode))
                        .queryParam("cnt", 10)
                        .queryParam("mode", "json")
                        .request().accept(MediaType.APPLICATION_JSON_TYPE).get();
    WeatherForecast forecast = response.readEntity(WeatherForecast.class);

但最后一行抛出:

org.glassfish.jersey.message.internal.MessageBodyProviderNotFoundException:找不到媒体类型= application/octet-stream的MessageBodyReader,类型=类com.app.weather.providers.org.openweathermap.pojo.WeatherForecast,genericType = class com.app .weather.providers.org.openweathermap.pojo.WeatherForecast.

pom.xml中的Jersey依赖项:

            <!-- use the following artifactId if you don't need servlet 2.x compatibility -->

        </dependency>

此代码在应用程序服务器之外运行.谢谢.

通过编写自定义MessageBodyReader解决。https://jersey.java.net/documentation/latest/message-body-workers.html#d0e4072
