私のWebサービスを実装するためにJerseyを使用しています。 Jersey Client APIに基づいてこれらのサービスを使用するJavaクライアントを作成しています。文字列、地図、ビジネスオブジェクトのリストを返すWebサービスを呼び出すと、すべてOKになり、クライアント側で期待される応答が得られます。しかし、文字列やintを返すWebサービスを呼び出すと、JavaIOException：premature EOFが発生します。 この問題についてご意見はありますか？Jersey Client API - サービスを利用する際のJavaIOException早期EOFの取得
私はこのように私のクライアントをインスタンス化しています：
String serviceUrl = "http://localhost:9998";
ClientConfig config = new DefaultClientConfig();
config.getFeatures().put(JSONConfiguration.FEATURE_POJO_MAPPING, Boolean.TRUE);
Client client = Client.create(config);
resource = client.resource(serviceUrl + "/infos");
resource.accept(MediaType.APPLICATION_JSON_TYPE);
方法私は文字列を返す必要が呼んでいる：ここで
public String getInfo() {
return resource.get(String.class);
}
はエラースタックトレースです：
