java - Hazelcasl Rest API 二进制对象

Question

我正在使用 Hazelcast 的 Rest API 客户端。 MAP中存储的对象是BINARY格式的。

如何从 Rest 客户端查看这些对象？

Answer 1

我使用AsyncHTTPClient图书馆作为休息客户端。我假设您使用标准 Java 序列化，并且类 Person 实现了可序列化。

将对象存储在 Hazelcast 中

public class MyHazelcastClient {
    public static void main(String[] args) {
        HazelcastInstance hzClient = HazelcastClient.newHazelcastClient();
        Person person = new Person("Vik");
        final IMap<Object, Object> hzClientMap = hzClient.getMap("default");
        hzClientMap.set("key1", person);
        hzClient.shutdown();
    }
}

使用 REST api 从 Hazelcast 读取对象

    public class RestClient {
        public static void main(String[] args)
            throws ExecutionException, InterruptedException, IOException, ClassNotFoundException {
            AsyncHttpClient asyncHttpClient = new AsyncHttpClient();
            Response r = asyncHttpClient.prepareGet("http://127.0.0.1:5701/hazelcast/rest/maps/default/key1")
                    .execute().get();
            ObjectInputStream objectInputStream = new ObjectInputStream(
                new ByteArrayInputStream(r.getResponseBodyAsBytes()));
            final Person o = (Person) objectInputStream.readObject();
            System.out.println(o.toString());
        }
    }

希望对您有帮助!

干杯，
