我试图在一个简单的Web应用程序中实现Hazelcast.
我正在尝试将自定义对象存储到我的Hazelcast地图中,并在我的出价对象类中实现了Serializable以及必要的导入.
import java.io.Serializable;
这是类对象的片段.
public class Bid implements Serializable{
private String bidId;
private String stock;
private int price;
private String userId;
private Date date;
以下是将Bid对象存储到Map中的语法,其中newBid是Bid对象.
Config cfg = new Config();
HazelcastInstance instance = Hazelcast.newHazelcastInstance(cfg);
Map<String, Bid> mapBids = instance.getMap("bids");
mapBids.put(newBid.getUserId(), newBid);
我的Hazelcast节点已启动并正在运行,但当我查询出价图时,出现以下错误.
