java - 从 JBloomberg API 检索实时数据

Question

我想以双倍形式检索时间和实时最后价格，而不是像这样的输出

DataChangeEvent{ESA Index,ASK_SIZE: 204==>192}

来自下面的代码

DataChangeListener lst = new DataChangeListener() {
 @Override
 public void dataChanged(DataChangeEvent e) {
     System.out.println(e);
 }
};


SubscriptionBuilder builder = new SubscriptionBuilder()
     .addSecurity("ESA Index")
     .addField(RealtimeField.LAST_PRICE)
     .addField(RealtimeField.ASK)
     .addField(RealtimeField.ASK_SIZE)
     .addListener(lst);
session.subscribe(builder);


Thread.sleep(3000);

刚刚看到你的问题，所以可能有点晚了 - 但无论如何，它就在这里。 DataChangeEvent包含股票行情、字段、新旧价格:

DataChangeListener lst = new DataChangeListener() {
     @Override public void dataChanged(DataChangeEvent e) {
         String ticker = e.getSource();
         String field = e.getDataName();
         double oldValue = e.getOldValue().asDouble();
         double newValue = e.getNewValue().asDouble();
     }
};
