Question

我创建了两个类：Initiator和Acceptor。我想从发起者向接受者发送消息，然后处理收到的消息。我无法发送消息。

这是我的initiator.java

SocketInitiator socketInitiator = null;
String fileName = "conf/intiator.cfg";
try {
    SessionSettings initiatorSettings = new SessionSettings(new FileInputStream(fileName));
    Application initiatorApplication = new Initiator();
    FileStoreFactory fileStoreFactory = new FileStoreFactory(
            initiatorSettings);
    FileLogFactory fileLogFactory = new FileLogFactory(
            initiatorSettings);
    MessageFactory messageFactory = new DefaultMessageFactory();
    socketInitiator = new SocketInitiator(initiatorApplication, fileStoreFactory, initiatorSettings, fileLogFactory, messageFactory);
    socketInitiator.start();
    Message msg = new Message();
    msg.setString(1, "Hello this is test Message");


    SessionID sessionId = (SessionID) socketInitiator.getSessions().get(0);
    Session.lookupSession(sessionId).logon();
    initiatorApplication.onLogon(sessionId);
    initiatorApplication.toApp(msg, sessionId);
} catch (Exception e) {
    e.printStackTrace();
}

以下是应用程序界面的overRide消息。

public void toApp(Message message, SessionID sessionId) throws DoNotSend {
    try {
        boolean result = quickfix.Session.sendToTarget(message, sessionId);
        if (result) {
            System.out.println("Message ahs send :)");
        } else {
            System.out.println("Not Send");
        }
    } catch (Exception e) {
        e.printStackTrace();
    }

}

这是发起人initiator.cfg文件

谁能告诉我问题出在哪里？在配置中还是在代码中？

Answer 1

我将指出显而易见的（此代码有很多错误，请参阅示例以了解quickfixj的工作原理）。您尝试发送的Message不是有效的FIX消息，因此在发送之前引擎会拒绝该消息。您需要创建一个真正的FIX消息，以便quickfix发送它。同样重要的是，我需要提一下toApp是一个在发送消息时被调用的事件处理程序。如果您打电话给quickfix.Session.sendToTarget，则会在发送时再次致电toApp。由于toApp中没有控制语句，因此会导致无限循环。配置也略有错误，其他代码看起来很奇怪，但这些是你最大的问题。请查看文档和示例。

Answer 2

您需要在xml文件中进行更改。我猜你正在使用的字段没有在fix.4.4文件中声明。检查您的xml文件并按以下方式包含它。

我希望发送带有货币的QuoteID，但是在货币中没有声明QuoteID。在这种情况下，您将无法发送消息。你需要在fix.4.4 /或你正在使用的任何版本中删除该字段（QuoteID）。

<Currency>
//
//   
<field name="QuoteID" required="N" /> // N or Y depend on your requirement 
//
//
</currency>

还检查日志，你会在那里找到错误信息。

可能是您不包括也会产生问题的必填字段。使用以下链接检查所需的字段。 http://www.fixprotocol.org/FIXimate3.0/
