我们在做FIX开发的时候,经常遇到原生的FIX标签并不能满足我们的业务需求;这个时候就需要涉及到自定义的“字段”,“类”,“集合”。
message.setField(new DoubleField(6123), "value");
DoubleField field = message.getField(new DoubleField(6123));
上面的自定义方法在团队开发中,经常会引起不必要的麻烦(标签被重用,标签难以理解等问题。)
FIXJ官网推荐我们使用如下方法自定义Field
// RemiteNOField.java
import quickfix.StringField;
public class RemiteNOField extends StringField
{
public RemiteNOField () { super(C); }
public RemiteNOField (String data) { super(RemiteNOField , data);
}}
当然自定义完字段以后!需要在FIX4.4.xml文件中添加相应的Field描述。
<fields>
<field number="1" name="RemiteNOField" type="String" />
...
<field number="4" name="AdvSide" type="CHAR">
<value enum="B" description="BUY" />
<value enum="S" description="SELL" />
<value enum="X" description="CROSS" />
<value enum="T" description="TRADE" />
</field>
FIX中的Message相当我们理解的JAVA类。你可以自定义Message来描述一个对象。然后再XML文件中添加相应的Message描述。
注意:记得在35标签的位置添加相应的枚举
<value enum="Z6666" description="OrdersAfterSomeIDRequest"/>

public class OrdersAfterSomeIDRequest extends Message {

public static final String MSGTYPE = "Z6666";
public OrdersAfterSomeIDRequest() {

Group本质上是一个集合,其用来描述相同的属性的一类集合。qFixJ 充分的体现了其灵活性。
注意!在fields标签中添加相应的Field
/**
* @ClassName: FuturePositionsResponse
* @Description: 持仓信息
*
*/
public class FuturePositionsResponse extends Message {
private static final long serialVersionUID = 1L;
private static final String MSGTYPE = "Z3333";
public FuturePositionsResponse() {
getHeader().setField(new quickfix.field.MsgType(MSGTYPE));
}
public void set(Currency field) { // 货币类型
setField(field);

public void set(Symbol field) { // 标志
setField(field);
