I working on liberty 18.0.0.2 with JavaEE 8 .
I created Custom jms object message like this :
public class MyTextMessage implements Serializable {
private String text;
private String destination;
private LocalDateTime dateTime;
public MyTextMessage(String text, String destination, LocalDateTime dateTime) {
this.text = text;
this.destination = destination;
this.dateTime = dateTime;
}
public MyTextMessage() {
}
// Getter and Setter
@Override
public String toString() {
return "MyTextMessage{" +
"text='" + text + '\'' +
", destination='" + destination + '\'' +
", dateTime=" + dateTime +
'}';
}
}
How can select on queue by object property ?
this is my code but not work :
JMSConsumer consumer = context.createConsumer(destination, "destination='abcdefg'");
Message message = consumer.receiveNoWait();
if (message != null) {
MyTextMessage myTextMessage = message.getBody(MyTextMessage.class);
System.out.println(myTextMessage);
}
You're trying to select on the property of an ObjectMessage implementation which is technically part of the body of the message. However, section 3.8.1 of the JMS 2 specification states:
Message selectors cannot reference message body values.
A message selector matches a message when the selector evaluates to true when the message’s header field and property values are substituted for their corresponding identifiers in the selector.
Therefore, you need to set a property on the message with a value you can select on (e.g. using javax.jms.Message.setStringProperty("destination", "abcdefg")).
