aggregator - Spring-Integration AggregatingMessageHandler.setGroupTimeoutExpression visibility -

My business logic should be able to change the configured group timeout on the aggregator.

The code looks like this:

  @Autowired AggregatingMessageHandler messagesAgazilator; Public Zero Settime (integer timeout value) {Expression timeout expression = new spell expense parser (). ParseExpression (timeoutValue.toString ()); MessageAggregator.setGroupTimeoutExpression (timeoutExpression); }  

The problem is:

• I want to present the current value to the user, but ...
• Possible solution scenarios :
  • Should I put an expression on this vein and change its value,
    • Which means, the next time a message group is created, Can re-evaluate the expression with the result?
    • Should I expand the aggregating message handle with my own handler in which there is a public setter?
    • Or is it a bug and should it be fixed on the next release?

Not sure why you call it a bug, but your requirement Not standard.

Try to come together with some solution!

Since you want to convert group-timeout to runtime and you actually have a expression , your value is just integer You can use org.springframework.integration.expression.ValueExpression as the value atomic reference Code> Bean.

In this case, you just the existing value to the user :

  @Unible Private Atomic References & lt; Value Expression & gt; GroupTimeoutExpression; .... this.groupTimeoutExpression.get (). GetValue ();  

For the existing value, use that code for a new value expansion and AggregatingMessageHandler .

At the application startup, you should do this for the initial group-timeout . Or lift; Aggregator & gt; Copy / paste in value in the group-timeout attribute for and AtomicReference Bean.
