View solution

Q. A splitter takes an input message and asks you, the user of the component, on what basis it should split the Message.

View solution

Q. Spring Integration ships with useful splitters that require no customization.

View solution

Q. Return type of the method annotated by the @Splitter annotation is of type:-

Q. Annotation which collects a series of messages (based on some correlation that you help Spring Integration make between the messages).

View solution

Q. To determine how many messages to read until it can stop:-

View solution

Q. For correlation when you might not have a size but know that you’re expecting messages that share a common header value within a known time, Spring Integration provides the HeaderAttributeCorrelationStrategy.

View solution

Q. The only custom logic is a POJO with an @Aggregator annotation on a method expecting a collection of Message objects.

View solution

Q. You want to conditionally move a message through different processes based on some criteria.

View solution
