Splitters

To create a splitter, use the split() EIP method. By default, if the payload is an Iterable, an Iterator, an Array, a Stream, or a reactive Publisher, the split() method outputs each item as an individual message. It accepts a lambda, a SpEL expression, or any AbstractMessageSplitter implementation. Alternatively, you can use it without parameters to provide the DefaultMessageSplitter. The following example shows how to use the splitWith() method by providing a lambda:

@Bean
public IntegrationFlow splitFlow() {
    return IntegrationFlow.from("splitInput")
              .splitWith(s -> s.applySequence(false).delimiters(","))
              .channel(MessageChannels.executor(taskExecutor()))
              .get();
}

The preceding example creates a splitter that splits a message containing a comma-delimited String.
