来自Transformer的Spring Integration路由消息

Question

I have intergration setup as

    IntegrationFlows.from("ValidFile")
    .transform(
    Transformer(new FindTheDepartItbelongs()) //basically file has to match to some depoartment
    .transform(new FileParserTransformer()
.transform(new DataSplitterTransformer()
    .transformer(new CustomerTransformer()
    .handle (o -> {})

As you see the DataSplitterTransformer () basically I have to group the data for example Department ID.

Now lets say I get three records with department id (1 and 3)

I want to pause at DataSplitterTransformer() and route the message to "ValidFile" again

It will be two message 1 for department 1 and one for 3

Is that possible?

Answer 1

Your configuration is not clear with such an explanation. Sounds like you are missing the fact that there are .split() for producing several output from a single message and also a .route() to decide where to send every message according selector logic.

You can really route back to the ValidFile channel and also you can continue in the main flow using defaultOutputToParentFlow() .

See their Javadocs for more info.
