How to aggregate all messages into a single message?

[arda.aydin]

Hi,

I want to use an aggregator in order to aggregate all messages comming.
On my route i'm making a split with a splitter , then i process every messages  in parallel
and then i want to aggregate them all into a single file.

Here is my snippet :


this.from(FROM_FOLDER).split(new LdapEntitySplitExpression()).process(new LdapModifyProcessor()).aggregate(header("LDIFRecord"),new LdapAggregationStrategy()).to(TO_FOLDER);


and inside  LdapModifyProcessor() i do:

exchange.getOut().setHeader("type", "LDIFRecord");

but it does not work.

can anyone tellme how can i let every messages go thru aggregator?

regards.

Hi

The splitter has build in join so you can do that all together with
the aggregator.

See the "Split aggregate request/reply sample" in
http://camel.apache.org/splitter.html

Try to use this.from(FROM_FOLDER).split(new LdapEntitySplitExpression(), new
LdapAggregationStrategy()).process(new
LdapModifyProcessor()).end().to(TO_FOLDER);

Thanks a lot dulanov, it worked :)


but can you tell me what exactly end() do and why i cant use the aggregator class ?

this.from(FROM_FOLDER)
.split(new LdapEntitySplitExpression(), new LdapAggregationStrategy())
.process(new LdapModifyProcessor())
.end()
.to(TO_FOLDER);

it works and aggregates processed messages into the same file but i want to complicate a little bit.

What i want to do is to split a file from a file endpoint, process each entry separately and then according to the entry content, i want to aggregate them into different files. So i wrote the code below but in this case the aggregation doesn't work, the outputs are in separate files.

this.from(m_from_folder_url)
        .split(new LdapEntitySplitExpression(),new LdapAggregationStrategy())
        .process(new LdapModifyProcessor(hMap))
                .choice()
                    .when(header("type").isEqualTo("add"))
                        .to(m_to_folder_url)
                    .when(header("type").isEqualTo("modify"))
                        .to(m_to_folder_url)
            .end();

So does anyone have an idea to solve it?

Thanks.

I resolved my problem by this way:

        this.from(m_from_folder_url)
        .split(new SplitExpression())
        .process(new Processor())
                .choice()
                    .when(header("type").isEqualTo("add"))
                        .to("direct:addEntry")
                    .when(header("type").isEqualTo("modify"))
                        .to("direct:modifyEntry");
       
        from("direct:addEntry").aggregate(header("add"), new AggregationStrategy()).to(m_to_add_folder_url);
        from("direct:modifyEntry").aggregate(header("modify"), new AggregationStrategy()).to(m_to_modify_folder_url);

so this is a route which:
 - reads a file
 - splits it's entities
 - processes each entry separately
 - according to their nature aggregating processed entries to the appropriate file.

but it does not work.

can anyone tellme how can i let every messages go thru aggregator?

Hi

Thanks for sharing your solution.
Looks nice with separate routes for the aggregation. Makes it easier
to test as well :)
