Aggregate Example
Available as of Camel 2.3
About
This example demonstrates the new overhauled Aggregator EIP in Apache Camel 2.3. The example is focused on the persistence support, which means the aggregated messages is stored in a persistent file storage using the new HawtDB component.
How to run
You simply run it using the following maven goal: mvn camel:run
How it works
The example is an interactive example where it prompt on the console for you to enter a number and press ENTER. The numbers you enter will then be aggregated and persisted. That means you can at any time hit ctrl + c to shutdown Camel. Then you should be able to start the example again and resume where you left.
When you want to complete the aggregation you can enter STOP as input and Camel will show you the result, which is the sum of all the numbers entered.
The persistent datastore is located in the data/hawtdb.dat file. Its automatic created the first time.
Using Aggregator
The example is configured as follows in Spring XML.
TODO: e1
And it has a AggregationStrategy to sum the numbers which is done in Java code as:
