Error Handling In Spring Integration

Integration. You will see that error handling is different between synchronous and asynchronous messaging. As usual, I'll skip the spring integration error handler chat and proceed with some examples. You can get the source
Spring Integration Chain Error Handling
code at github. 2 The sample application I will use a basic example, since I want to spring integration error channel example focus on exception handling. The application consists in an order service, which receives an order, processes it and returns a confirmation. Below we can see how the messaging system spring integration error handling service activator is configured: int-config.xml The gateway is the entry point of the messaging system. It will receive the order and send it to the direct channel "requestChannel" where a router will redirect it to the appropriate channel based on the order id: syncChannel: A direct channel that will send the order to an order processor subscribed to this channel.
Spring Integration Exception Handling Example
asyncChannel: A queue channel from which the order processor will actively retrieve the order. Once the order is processed, an order confirmation will be sent back to the gateway. Here is a graphic representing this: Ok, let's start with the simplest case, synchronous sending using a Direct Channel. 3 Synchronous sending with Direct channel The order processor is subscribed to the "syncChannel" Direct Channel. The "processOrder" method will be invoked in the sender's thread. Now, we will implement a test that will provoke an exception by sending an invalid order. This test will send an order to the gateway: The test: TestSyncErrorHandling.java We run the test and see how an exception is raised in the order processor and reaches the test. That's fine; we wanted to validate that sending an invalid order raised an exception. This happened because the test sent the order and blocked waiting for the order to be processed in the same thread. But, what happens when we use an asynchronous channel?

Below is the Use case and it will be synchronous channel. So in the chain there will be a set of service activator to perform the business logic. Now if there is any exception in the service error handling in activator present in the chain, I want that to be handled in the chain itself and continue with the other splitted messages. Inorder to do that, I have tried adding header enricher for error handler in the chain.But did not work. Any suggestion. Object1 contains List < Object2 > Flow: List < Object1 > --> Splitter1 (for Object1) --> Splitter2 (for Object2) --> Chain --> Aggregator --> Aggregator Code
