35 35  The best practice for setting up your asynchronous routing process is to use one SpEL expression that determines to which offramp queues a messages needs to be routed.
36 36  The SpEL expression looks as follows:

67 -As the asynchronous routing plays a role in routing messages between all asynchronous flows in the messaging solution you can imagine that making changes does not need to happen lightly. The other aspect is that when multiple projects are being built at the same time the asynchronous routing will house a multitude of changes that need to go to Acceptance or Production at the same time.

69 69  One control mechanism we consider a best practice to guard yourself against those risks is to add a filter before data is placed on the offramp queue.
70 70  By doing this consistently you can control when a specific offramp can receive data on any environment. In other words, when a certain system is not ready yet to receive data on Acceptance or Production but is ready on Test you can control this behavior with this solution.

107 +Build your asynchronous routing based on the best practice for one of the offramps that are available within your (Academy) project.
108 +This assignment can be completed with the help of your (Academy) project you have created/used in the previous assignment.

111 111  * Use one component that decides to route messages to certain channels
112 112  * Control the output with a filter to prevent data to be sent to a queue too early
113 113  * Use the annotations to write down the step by step guide within your asynchronous routing
