Hi all,
I have a question how to load (add or remove) route steps dynamically with
Java/Java DSL.
For example, I have a route with around 20 steps. The users can configure
which steps are used and which not.
Now the creating of the route has the following steps:
1) Write code (Java DSL)
2) Compile code
3) Load (Add) Route
4) Start Route
5) Run Route
I have the option to write multiple routes and load the route based on user
preferences. But this is not desirable because I need to maintain tens of
routes (instead of a few). The other possibility is that I add a choice
step and let it happen in runtime (but this takes unneeded performance, as
it already known on load if these steps are needed or not.
What are my options of add/remove steps on loading a route?
Things I came up with (but I am not sure if they are possible):
1) Change from Java to XML and manipulate the XML (Preferable not)
2) Add construction in route to load or not. For example:
split("mySplit").loadStep(true/false)
When false this step is removed on load.
3) Create the route as string and load it dynamically on start (something
like RouteLoader). Of course there are multiple instances running with
different configuration.
4) Use a RouteTemplate and somehow configure if a step is used or not based
on parameters.
5) Use some aspect programming, just like unit tests: weaveById(id).remove()
So I liked to avoid the first option (using XML), because and then need to
rewrite several routes. Is one of the other possible? Or is there another
possibility where I am unaware of?
