Spring integration flow Design -


this going second project going implement using spring integration. confident architecture after successful release o f first project .but have few clarification required define flow of external calls. in architecture have multiple call database,web service , cache server , have defined these flows in single flow .

scenario 1.

channel- >jdbcoutbound -> router ->splitter ->wsoutbound -> aggregator ->reply channel.

here external service call execute single gateway. these approach or can define separate gate way call below

scenario 2.

seq 1) gateway ->jdbcoutbound -> router ->reply channel.  seq 2) gateway(use response seq 1) ->splitter ->wsoutbound -> aggregator ->reply channel

which scenario best ?

it depends of requirements.

as noticed both variants work well. so, big height matter of taste. but... let's take @ useful or noise function in our project!

gateway designed distribute business , integration logic between separate layers. other side gateway approach spring's autowiring feature allows have high-level api our integration solution.

so, think bit further if there need expose such high-level api second call.

no reason divide our configuration finely if <channel> , <service-activator> (or similar) pair enough reach solution!

from other side it's opinion. you'll find own style experience.
