The FunctionInspector needs to be able to distinguish between a
function of Flux<Foo> and a function of Flux<Message<Foo>>. Then
it can do the conversion a level below.
Only supports Message->Message or POJO->POJO (no mixtures), so there
is only one new method in FunctionInspector.
No support in the web endpoints yet. But it's probably not so hard
to add.
If there is only one function you shouldn't have to set any configuration
to get a stream app to run. This also implementation supports multiple
functions, trying to guess which one to use based on the type of
the incoming message payload. In principle that could be strategized
as a simple router function (e.g. to look for a header with a function
name).
If there are functions and consumers in the same app, they will
subscribe to the same input channel (and hence by default Spring
Integration will load balance between them). This could also probably
use some more features, to specify the desired behaviour.
If user *does* supply spring.cloud.function.stream.endpoint then it
is used and overrides all other possible routes.
- use ProxyWrapper around a FluxConsumer as well
making it consistent with the behaviour of Flux
functions
- Enable introspection for scanned beans
- Fix failing tests by passing JSON string as input messages
(marshalled form expected from the binder)
Polished POM files to remove redundant entries that were causing warnings in the IDE. Some notable changes are:
- Removed spring-boot.version from sample project as they inherit it from the parent
- Removed versioning for maven-jar-plugin (was 3.0) from multiple project so it relies on the managed version
- Removed java.version from all spring-cloud-function-* modules as they inherit the one from parent.
Addressed PR comments
- removed references to maven-jar-plugin
Should be easy enoug hto add back later, but it was causing issues
with type conversion where we are npot yet sophisticated enough
to chain functions together and keep track of the types being
passed between them.
User can POST to web endpoint in SSE style, i.e:
HTTP/1.1
Content-Type: text/event-stream
data:foo
data:bar
Will be converted to a Flux with values foo and bar
Make it deployable via its maven coordinates in
spring-cloud-function-deployer (it is deployed by default on start
up right now, but that's just a demo)
