The web module doesn't really need to depend on tomcat and all of
the Spring Boot web stack, but users need a way to grab that stuff
quickly if they want it (hence the new starter).
Also removed all spring-boot-starter dependencies from core and
context modules.
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.
The compiled functions implement that interface which means you can inspect
the signature of the method that created them and discover its
generic types.
A bean of type FunctionRegistration registers the function with
user-specified name and other properties, rather than relying on the
bean name.
Alternatively, function catalog keys can be specified as a
@Qualifier, which will be used instead of the bean name if
no registration is found.
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
We don't need to cover all the possible uses of Flux (only
Flux<String> really), so this isn't comprehensive coverage of
all the features in Spring WebFlux, but it's good enough for
functions to run with Spring Boot 1.5.
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)
