CAMEL-11006 Auto generate REST DSL for Camel from Swagger2.0/OAI
specification
Submitting for review, thanks :1st_place_medal:
This is initial work on REST DSL code|object generation from Swagger
specification.
Entry point to the implementation is RestDslGenerator::generate(...)
methods. Several options are provided for generating source files:
- for code generation in Maven plugin ones accepting Path or Appendable
should be suitable
- for generation in Annotation Processing ones accepting Filer are more
appropriate
- and for generation of the object graph in runtime the one accepting
CamelContext is provided
Both the source code and object graph implementation depend on a
CodeEmitter implementation: one relying on reflection (RestDefinitionEmitter)
is used to generate the object graph, and the one generating the source code
for the RouteBuilder::configure method body using the javapoet library
(MethodBodySourceCodeEmitter).
CodeEmitter is driven by two visitor pattern implementations one for
processing path elements of the specification (RestDslPathGenerator) and one
for processing operation elements of he specification
(RestDslOperationGenerator). Both can be further adapted to support more of
the Swagger specification. I believe they map the currently used / relevant
parts of the Swagger specification covered by REST DSL.
