openapi-processor/openapi-processor-spring#132, fixed missing bean validation on request body

the processor did not always generate proper bean validation annotations on a parameter/request body. In the example below the @Size() annotation was missing on the request body array with size constraints:

openapi-processor-mapping: v2

options:
  # ...
  bean-validation: true

map:
  types:
    - type: array => java.util.List

  ...

  requestBody:
    content:
      application/json:
        schema:
          type: array
          items:
            type: string
            minLength: 2
            maxLength: 2

  ...

public interface Api {

    @PostMapping(path = "/foo", consumes = {"application/json"})
    void postFoo(@RequestBody(required = false) List<@Size(min = 2, max = 2) String> body);

}

This fix includes a general change in the annotation order. The bean validation annotation moved nearer to the parameter type behind the mapping annotations. (Note that @Parameter is just a placeholder for the Spring/Micronaut mapping annotations)

before

    @Mapping("/items")
    void getItems(
            @Size(min = 2) @Parameter String[] min,
            @Size(max = 4) @Parameter String[] max,
            @Size(min = 2, max = 4) @Parameter String[] minMax);

after

    @Mapping("/items")
    void getItems(
            @Parameter @Size(min = 2) String[] min,
            @Parameter @Size(max = 4) String[] max,
            @Parameter @Size(min = 2, max = 4) String[] minMax);
