OpenApi generator java-vertx-web where to put business logic

Question

I am trying out the java-vertx-web yaml to code generator. The generation process works fine and i get the code in target/generated-sources/openapi/src/gen/java/main/org/openapitools/vertxweb/server/api.

There are files called:

TestApiHandler.java
TestApiImpl.java
TestApi.java

Where in TestApiImpl there is for every route a stub method "NOT IMPLEMENTED", which is expected.

Now I thought the normal process would be to create in my own project files that extend these TestApiImpl files and write my own business logic in there so that they are in source control.

But when I do this there is no way for me to inject those new implemented classes back into the generated server, so that when routes are called not the stub methods are called, but my real implementations.

Overwriting the logic in these generated Impl classes makes no sense to me since this target folder is not in source control and every time I would regenerate my API these files would be overwritten.

What am I missing?

Add --ignore-file-override .openapi-generator-ignore flag after you generate the code for the first time.

.openapi-generator-ignore should have something like this

**/*Impl.java

This should prevent the generated code from overriding your business logic.
