[SPRING] Add converters for enums by Zomzog · Pull Request #13349 · OpenAPITools/openapi-generator

Zomzog · 2022-09-04T21:31:06Z

We need to add converters because spring doesn't use jackson for path and query params (cf spring-projects/spring-boot#24233 )
This will fix #12874

PR checklist

Read the contribution guidelines.
Pull Request title clearly describes the work in the pull request and Pull Request description provides details about how to validate the work. Missing information here may result in delayed response from the community.
Run the following to build the project and update samples:
```
./mvnw clean package 
./bin/generate-samples.sh
./bin/utils/export_docs_generators.sh
```
Commit all changed files.
This is important, as CI jobs will verify all generator outputs of your HEAD commit as it would merge with master.
These must match the expectations made by your contribution.
You may regenerate an individual generator by passing the relevant config(s) as an argument to the script, for example ./bin/generate-samples.sh bin/configs/java*.
For Windows users, please run the script in Git BASH.
File the PR against the correct branch: master (6.1.0) (minor release - breaking changes with fallbacks), 7.0.x (breaking changes without fallbacks)
If your PR is targeting a particular programming language, @mention the technical committee members, so they are more likely to review the pull request.

Possible to avoid * ?

Fixed in the template

This will create an empty configuration file if there are no enums. Might be confusing to users who generate the project and then don't understand why this file exists - maybe conditionally add this file if there are any enums present?

I've added some code to check if there is an enum in the models.

@poulad FYI - might be of interest to you

Change looks great! Some generated code I wouldn't expect to see...

Your IDE seems to have added a lot of auto-formatting - you may want to disable that and/or revert that. Makes it hard to review

I removed them.

Is this generated? I don't see why your PR would be creating this...

I've rerurun all generators. I've fixed it by restarting from master.

        }
    }

+    private boolean containsEnums() {


Proposal for more better readability. WDYT?

private boolean containsEnum() { if (openAPI == null) { return false; } Components components = openAPI.getComponents(); if (components == null || components.getSchemas() == null) { return false; } return components.anyMatch(component -> component.getEnum() != null && !component.getEnum().isEmpty()); }

Also, further thinking about this, would be good to add unit tests for this method

I've added a test, but it's more a test-by-side-effect with the file creation.

+import org.springframework.core.convert.converter.Converter;
+
+@Configuration
+public class EnumConverters {


I would rename it to EnumConverterConfiguration

Additional the config is just working if you import it manually, activate component scan or create a auto config file. Documentation would be good, what is expected to work

I've changed the name.
What kind of documentation is expected? I suppose the scan is done as it is done for others @Configurationno?

probably this has to be smth like package {{package}}.configuration;

I change for {{configPackage}}

enums can have other data type except String. Note {{dataType}} for fromValu param

openapi-generator/modules/openapi-generator/src/main/resources/JavaSpring/enumClass.mustache

Line 42 in f3fa675

public static {{{datatypeWithEnum}}}{{^datatypeWithEnum}}{{{classname}}}{{/datatypeWithEnum}} fromValue({{{dataType}}} value) {

Ok, I've done the change.

nit - would expect method name to start with lowercase for Java convention

It's changed.

Any chance it can be merged?

Did this fix the issue #12874 for only springboot project or non-spring boot (java spring) project as well because I am using a non spring boot project and still facing the issue
