[BUG][JAVA][SPRING] EnumConverterConfiguration does not use `modelNameSuffix` #14302

Open tschaffter opened 1 year ago

tschaffter commented 1 year ago

Bug Report Checklist

Description

OpenAPI generator generate the file EnumConverterConfiguration.java if the OA description includes at least one enum. The template does not take into account the generator configuration property modelNameSuffix, which is used to name the DTO models. The issue is then that the class EnumConverterConfiguration includes incorrect references to the DTO models.

openapi-generator version

6.2.1

OpenAPI declaration file content or url

See this OpenAPI description (note the use of enum)

A solution is to update the template converter.mustache to replace {{name}} by {{classname}}.

Before

package {{configPackage}};

{{#models}}
    {{#model}}
        {{#isEnum}}
import {{modelPackage}}.{{name}};
        {{/isEnum}}
    {{/model}}
{{/models}}

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.convert.converter.Converter;

@Configuration
public class EnumConverterConfiguration {

{{#models}}
{{#model}}
{{#isEnum}}
    @Bean
    Converter<{{{dataType}}}, {{name}}> {{classVarName}}Converter() {
        return new Converter<{{{dataType}}}, {{name}}>() {
            @Override
            public {{name}} convert({{{dataType}}} source) {
                return {{name}}.fromValue(source);
            }
        };
    }
{{/isEnum}}
{{/model}}
{{/models}}

}

After

package {{configPackage}};

{{#models}}
    {{#model}}
        {{#isEnum}}
import {{modelPackage}}.{{classname}};
        {{/isEnum}}
    {{/model}}
{{/models}}

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.convert.converter.Converter;

@Configuration
public class EnumConverterConfiguration {

{{#models}}
{{#model}}
{{#isEnum}}
    @Bean
    Converter<{{{dataType}}}, {{classname}}> {{classVarName}}Converter() {
        return new Converter<{{{dataType}}}, {{classname}}>() {
            @Override
            public {{classname}} convert({{{dataType}}} source) {
                return {{classname}}.fromValue(source);
            }
        };
    }
{{/isEnum}}
{{/model}}
{{/models}}

}

@tschaffter please try latest 6.3.0-SNAPSHOT

tschaffter commented 1 year ago

It doesn't look like the snapshot version is on Maven:

$ nx openapi-generate openchallenges-organization-service

> nx run openchallenges-organization-service:openapi-generate

Download 6.3.0-SNAPSHOT ...

@tschaffter 6.3.0 is not released yet & 6.3.0-SNAPSHOT is not available on maven central. Seems like CLI is now aware about snapshot versions

6.3.0-SNAPSHOT can be taken from here https://oss.sonatype.org/content/repositories/snapshots/org/openapitools/openapi-generator-cli/6.3.0-SNAPSHOT/ (information taken from https://github.com/OpenAPITools/openapi-generator#11---compatibility)

Seems like CLI has an option to customize maven repository which might help you. Check this please https://github.com/OpenAPITools/openapi-generator-cli#using-custom--private-maven-registry

Note: I haven't tried this, so might not work
