Swagger codegen generate too long string literals

问题

I need to generate classes based on provided swagger file. Unfortunately I have no influence on content of this file.

My config in gladle looks like:

task generateApi {
doLast {
    def config = new CodegenConfigurator()
    config.setInputSpec("file:///$projectDir/$swaggerSourceFile")
    config.setOutputDir("$projectDir/$swaggerTargetFolder")
    config.setLang('spring')
    config.setAdditionalProperties([
            'interfaceOnly'       : true,
            'apiPackage'          : 'somepackage',
            'modelPackage'        : 'somepackage.domain',
            'sourceFolder'        : '',
            'java8'               : true,
            'dateLibrary'         : 'java8',
            'skipDefaultInterface': true
    ])
    new DefaultGenerator().opts(config.toClientOptInput()).generate()
}
}

Exception which I`m getting is : "error: constant string too long"

Problem is that even I set 'skipDefaultInterface', swagger will generates it. In default interface it generates default response entity body which is json file which is 70k char long string.

Please help!

Looks like this is a known issue with the spring generator in Swagger Codegen:
https://github.com/swagger-api/swagger-codegen/issues/9055

A PR for this issue is available but not yet merged (as of February 2020):
https://github.com/swagger-api/swagger-codegen/pull/8691

Try using openapi-generator v. 4.2.2 or later which is supposed to include a similar fix.
