Generated API method name without prefix, postfix

[MartinMilata]

Good morning,
my swagger json is without operationId.. (I cannot change it, it is from external company).. It looks this way:
And method generated by openapitool looks this way: backEndAdministrationGetTenantRolesAndGroupsPost.
Is there any way, any customization, that method would have name like GetTenantRolesAndGroups?

You can use operationIdNameMappings as described at https://openapi-generator.tech/docs/customization/

External Backend server has hundreds of methods, and I do not want for every method name operationIdNameMappings... Is it possible, to somewhere say: Method name at backend is GetTenantRolesAndGroups, so I want to generate the method name the same, without prefix backEndAdministration and postfix Post.

You can use a verbose output and parse the output with some regex/scripting

https://github.com/openapitools/openapi-generator/blob/master/docs/customization.md#name-mapping

To map operationId (used in method naming) to something else, use operationIdNameMappings option, e.g.

java -jar modules/openapi-generator-cli/target/openapi-generator-cli.jar generate -g java -i modules/openapi-generator/src/test/resources/3_0/petstore.yaml  -o /tmp/java/ --operation-id-name-mappings getPetById=returnPetById

Thank you for response, do you mean to do "renaming" generated method myself by my script? If there is no option, so this is last option, but much easier would be, if openapitool would have option to generate methods without prefix and postfix by some configuration....
to Wint328 - I am repeating, External Backend server has hundreds of methods, and I do not want for every method name operationIdNameMappings... Is it possible, to somewhere say: Method name at backend is GetTenantRolesAndGroups, so I want to generate the method name the same, without prefix backEndAdministration and postfix Post.

openapi geneator is open source. You can maintain a fork version of openapi generator and customize how operationId is auto-generated when it's not provided in the spec
