Custom template to add annotation for spring data

In model class generated I want some annotation to be generated for it to persist in db using spring data. Used template but I can only put static code if want to introduce some dynamic param like {{#myanotation}} then can specify from properties or .yml file it would be great

java -jar swagger-codegen-cli-2.2.1.jar generate -i api.yml -c conf.json -l spring -o %TMP_SRC_DIR% -t C:\Users\template

api.yml --> yaml for apis as we as models
%TMP_SRC_DIR% --> output directory any
template folder had model.mustache and api.mustache which I want to modify

Scenario want to generate required set of files as dont want to change model classes manually

Start with the custom model.mustache and api.mustache templates referenced in the issue, then inspect how conf.json and the spring generator process template values during the swagger-codegen-cli generate command. The requested behavior is dynamic annotation content for generated model classes, supplied through configuration or a YAML file; done means the generated models contain the requested annotations without manual edits.
