Contributions summary:Simon primarily contributed to the Spring-boot server application code generation process. They added and modified configuration keys, specifically related to default interface generation in both Spring and Spring2 code generation templates. Furthermore, they updated the code to write properties back to a config file and mapped the "binary" format to the "Resource" type. These changes indicate work on improving the application's flexibility and data handling capabilities within the context of code generation using the Swagger tools.
