I found some "tricks" to write less code, hence less code to maintain if there are any changes. Also less code with bugs just by changing the inputs.
For example, OpenAPI spec file + OpenAPI generator (https://github.com/OpenAPITools/openapi-generator). Any changes in the OpenAPI spec are reflected in the final code with a build step.
Another example: MapStruct (https://mapstruct.org/) to avoid passing data from Entity classes to DTO and back. Saves looots of boilerplate code.
Which are your tricks?
Project mention: Double-Take not getting enough events/images from Frigate? | /r/frigate_nvr | 2023-08-01# https://github.com/exadel-inc/CompreFace/blob/master/docs/Face-services-and-plugins.md)
The issue is that the springdoc-openapi BOM brings an old version of the Spring Framework 6.0, which is incompatible with Spring Boot 3.2. There are several ways to solve this problem: update springdoc, change the order of BOM imports, but the best, in my opinion, is to avoid using the io.spring.dependency-management plugin.
Project mention: Spring Boot 3 application on AWS Lambda - Part 3 Develop application with AWS Serverless Java Container | dev.to | 2024-04-15The key dependency to make it work and translate between Spring Boot 3 (web annotation) model and AWS Lambda is the dependency to the artifact aws-serverless-java-container-springboot3 defined in the pom.xml. It's based on Serverless Java Container which natively supports API Gateway's proxy integration models for requests and responses, and we can create and inject custom models for methods that use custom mappings.
I haven't used either of these two suggestions, but with some quick searching, I found MyCollab or Fractale which look like they might be pretty good. MyCollab looks better of the two of those to me, but Fractale could surprise me.
