When using Springfox you can annotate your endpoints to automatically generate OpenAPI docs for your clients.
This blogpost will show how you can prevent Springfox generating a model on an endpoint with ResponseEntity as return type.
I’ll also cover how to prevent generating default responses.
Adding Spring Security to an existing application can be quite a daunting prospect. Merely adding the required dependencies to your project sets off a chain of events which can break your application and tests.
In a previous post I’ve shown how to use ZIO environments to provide your program with dependencies, or modules. While using environments at the customer I’m currently working for, we found out that the logic to get a database session object using a module would run over and again. This makes sense, since a ZIO[R, E, A] is a prescribed way of getting an A, and the result is not cached. Our application was reading configuration files and creating SQL sessions on every module call, while the resulting object was obviously constructed from the same underlying values. There are multiple ways to solve this:
When combined with Spring Security 5.2+ and an OpenID Provider such as Keycloak, one can rapidly setup and secure Spring Cloud Gateway for OAuth2 resource servers.
This is an overview of some optimization techniques used by Hotspot JVM to increase performance. I will start by giving a small example of how I ran into these optimizations while writing a naive benchmark. Each optimization is then explained with a short example and ends with some pointers on how to analyze your own code.
