Project mention: Consuming and Testing third party API's using Spring Webclient | dev.to | 2024-02-19The above class maps the json data to a java object we can work with.

We know the response is an array of objects representing the coffee and so above data structure is fit for this.
Project mention: Any library you would like to recommend to others as it helps you a lot? For me, mapstruct is one of them. Hopefully I would hear some other nice libraries I never try. | /r/java | 2023-05-27I like to use AutoService to make using Java's ServiceLoader easier.
