  Using Circe so I define some classes that contain my custom Encoder[BusinessObject] in a file and I use that whenever I want to save/store a record, or handle a web request or respose. I also represent my mongo queries as JSON objects that I can freely build then pass to the driver.

  Project mention: The Newest Java Json Benchmark Results just dropped | /r/java | 2023-05-01

  Afaik dsl-json came up with a lot of improvements and inspired a several other libraries like JsonIter and jsonIter-scala. Jsoniter-scala by u/plokhotnyuk is probably the most optimized JSON library on the JVM at this point, and seems to power most of the Scala ecosystem. Some implementations/optimizations eventually made their way back into Jackson and other libraries.

  The other comment is asking the right questions. But also how is it failing? Do you have an error message? Is JsonUtil part of Jackson? Do you need to be using https://github.com/fasterxml/jackson-module-scala with an object mapper?
