jackson-module-scala VS DSL-JSON

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?

As a workaround you can turn on ignoring of unknown properties on the level of object mapper instance like here, but beware in case your system accepts an untrusted input because it turns on DoS vulnerability.

The simplest JSON parsing library is Jackson.

https://github.com/FasterXML/jackson-module-scala specifically

I've updated results of benchmarks of 12 JSON parsers for Scala: - AVSystem's scala-commons - Borer - Circe - DSL-JSON - Jackson - jsoniter-scala - Play-JSON, - play-json-jsoniter - Spray-JSON - uPickle - weePickle - zio-json

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.

You gotta at least add the top contender. I mean dsl-json is probably the fastest json lib java has to offer. I personally like Rob's avaje-jsonb, because I think the approach of no reflection, and doing everything via annotation processing is rad. (it also has some decent speed too)

Have you tried dsl-json instead of jsoniter? Should be faster.
