Jackson JSON Java: Parser API Examples & Tutorial

Published on August 3, 2022
πŸ‘ Jackson JSON Java: Parser API Examples & Tutorial

Jackson JSON Java Parser is very popular and used in Spring framework too. Java JSON Processing API is not very user friendly and doesn’t provide features for automatic transformation from Json to Java object and vice versa. Luckily we have some alternative APIs that we can use for JSON processing. In last article we learned about Google Gson API and saw how easy to use it.

I would just like to add I had to use the @JsonProperty & @JsonCreator annotations to read the json back into my model using the ObjectMapper. Otherwise I would get instantiation errors. -Also I am using the β€œcom.fasterxml.jackson” libraries.

Pankaj, I’m just taking some time to express my gratitude for you do share so many well-written articles, specially this one. I’ve been googling back to this specific article for so many times I’ve already bookmarked it. Thanks a lot, I really appreciate it.

Very useful article. Jackson API in itself is very beneficial and the process of using JsonGenerator has made it even more simple. I had been stuck with json auto-formatting and Jackson has been a wonderful support and your samples helped a lot. Cheers !!
