How to Accept and Produce JSON as a response in Spring Boot? Example Tutorial

Hello everyone, welcome to the blog post. In this short tutorial, we are going to take an in-depth look at how to consume and produce JSON responses using a widely appreciated Java framework i.e. Spring Boot. As we all know Spring Boot is a framework designed to build a secure web application, microservice, REST API, and production-ready spring application. Modern-day application deals in a large amount of data, which they share in JSON format. A JSON is a standard plain text-based representation of structured data. It is one of the popular formats for data transmission over the internet. Due to its user-friendly syntax and lightweight, it helps in the process faster. 

How to convert JSON to Map in Java 8 without using third party libraries like Jackson or Gson

Hello guys, If you are working with JSON data then you may know that JSON is collection of key value pairs and that's why many times, you also need to convert them into a Map in Java. While there are many Java libraries like Jackson and Gson which provides support of parsing JSON to Java objects, there is not much support for JSON parsing or manipulation on standard JDK. While JSON parsing is still a long overdue, starting with JDK 8u60+ the built-in Nashorn engine is capable to convert JSON content into java.util.Map. No external dependencies are required for parsing JSON in to Map as you will learn in this article. 

How to convert JSON String to Java Object using Gson? JSON Deserialization Example

Hello Java Programmers, In the last article, you have learned how to convert a Java object to JSON String and in today's article, you will learn the opposite, i.e. converting a JSON String to a Java object. The first example was known as JSON serialization example and this one is known as JSON deserialization because we are creating a Java object from a String. The idea is very similar to classical Serialization in Java where you convert a Java object to another binary format that can be transported over the network or can be saved in the disk for further usage.
