Reading JSON Documents as Maps and Comparing Them

Date: 2023-11-17

This article demonstrates how to convert JSON data into Java Maps using Jackson and Gson libraries, and then compares those maps. Both libraries efficiently parse JSON strings into Map objects. The article provides code examples showcasing this conversion, noting that Gson treats numbers as Doubles. For map comparison, it recommends using Apache Commons Lang's EqualsBuilder for reliable deep comparisons, especially with nested structures, unlike a simple equals() method. Understanding these techniques is crucial for efficient data processing and manipulation in Java applications.
