Convert Java Object To / From JSON, Jackson Example explains about converting a Java Object to JSON string, JSON string to Java Object Using Jackson JSON library

Consider an example where you need to pass the request as JSON string, In this situation you can easily serialize the Java Object to JSON string and vice versa

According to Jackson documentation, Jackson is a multi-purpose Java library for processing JSON data format. Jackson aims to be the best possible combination of fast, correct, lightweight, and ergonomic for developers.

CXF Convert Number To String explains about resolving the issue on serialization when the value of a string is integer when using jettison library

Jettison is an open source java library for processing JSON format. It is the default library bundled with CXF framework, the problem with jettison is that if value of a string is integer type, it automatically convert that string to integer type. By removing the quotes between that number

if the string values is "12345"
{"Student":{"name":"12345"}}
it automatically convert to below value
you can see that quotes are removed even the type of that object is string
{"Student":{"name":12345}}
