org.apache.struts2.json.StrutsJSONReader

All Implemented Interfaces:

JSONReader

public class StrutsJSONReader
extends Object
implements JSONReader

Deserializes an object from a JSON string with configurable limits to prevent denial-of-service attacks via malicious payloads.

This reader keeps per-parse state in instance fields and is not thread-safe; obtain a fresh instance per parse (the container serves it as a prototype bean). See WW-5650.
