Class ThreadLocalSessionData

java.lang.Object
io.jmix.core.impl.session.ThreadLocalSessionData
public class ThreadLocalSessionData extends Object
Provides thread-local storage for session attributes. This utility class facilitates the transfer of HTTP session data to newly spawned threads that do not inherently have access to the data of the original HTTP session.

Use this class when you need to perform operations in a new thread that require access to the session data from an HTTP request. This is particularly useful in asynchronous processing or when handling requests outside the main request processing thread.

Usage example: 

 Map<String, Object> sessionAttributes = ThreadLocalSessionData.extractHttpSessionAttributes();
 ThreadLocalSessionData.setAttributes(sessionAttributes);
 // Now, session attributes can be accessed from the new thread using ThreadLocalSessionData.getAttribute(...)

Ensure that you clear the thread-local storage after use. Use clear() method once the thread-local data is no longer needed.
