Class RequestParameters

java.lang.Object
com.oorian.RequestParameters
All Implemented Interfaces:
Serializable
public class RequestParameters extends Object implements Serializable
Serializable wrapper for HTTP request parameters.

RequestParameters captures the parameter map from an HttpServletRequest at construction time, allowing the parameters to be accessed after the original request has been completed. This is essential for asynchronous processing and worker thread operations.

Key Features:

  • Serializable for session persistence and clustering
  • Type-safe accessors for Integer, Long, Float, and Boolean values
  • Support for multi-valued parameters
  • Default value support for missing parameters

Usage:


 RequestParameters params = new RequestParameters(request);
 Integer userId = params.getParameterAsInt("userId");
 String action = params.getParameter("action", "default");
 List<Long> selectedIds = params.getParameterValuesAsLong("ids");
