Servletactioncontext Accessing the servlet API

Accessing the servlet API using Servletactioncontext

The action accesses the Servlet API and accesses the Servlet API through Ruquest, session, and Applicplition.

The SERVLETAPI that the city needs to visit in Web applications are HttpServletRequest, HttpSession, and ServletContext

These three interfaces represent the request, session, application of the built-in objects in the JSP, respectively.

Struts 2 provides a actioncontent class that can be accessed by the action of Struts 2 through this class Servletapi

in order to have direct access to the Servlet Api,struts 2 also provides a Servletaction tool class that contains the following static methods

return value		function description
httpservletrequest	getrequest ()	get HttpServletRequest objects for Web Apps
httpservletresponse	getresponse ()	get HttpServletResponse objects for Web Apps
servletcontext	getservletcontext ()	get ServletContext object for web App
PageContext	Getservletcontext ()	Get the ServletContext object for your web App

       With the help of the Servletactioncontext tool class, action can access the servlet API in a much simpler way.

public class Baaction extends Actionsupport implements Sessionaware,requestaware {@Overridepublic void setsession ( Map<string, object> session) {this.session = Session;httprequest = Servletactioncontext.getrequest (); context = Httprequest.getsession (). Getservletcontext (); response = Servletactioncontext.getresponse ();}}
