Requestattributes RA = requestcontextholder.getrequestattributes ();  HttpServletRequest request = ((servletrequestattributes) RA). Getrequest ();  Request.getsession (). SetAttribute (name, webuser);

Note: 30 Finger minutes

You can also have all control inherit a Basecontrol class, and the Basecontrol class is defined as:

Package Com.jrgy.web.controller;import Java.io.serializable;import Java.util.arraylist;import java.util.HashMap; Import Java.util.list;import Java.util.map;import Javax.servlet.http.httpservletrequest;import Javax.servlet.http.httpsession;import Org.springframework.beans.factory.annotation.autowired;import Org.springframework.web.context.request.requestattributes;import Org.springframework.web.context.request.requestcontextholder;import Org.springframework.web.context.request.servletrequestattributes;import Com.jrgy.pojo.domain.FriendlyLink; Import Com.jrgy.pojo.domain.iteminfo;import Com.jrgy.pojo.domain.webuser;import Com.jrgy.util.cachemanager;import Com.jrgy.util.constants;import Com.jrgy.web.service.iassociationmanager;import Com.jrgy.web.service.iwebindexmanager;import Com.jrgy.web.service.iwebiteminfomanager;public class BaseController Implements Serializable{private static final long serialversionuid = 8695834026800952113l;/** *???? * */////HTTPSERVLETR Equest request = ((Servletrequestattributes) Requestcontextholder//.getrequestattributes ()). Getrequest (); CacheManager CacheManager = Cachemanager.getinstance (); @AutowiredIWebIndexManager webindexmanager;@ Autowirediwebiteminfomanager Webiteminfomanager; @AutowiredIAssociationManager webassociationmanager;/** * navigation bar * */ list<iteminfo> listiteminfo = new arraylist<iteminfo> ();/** * Links * */list<friendlylink> FRIENDLYLINKLS = new arraylist<friendlylink> (); List Itmecode = new ArrayList (); Map map = new HashMap ();/** *?????????? * @param Object???????? * @param String KEY? * @return Object * @throws Exception */public Object GetCache (Object object, String key) {Object cachedate = CacheManager. Get (key); if (cachedate! = null) {object = Cachedate;} return object;} /** * * @param key * @param object * @return void * @throws Exception */public void Addcache (String key, Object object) { Cachemanager.delcachebykey (key); Cachemanager.add (Key, object);} public void Addsessionwebuser (String name,webuser WebUser) {Requestattributes RA = requestcontextholder.getrequestattributes ();  HttpServletRequest request = ((servletrequestattributes) RA). Getrequest (); Request.getsession (). SetAttribute (name, webuser);} Public Object Getwebuserattribute (String name) {//TODO auto-generated method stubrequestattributes ra = Requestcontextho  Lder.getrequestattributes ();  HttpServletRequest request = ((servletrequestattributes) RA). Getrequest (); Object obj=null;if (!name.trim (). Equals ("")) {obj= request.getsession (). getattribute (name);} return obj;}}

This makes it easy for each control to get the objects in the servlet API.

Login save User to session

@RequestMapping ("/islogin.do") public void IsLogin (HttpServletRequest request, httpservletresponse response) {String SessionId = Request.getsession (). GetId (); Response.setcontenttype ("Text/html;charset=utf-8"); String userName = Request.getparameter ("UserName"); String PassWord = Request.getparameter ("UserPassword"); WebUser webuser=new WebUser (); String MSG = null;try {if (! Strutil.checkstr (UserName)) {msg= "2";} else if (! Strutil.checkstr (PassWord)) {msg= "3";} Else{webuser=mainwebusermanager.userlogin (Username,password); if (webuser!=null) {if ( Constants.webUserStruts.equals (Webuser.getwebusertype ())) {MSG = "5";} else{msg = "1"; Addsessionwebuser (Constants.login_webuser,webuser); Log.debug (username+ "");}} else{msg = "4";}} PrintWriter out = Response.getwriter (); String outmsg = "{Msg:" +msg+ "}"; Out.print (outmsg); Out.flush (); Out.close ();} catch (Exception e) {e.printstacktrace ();}}

The following code is required to use the session:

                String Name=constants.login_webuser; WebUser web= (WebUser) getwebuserattribute (name), if (web!=null) {currentuser=web.getwebusername ();}
