Springboot without session development

The session child Web project has been in existence since it appeared.

Recently in the development of the cluster project, think of session processing, between a session before doing a cluster processing

Spring-session-data-redis

This is a session management integrated with spring + Redis.

It's good to use, but it's a little inconvenient for managing the session.

So, I wrote a session to manage it myself.

Springboot Interceptor + Redis to intercept requests.

1. Determine if you are logged in

 Public Static BooleanIsLogin (HttpServletRequest request) {//Get Cookie valueString Cookievalue =Cookieutil.getcookievalue (Request, zipper_token_web_cookie_name); //The cookie value does not exist, indicating that it is not logged        if(Stringutil.isnullorempty (cookievalue)) {return false; }        //verifying the presence of a token value in a Redis expiresredisutil.strings s = redisutil.getinstance ().NewStrings (); if(!s.exists (Db_index, Gettokenexpireskey (cookievalue))) {            return false; }        //Update token time        LongR1 =S.expire (Db_index, Gettokenexpireskey (cookievalue), time_out); if(R1 = = 0) {            //hit failed, re-added cache valueS.setex (Db_index, Gettokenexpireskey (Cookievalue), Time_out, "");                } s.expire (Db_index, Gettokenkey (cookievalue), time_out_data); return true; }

2. User login, create token

 Public StaticString Createtoken (Usermodel record, list<menumodel>menulist) {        //Generate TokensUUID UUID =Uuid.randomuuid (); String token=uuid.tostring (); Redisutil.strings s= Redisutil.getinstance ().NewStrings (); Redisutil.hash h= Redisutil.getinstance ().NewHash (); //Set Expire tokenS.setex (Db_index, Gettokenexpireskey (token), time_out, ""); //set up data tokenString Tokenkey =Gettokenkey (token); Loginuser Loginuser=NewLoginuser (record);        H.hset (Db_index, Tokenkey, Login_user, loginuser.tostring ()); //Depending on the known code, menulist may be null        if(NULL!=menulist)        {H.hset (Db_index, Tokenkey, Menu_list, jsonobject.tojsonstring (menulist));                } s.expire (Db_index, Tokenkey, Time_out_data); //Return token        returntoken; }

After the user logs in successfully, the token exists in the cookie.

// Create token        String token = W.createtoken (Usermodel, menulist);         // Set Cookies         Cookieutil.setcookie (Request, Response,                w.zipper_token_web_cookie_name,                TOKEN, W.zipper_token_ Web_cookie_time_out);

3. User logoff, delete token

/**Delete according to token*/     Public Static BooleanDeletetoken (HttpServletRequest request) {//Get Cookie valueString Cookievalue =Cookieutil.getcookievalue (Request, zipper_token_web_cookie_name); if(Stringutil.isnullorempty (cookievalue)) {//token does not exist            return true; }                //Delete expire tokensredisutil.strings s = redisutil.getinstance ().NewStrings (); Long R=S.del (Db_index, Gettokenexpireskey (Cookievalue)); //Delete Data tokenRedisutil.hash h = redisutil.getinstance ().NewHash ();                H.hdel (Db_index, Gettokenkey (Cookievalue)); return(r = = 1); }

User logoff, delete token information

W.deletetoken (Request);

4. Get user information, menu information, etc.

/**Get login User Information*/     Public Staticloginuser Getloginuser (httpservletrequest request) {//Get Cookie valueString Cookievalue =Cookieutil.getcookievalue (Request, zipper_token_web_cookie_name); if(Stringutil.isnullorempty (cookievalue)) {//token does not exist            return NULL; } redisutil.hash H= Redisutil.getinstance ().NewHash (); String value=H.hget (Db_index, Gettokenexpireskey (cookievalue), login_user); if(Stringutil.isnullorempty (value)) {return NULL; }        returnJsonobject.parseobject (value, Loginuser.class); }        /**Get login User menu Information*/     Public StaticList<menumodel>getmenulist (HttpServletRequest request) {//Get Cookie valueString Cookievalue =Cookieutil.getcookievalue (Request, zipper_token_web_cookie_name); if(Stringutil.isnullorempty (cookievalue)) {//token does not exist            return NULL; } redisutil.hash H= Redisutil.getinstance ().NewHash (); String value=H.hget (Db_index, Gettokenkey (cookievalue), menu_list); if(Stringutil.isnullorempty (value)) {return NULL; }        returnJsonobject.parsearray (value, Menumodel.class); }

Redis Storage Fabric

In this way, a custom no-session management system has been developed.
