Express js session undefined

Question

server.js

var express=require('./config/express');
var app=express();
app.listen(3000);

expressjs

var express=require('express'),
        cookieParser = require('cookie-parser'),
        session=require('express-session');

var app=express();
    var routes=require('../app/routes/index.server.routes');
    routes(app);

    app.use(cookieParser());
        app.use(session({
            saveUninitialized: true,
            resave: true,
            secret: "This is a secret"
        }));

routes.js

module.exports=function(app){
    var indexController=require('../controllers/index.server.controller');
    app.get('/',indexController.render);
}

控制器

exports.render=function(request,response){
    if(request.session.lastVisit){
        console.log(request.session.lastVisit);
    }
    request.session.lastVisit=new Date();
    response.render('index',{
        model:'lokesh'
    })
}

错误

Cannot set property 'lastVisit' of undefined

我安装了所需的模块。它仍然无法创建会话。谁能指出错误。更新完整代码

注册中间件后注册路线：

var app=express();
var routes=require('../app/routes/index.server.routes');

app.use(cookieParser());
app.use(session({
    saveUninitialized: true,
    resave: true,
    secret: "This is a secret"
}));
routes(app);
