vuex中store分文件时候index.js进行文件整合

 import Vue from 'vue'
 import Vuex from 'vuex'
 Vue.use(Vuex);
 import getters from './getters.js'
 import actions from './actions.js'
 import user from './modules/user.js'
 export default new Vuex.Store({
     getters,
     actions,
     modules:{
         user
     }
 });
