创建index.js

const files = require.context('../components', true, /\.jsx$/);
const pages = [];
files.keys().forEach(key => {
    let i = key.replace(/(\.\/|\.jsx)/g, '');
    if(i !== 'index'){
        let component = files(key).default;
        let path = i.indexOf('/index') !== -1 ? i.split('/index')[0] : i;
        pages.push({
            path,
            component
        });
    }
});
export default pages;

创建router.js

import React from 'react';
import {Switch, Route } from 'react-router-dom';
import Pages from './index';

/* 视图组件 */
import Index from '../components/index';

class RouteIndex extends React.Component {
    render() {
        console.log(Pages);
        return (
            <Switch>
                <Route path="/" exact component={Index}></Route>
                {
                    Pages.length > 0 && Pages.map((item, index) => {
                        return (
                            <Route
                                key={index}
                                exact
                                path={`/${item.path}`}
                                component={item.component}
                            />
                        )
                    })
                }
            </Switch>
        );
    }
}
export default RouteIndex;
