1. 首先创建Router/index.js，eg：包含Home和Login

import Home from '../Pages/Home/Home.jsx'
import Login from '../Pages/Login/Login.jsx'

let routes = [
    {path: '/', component: Home, exact: true},
    {path: '/login', component: Login},
]

export default routes

2. 在App.js中引入：

import React, { Component } from 'react';
import { BrowserRouter as Router, Route, Link } from 'react-router-dom';
import routes from './Router/index'

// 路由页面
import Home from './Pages/Home/Home.jsx';
import Login from './Pages/Login/Login.jsx';

class App extends Component {
    constructor(props) {
        super(props);
        this.state = {  }
    }
    render() { 
        return (
            <Router>
              <ul className="topBar">
                <li><Link to="/">Home</Link></li>
                <li><Link to="/login">Login</Link></li>
              </ul>
              {
                routes.map ((route, key) => {
                  // console.log(route)
                  if(route.exact) {
                    return (
                      <Route 
                        key = {key} 
                        exact
                        path = {route.path} 
                        render = {props => (
                          <route.component {...props} />
                        )}
                      />
                    )
                  }else{
                    return (
                      <Route 
                        key = {key} 
                        path = {route.path} 
                        render = {props => (
                          <route.component {...props} />
                        )}
                      />
                    )
                  }
                })
              }
            </Router>
        );
    }
}
export default App;

到此，动态路由配置完成。
