Reactjs react路由器1.0.0-rc3-所有URL仅映射到一个react组件

我有以下路线：
routes.jsx

var routes = (
    <Route component={AfApp} path="/">
        <Route path="/testpage" component={Test}/>
        <Route path="testpage" component={Test}/>
    </Route>
);

module.exports = routes;

import routes from './routes.jsx';
ReactDOM.render(<Router routes={routes} />, document.getElementById('content'));

import createBrowserHistory from 'history/lib/createBrowserHistory';
ReactDOM.render(<Router history={createBrowserHistory()} routes={routes} />, document.getElementById('content'));

entry.jsx

var routes = (
    <Route component={AfApp} path="/">
        <Route path="/testpage" component={Test}/>
        <Route path="testpage" component={Test}/>
    </Route>
);

module.exports = routes;

import routes from './routes.jsx';
ReactDOM.render(<Router routes={routes} />, document.getElementById('content'));

import createBrowserHistory from 'history/lib/createBrowserHistory';
ReactDOM.render(<Router history={createBrowserHistory()} routes={routes} />, document.getElementById('content'));

由于某些原因，我不明白添加历史记录（当然我必须运行

npm安装历史记录

）会使问题消失：
entry.jsx

var routes = (
    <Route component={AfApp} path="/">
        <Route path="/testpage" component={Test}/>
        <Route path="testpage" component={Test}/>
    </Route>
);

module.exports = routes;

import routes from './routes.jsx';
ReactDOM.render(<Router routes={routes} />, document.getElementById('content'));

import createBrowserHistory from 'history/lib/createBrowserHistory';
ReactDOM.render(<Router history={createBrowserHistory()} routes={routes} />, document.getElementById('content'));

从'history/lib/createBrowserHistory'导入createBrowserHistory；
ReactDOM.render（，document.getElementById（'content'））；
