如何使用React Router替换render方法中的组件？

import React from 'react';
import { BrowserRouter as Router, Route } from 'react-router-dom';

// 导入需要替换的组件
import Home from './components/Home';
import About from './components/About';
import Contact from './components/Contact';

const App = () => {
  return (
    <Router>
      <Route path="/" exact component={Home} />
      <Route path="/about" component={About} />
      <Route path="/contact" component={Contact} />
    </Router>
  );
}

export default App;
