react 跳转后路由变了页面没刷新的解决方案

 // 组件挂载
  componentDidMount() {
    console.log(this.props.location);
  }

 render() {
    return (
      {}
      <div key={this.props.location.key}>
          <Switch>
            <Route exact path="/" component={Home} />
            <Route exact path="/products/:id" component={Products} />
            <Route exact path="/about" component={About} />
            <Route exact path="/solution" component={Solution} />
            <Route
              exact
              path="/solutionDetails/:id"
              component={SolutionDetails}
            />
            <Route exact path="/download" component={Download} />
            <Route path="/about" component={Download} />
            <Route exact path="/details/:id" component={Details} />
            <Route path="/contact" component={Contact} />
            <Route component={ErrorPage} />
          </Switch>
      </div>
    );
  }

import React, { Component } from "react";
import {withRouter } from "react-router";

class routers extends Component {
 
 // 组件挂载
 componentDidMount() {
   console.log(this.props.location);

export default withRouter(routers);
