问题
I'm new to the community. I built an e-commercce application with the Jhipster (Java + React Redux) Monolitica. I have the following problem: The application is configured to display a hashtag (#) in the URL for example ... http://localhost:9000/#/. I removed this parameter in React and everything was right. But when I upload the application with Gradle (./gradew) it works, http://localhost:9000/. But if you type directly into the browser http://localhost:9000/home/ I get ERROR 404, Page not found! -----> my application to check the problem (http://www.severobalanceboard.eco.br - OK), (http://www.severobalanceboard.eco.br/historia - ERROR 404) _
I think this problme by Spring.

Resolved, for remove Hash tag # To URL, using Jhipster and React [Spring + ReactJs]. I use the link of @Gaël Marziou told me.
follows the modifications:
==React==
1 - com/mycompany/myapp/src/main/webapp/app/app.tsx
import { BrowserRouter as Router } from 'react-router-dom'; 
// import { HashRouter as Router } from 'react-router-dom';
2 - com/mycompany/myapp/src/main/webapp/index.html
<!-- <base href="./"/> -->
<base href="/"/> 
3 - com/mycompany/myapp/webpack/webpack.prod.js
},
  devServer: {
    historyApiFallback: true, /*insert this line - only use for develop*/
    stats: options.stats,
    hot: true,
    contentBase: './build/www',
    proxy: [{
      context: [
...
==JAVA==
4 - com/mycompany/myapp/src/main/java/br/com/MyApp/config/WebConfigurer.java

    public Html5RouteFilter html5RouteFilter() { 
        return new Html5RouteFilter();
