React-Router issues when serving React App with Spring Boot

Question

I'm currently needing to serve my React app with Spring Boot. It is working for the root url - localhost:8080/, but of course none of the sub-routes are recognized by the Spring Controller.

I'm not sure how to get the React Routing and Spring request mapping to line up without hard-coding in every possible route to map to index.html - and then some of the routes have variable sub-routes.

Here is my HomeController that serves the index.html

@Controller public class HomeController {      @RequestMapping(value = "/")     public String index() {         return "index.html";     } }

Here is the Routing render in my React App

const Root = ({ store }) => (   <Provider store={store}>     <Router history={browserHistory}>       <Route path="/" component={App}>         <IndexRedirect to="users"/>         <Route path="/org" component={OrgSearch}>           {<Route path="/org/:orgId" component={Org}/>}         </Route>         <Route path="/users" component={UserSearch}>           {<Route path="/users/:userId" component={User} />}         </Route>       </Route>     </Router>   </Provider> ) 

---

Any help is greatly appreciated!

EDIT: I tried adding some wildcard functionality, and it is presenting some strange behavior. Here is the updated code for the HomeController.

@Controller public class HomeController {      @RequestMapping(value = {"/", "/users/**", "/org/**"})     public String index() {         return "index.html";     } } 

I can access / and /users but not /users/ or /users/2545.

Here is the error when I try to access the latter.

Answer 1

For me, I tried the answer in this link. I did not have a controller.

Basically it is about defining the addViewController...

@Configuration public class WebConfiguration implements WebMvcConfigurer {    @Override   public void addViewControllers(ViewControllerRegistry registry) {       registry.addViewController("/{spring:\\w+}")             .setViewName("forward:/");       registry.addViewController("/**/{spring:\\w+}")             .setViewName("forward:/");       registry.addViewController("/{spring:\\w+}/**{spring:?!(\\.js|\\.css)$}")             .setViewName("forward:/");   } } 

Answer 2

I had the same issue, and this mapping worked for me:

@RequestMapping(value = {"/","/users/{id}"})
