使用 Spring Boot 提供 React App 时的 React-Router 问题

我目前需要使用 Spring Boot 为我的 React 应用程序提供服务。它适用于根 url - localhost:8080/,但当然 Spring Controller 无法识别任何子路由。

我不知道如何让 React Routing 和 Spring 请求映射在没有硬编码的情况下在要映射到的每个可能的路由中对齐index.html- 然后一些路由具有可变的子路由。


这是我的HomeController服务index.html

@Controller
public class HomeController {

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

这是我的 React App 中的路由渲染

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>
)

任何帮助是极大的赞赏!


编辑:我尝试添加一些通配符功能,但它呈现出一些奇怪的行为。这是HomeController.

@Controller
public class HomeController {

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

我可以访问/and/users但不能访问/users/or /users/2545

这是我尝试访问后者时的错误。

对我来说,我尝试了这个链接中的答案我没有控制器。

基本上它是关于定义 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:/");
  }
}

我有同样的问题,这个映射对我有用:

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

我遇到了类似的问题,并通过将带有“**”的 URL 分离为单独的带注释的方法来解决它,例如:

@Controller
public class HomeController {

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

    @RequestMapping(value = {"/users/{**}"})
    public String users() {
        return "/";
    }

    @RequestMapping(value = {"/org/{**}"})
    public String org() {
        return "/";
    }
}
