Question

我目前需要使用Spring Boot来提供我的React应用程序。它适用于根URL - localhost:8080/，但当然没有一个子路由被Spring Controller识别。

我不确定如何在没有硬编码的情况下将React Routing和Spring请求映射排成一行，以映射到index.html - 然后一些路由具有可变的子路由。

以下是我HomeController

的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>
)

非常感谢任何帮助！

编辑：我尝试添加一些通配符功能，它呈现出一些奇怪的行为。以下是HomeController的更新代码。

@Controller
public class HomeController {

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

我可以访问/和/users但不能访问/users/或/users/2545。

当我尝试访问后者时出现错误。

Answer 1

对我来说，我在link中尝试了答案。我没有控制器。

基本上是关于定义addViewController ...

@Configuration
public class WebConfiguration extends WebMvcConfigurerAdapter {

  @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

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 "/";
    }
}

Answer 3

我有同样的问题，这个映射对我有用：

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

使用Spring Boot提供React App时出现React-Router问题
