这是React和Spring相对简单的组合，在这个论坛和其他论坛上有很多例子。我有两个配置文件：dev和prod。当我使用dev构建时，React在端口3000上，Spring在8080上运行。我正在使用Okta进行身份验证，一切都按预期进行。我可以与所有页面交互。然而，当我使用prod概要文件构建时，问题就开始了。应用程序在端口8080上启动。我进入主页并获得用户身份验证。在那之后，我被重定向到我的自定义错误页面。
这真的很令人沮丧，我的js构建将所有文件转储到target/classes/public(这是我所期望的(，当我检查时，这也是我的.jar文件中的内容
这是我的应用程序.js。所以，当我们在8080 端口上时，除了主页之外，什么都没有

答案是添加一个额外的控制器：
@Controller
class PageController {
@GetMapping("/**/{path:[^\.]*}")
fun forward(request: HttpServletRequest): String? {
if(request.requestURI.startsWith("/admin")) {
return "forward:/admin/index.html"
}
return "forward:/index.html"
}
}
这恰好是问题的答案为SPA前端配置Spring Boot
