我认为这里的问题是，所用样式表和图像的路由适合控制器路由{ratingId}/{latestRating}。这就是为什么我的控制器需要字符串和整数，但在请求样式表时会得到两个字符串，例如localhost:8080/styles/style.css。通过对所提到的控制器路由使用PostMapping，我可以解决这个问题。

在堆栈跟踪中可以看到错误的来源。您可能有一个映射捕捉到了这一点（可能是路径映射）。您说当您单击其中一个图像时会发生错误。因此，您必须在onclick=“rate（5）”处检查rate方法。其中一个图像正在发送一个无法转换为数字的字符串（例如“style.css”）。还向我们展示rate方法。函数rate（value）{document.location.href=ratingId+“/”+value；}做得不多您可以为此放置github项目吗？这样就可以复制？我能看出我的观察是正确的，解决方案最终解决了它
