spring - 当“无法解析带有名称的视图”时如何隐藏打印信息？

Question

我正在使用 freemaker，我编写了一个视图求解器类，如下所示：

@GetMapping("/**/{name}.html")
public String mapPath() {
    return getRequest().getRequestURI().split("\\.")[0];
}

使用这种方法，我可以轻松地在模板目录中查看我的页面。但问题是此方法将匹配所有带有“.html”的页面，包括不存在的页面。如果是这样，每次访问那些不存在的页面时，控制台都会打印异常，例如

我已经知道这个异常，我想隐藏这个令人厌烦的异常。我该怎么做？

我曾尝试过@ExceptionHanlder 和@ControllerAdvice 的全局异常处理程序，但它没用。

有人能帮我吗？
