This application has no explicit mapping for /error, so you are seeing this as a fallback.

这个报错的原因是你在InquiryController类中定义了一个@GetMapping("/form")的方法，但是对应的URL请求方式是GET方法。而你在浏览器中访问该URL时使用的是POST方法，所以导致报错。
要解决这个问题，有两种方法：
1. 将浏览器中的请求方式改为GET方法。在浏览器中直接输入对应的URL，不要使用表单提交请求。
2. 修改InquiryController类中的@PostMapping("/form")方法为@GetMapping("/form")，即将POST请求改为GET请求。
修改后的代码如下：
@GetMapping("/form")
public String formGoBack(InquiryForm inquiryForm, Model model) {
model.addAttribute("title", "Inquiry Form");
return "inquiry/form";
}
这样修改之后，在浏览器中访问对应的URL时就可以正常显示页面了。
以上回复来自 FishC AI 小助理，如未能正确解答您的问题，请继续追问。 如果实在拿不准请求方式，直接使用@RequestMapping()
