嗨我试图找出为什么我的jsp页面中的按钮没有映射到控制器方法。当我点击按钮时，它显示404不可用。
继承人jsp链接 -
<a href="/aucConfirm/${newAuction.idauction}/start" >Start Auction</a>
此控制器方法将拍卖项目添加到“newAuction” -
@RequestMapping(value = "/aucConfirm/{idauction}", method = RequestMethod.GET)
public String confirmAuction(@PathVariable(value = "idauction") int idauction, Model model, HttpServletRequest request) {
AuctionItem addAuction = (AuctionItem) aucRepository.findOne(idauction);
model.addAttribute("newAuction", addAuction);
model.addAttribute("startAction", addAuction.getIdauction() + "/start");
return "aucConfirm";
}
这是链接应映射到的控制器方法 -
@RequestMapping(value = "/aucConfirm/{idauction}/start", method = RequestMethod.GET)
public String startAuction(@PathVariable(value = "idauction") int idauction, RedirectAttributes redirect) {
AuctionItem addAuction = (AuctionItem) aucRepository.findOne(idauction);
List<Image> imageList = (List<Image>) imageRepository.findByidauction(idauction);
addAuction.setMainImage(imageList.get(0).getImagepath());
addAuction.setActive(true);
aucRepository.save(addAuction);
return "listing";
}
链接似乎工作正常，idauction在Web浏览器中填充，它似乎似乎没有映射到控制器。
这是完整的html输出：

您已经在/start控制器方法的confirmAuction后缀，您需要将其从JSP href中删除，如下所示：
<a href="/aucConfirm/${newAuction.idauction}" >Start Auction</a>

它最终非常简单，在路径的开头添加了两个点，现在它正确指向。无论如何，感谢所有的回复。
<a href="../aucConfirm/${newAuction.idauction}/start" >Start Auction</a>
