嗨,我已经创建了一个 Spring MVC 应用程序,我有一个名为 Estimation 的控制器,有两种方法。
我可以通过访问这个网址www.wesite.com/xyz/estimation来访问这个控制器的home 方法
但我尝试通过访问此网址www.wesite.com/xyz/estimation/1来访问homeById方法,但 出现 404 错误,请求的资源不可用。
任何机构都可以对此有所了解。
@Controller
@RequestMapping("/estimation")
public class EstimationController {
@RequestMapping("")
public ModelAndView home(HttpServletRequest request, HttpServletResponse response) {
ModelAndView mv = new ModelAndView("productEstimate");
return mv;
}
@RequestMapping(value="/{productId}", method = RequestMethod.GET)
public ModelAndView homeById(HttpServletRequest request, HttpServletResponse response,@PathVariable int productId) {
ModelAndView mv = new ModelAndView("productEstimate");
return mv;
}
