Question

我想在tomcat上用MAVEN创建简单的Spring MVC应用程序。它有一个带有登录链接的主屏幕，点击该链接时应重定向到登录页面。为了实现这一点，我创建了一个登录控制器来返回login.html。在主页中单击登录时。我面临的问题是MVC控制器没有被触发。请帮忙!!

This is my folder structure: LoginController.java：

package com.bestbuy.tcs.mw.automation.controller;
@Controller
public class LoginController {
    //@Autowired
    //LoginService loginService;

    @RequestMapping("/login")
    public String showLogin(HttpServletRequest request, HttpServletResponse response){
        System.out.println("inside ");
        return "/login";
    }
}

首页网址 - 显示

https://localhost:8080/middlewareAutomation/

登录页面网址无效 - 抛出404，请求的资源不可用错误。

https://localhost:8080/middlewareAutomation/login

Answer 1

我认为第二个URL的正确版本应为

https://localhost:8080/middlewareAutomation/login.html

在mvc中没有为html视图调用Spring Controller
