Redirects the request to forward the login form

Specific description of the problem

1. Redirected to the page can not be accessed under the WEB-INF
2. After you submit the login form into the WEB-INF use when the request is forwarded
3. After the request is forwarded to refresh the page will re-submit the form
4. So that even after the return of the Log will log in directly refresh the page again

Solution

Redirect to a method of forwarding the request

• The original method

    @RequestMapping("/login")
    public String login(){
        return ("admin/index");//请求转发到登陆后的主页
    }

• ways to improve

    @RequestMapping("/login")
    public String login(){
        return ("redirect:/system/toLogin");//重定向toLogin链接
    }
  
    @RequestMapping("/toLogin")
    public String toLogin(){
        return ("admin/index");//请求转发到登陆后的主页
    }
