You don't need the /in the method's mapping. Just map it to "".
您不需要/方法的映射中的 。只需将其映射到"".

Yes that is possible. The path in @RequestMappingon the method is relative to the path on the class annotation.
是的，这是可能的。在路径@RequestMapping上的方法是相对于在类注释的路径。
With your current setup, loginRoot()will handle requests to
使用您当前的设置，loginRoot()将处理请求
localhost:8080/projectname/login/
Assuming you don't have anything else in your configuration preventing this.
假设您的配置中没有其他任何内容可以防止这种情况发生。

You don't need to "/" and you need to also add the request method.
您不需要“/”，您还需要添加请求方法。
@RequestMapping(method = RequestMethod.GET)
public String loginRoot() {
return "login";
}
