Question

当我运行此Web应用程序时。我收到404错误。当我检查该网址时，它是http://localhost:9090/SpringMVC/而不是http://localhost:9090/SpringMVC/welcome。你能帮我解决这个问题。

HelloWorldController.java

package org.controller.com;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class HelloWorldController {

    @RequestMapping("/welcome")
    public ModelAndView helloworld(){
        ModelAndView model = new ModelAndView("HelloPage");
        model.addObject("msg", "Hello World");
        return model;
    }


}
