Spring MVC调度程序servlet，不带应用程序名称的URI

Question

I am trying to reach my controller:

package com.atmWebApp.controllers;

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

@Controller
public class FirstController {

        @RequestMapping("/welcome/")
        public ModelAndView helloWorld() {

            String message = "<br><div align='center'>" + "<h1>Hello World, Spring 3.2.1 Example by Crunchify.com<h1> <br>";
            message += "<a href='http://crunchify.com/category/java-web-development-tutorial/'>More Examples</a>";
            return new ModelAndView("welcome", "message", message);
        }

        @RequestMapping("/")
        public ModelAndView helloWorld1() {

            String message = "<br><div align='center'>" + "<h1>Hello World, Spring 3.2.1 Example by Crunchify.com<h1> <br>";
            message += "<a href='http://crunchify.com/category/java-web-development-tutorial/'>More Examples</a>";
            return new ModelAndView("welcome", "message", message);
        }
}

app-servlet.xml:

Specifically, I would like to start my server and have my root be at localhost:8080/, but I can't even seem to hit FirstController. So my main question is: why am I not hitting either method in FirstController?

I believe that my issue is in the app-server.xml or web.xml files. I have looked through stack overflow here , here , here , and here , but am at a loss as to what I am doing differently than these folks.

Any help?

Answer 1

From what I know you should have a @RequestMapping(..) on the Controller also. Hence you should have something like this:

@Controller
@RequestMapping("/")
public class FirstController {
    ...

As well you can check also this response for URL mappings.

Answer 2

在web.xml文件的servlet映射下，尝试将Url-Pattern从/更改为/ *。
