Controler:

package com.mkyong.controller;

import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

@Controller

public class BaseController {

    @RequestMapping(value = "/welcome", method = RequestMethod.GET)
    public String welcome(ModelMap model) {
        System.out.println("am here");

        model.addAttribute("message",
                "Maven Web Project + Spring 3 MVC - welcome()");

        // Spring uses InternalResourceViewResolver and return back index.jsp
        return "index";

    }

    @RequestMapping(value = "/welcome/{name}", method = RequestMethod.GET)
    public String welcomeName(@PathVariable String name, ModelMap model) {

        model.addAttribute("message", "Maven Web Project + Spring 3 MVC - "
                + name);
        return "index";

    }

}

当我直接登录ro welcome.html时，从重新直接页面收到以下错误

HTTP状态404 - / Spring-security / welcome

输入状态报告

消息/ Spring-security / welcome

说明请求的资源不可用。
