标签简化Spring-MVC配置

新填入@RequestMapping标签

和@org.springframework.stereotype.Controller标签

这样做就是通过标签来简化之前，对HandlerMapping的配置。HandlerMapping的作用也就无非是，接收前端request，再找到指定controller。

package com.controller;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

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

@org.springframework.stereotype.Controller
@RequestMapping("/path01/path02")
public class HelloController implements Controller{

    @Override
    public ModelAndView handleRequest(HttpServletRequest arg0,
            HttpServletResponse arg1) throws Exception {
        System.out.println("处理hello.form请求");
        ModelAndView mv = new ModelAndView("hello");
        return mv;
    }
    
    @RequestMapping("/hello.form")
    public String execute() throws Exception{
        return "hello";
    }
    
}

这样配置后，路径就是 localhost/myspring(project's name)/path01/path02/hello.form
