本文详细介绍了 Spring MVC 中的 URL 映射机制，包括如何通过注解配置不同的请求映射规则，如前缀匹配、后缀匹配、绝对路径匹配及任意层级路径匹配等，并展示了如何使用这些规则实现具体的业务功能。

package cn.wycclub.handlers;

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.stereotype.Controller;

@Controller
@RequestMapping("/test")
public class MyController {

       @RequestMapping("/third*.do")  //资源名称必须以third开头
	public ModelAndView doThird(HttpServletRequest arg0, HttpServletResponse arg1) throws Exception {
		ModelAndView mv = new ModelAndView();
		mv.addObject("message","doThird");
		mv.setViewName("/WEB-INF/jsp/welcome.jsp");
		return mv;
	}
	
	@RequestMapping("/*fourth.do")//资源名称必须以fourth结尾
	public ModelAndView doFourth(HttpServletRequest arg0, HttpServletResponse arg1) throws Exception {
		ModelAndView mv = new ModelAndView();
		mv.addObject("message","doFourth");
		mv.setViewName("/WEB-INF/jsp/welcome.jsp");
		return mv;
	}
	
	@RequestMapping("/*/fifth.do") //路径级数的绝对匹配，既要求在test与fifth.do之间必须有一级路径
	public ModelAndView doFifth(HttpServletRequest arg0, HttpServletResponse arg1) throws Exception {
		ModelAndView mv = new ModelAndView();
		mv.addObject("message","doFifth");
		mv.setViewName("/WEB-INF/jsp/welcome.jsp");
		return mv;
	}
	
	@RequestMapping("/**/sixth.do") //要求在test与sixth.do之间可以包含零到多级路径
	public ModelAndView doSixth(HttpServletRequest arg0, HttpServletResponse arg1) throws Exception {
		ModelAndView mv = new ModelAndView();
		mv.addObject("message","doSixth");
		mv.setViewName("/WEB-INF/jsp/welcome.jsp");
		return mv;
	}
