实现Controller 接口，将handleRequest函数改造成分发器

【PersonController】

package com.action;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.springframework.web.servlet.ModelAndView;import org.springframework.web.servlet.mvc.Controller;import com.dao.PersonDao;import com.entity.Person;public class PersonController implements Controller {    private PersonDao dao;    public void setDao(PersonDao dao) {        this.dao = dao;    }    <!-- 分发器 -->    public ModelAndView handleRequest(HttpServletRequest arg0,            HttpServletResponse arg1) throws Exception {        String url = arg0.getRequestURI();        String m = url.substring(url.lastIndexOf("/") + 1);        if (m.equals("login.do")) {            return this.login(arg0, arg1);        } else if (m.equals("register.do")) {            return this.register(arg0, arg1);        } else {            return null;        }    }    public ModelAndView login(HttpServletRequest arg0, HttpServletResponse arg1)            throws Exception {        String uname = arg0.getParameter("uname");        String pwd = arg0.getParameter("pwd");        ModelAndView m = new ModelAndView();        boolean b = dao.login(uname, pwd);        if (b) {            m.addObject("message", "登录成功");        }        m.setViewName("/ok.jsp");        return m;    }    public ModelAndView register(HttpServletRequest arg0, HttpServletResponse arg1)            throws Exception {        String id = arg0.getParameter("id");        String pname = arg0.getParameter("pname");        String pwd = arg0.getParameter("pwd");        ModelAndView m = new ModelAndView();        Person p = new Person();        p.setId(Integer.valueOf(id));        p.setPname(pname);        p.setPwd(pwd);        dao.add(p);        m.addObject("message","注册ok");        m.setViewName("/ok.jsp");        return m;    }}

【applicationContext.xm】
