firstcontroller.java

一个简单的基于spring的mvc实现

package controller;

import service.*;

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

import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;

public class FirstController implements Controller {
	
	private String errorPage = "";
	private String successPage = "";
	
	public ModelAndView handleRequest(HttpServletRequest request,
			HttpServletResponse response) throws Exception {
		// TODO Auto-generated method stub
		String username = request.getParameter("username");
		String psw = request.getParameter("psw");
		IUserService user =  UserServiceFactory.getUserService();
		if(user.isUser(username, psw)){
			return new ModelAndView(this.getSuccessPage(),"username",username);
		}else{
			return new ModelAndView(this.getErrorPage(),"username",username);
		}
	}

	public String getErrorPage() {
		return errorPage;
	}

	public void setErrorPage(String errorPage) {
		this.errorPage = errorPage;
	}

	public String getSuccessPage() {
		return successPage;
	}

	public void setSuccessPage(String successPage) {
		this.successPage = successPage;
	}

}
