SSM实现的用户登录

Spring MVC + Spring + MyBatis实现的用户登录模块,基于注解实现,简单好用

package com.sunline.action;

import javax.servlet.http.HttpSession;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.view.RedirectView;

import com.sunline.entity.User;
import com.sunline.service.UserService;

/*
 * 处理用户请求的控制器
 */

@Controller
public class UserController {
     //自动注入UserService
	@Autowired
	@Qualifier（“userService“）
	private UserService userService;
	
	/*
	 * 处理登录请求
	 */
	@RequestMapping（value=“/login“）
	public ModelAndView login（String user_nameString user_passwordModelAndView mvHttpSession session）{     //注意此处的字符名称必须和input的name一致
		//根据登录名和密码查找用户，判断用户登录
		User user = userService.Login（user_name user_password）;
		if（user!=null）{
			// 登录成功，将user对象设置到HttpSession作用范围域
			session.setAttribute（“user“ user）;
			//转发到main请求
			//mv.setView（new RedirectView（“/fkbookapp/main“））;
			mv.setViewName（“Main“）;
		}
		else{
			// 登录失败，设置失败提示信息，并跳转到登录页面
			mv.addobject（“message“ “登录名或密码错误，请重新输入!“）;
			mv.setViewName（“error“）;
		}
		return mv;
	}
}
