1. [代码]控制器片段
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 | package com.wg.test; import javax.servlet.http.HttpServletRequest; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.servlet.ModelAndView; import com.wg.bean.User; import com.wg.service.UserService; @Controller public class UserController { @Autowired private UserService userService; @RequestMapping(value = "regist", method = RequestMethod.POST) public ModelAndView regist(HttpServletRequest request, User user) { try { userService.saveUser(user); } catch (Exception e) { e.printStackTrace(); } request.setAttribute("username", user.getUsername()); request.setAttribute("password", user.getPassword()); System.out.println(user.toString()); return new ModelAndView("succ"); } /*** * 用户登陆 * * 注解配置，只允许POST提交到该方法 * * @param username * @param password * @return */ @RequestMapping(value = "login", method = RequestMethod.POST) public ModelAndView login(String username, String password) { // 验证传递过来的参数是否正确，否则返回到登陆页面。 if (this.checkParams(new String[] { username, password })) { // 指定要返回的页面为succ.jsp ModelAndView mav = new ModelAndView("succ"); // 将参数返回给页面 mav.addObject("username", username); mav.addObject("password", password); System.out .println("username=" + username + " password=" + password); return mav; } return new ModelAndView("home"); } /*** * 验证参数是否为空 * * @param params * @return */ private boolean checkParams(String[] params) { for (String param : params) { if (param == "" || param == null || param.isEmpty()) { return false; } } return true; } } |
2. [代码]web.xml配置
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 | xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"> org.springframework.web.context.ContextLoaderListener /WEB-INF/classes/mvc-context.xml |
3. [代码]spring-mvc配置
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 | xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> class="org.springframework.web.servlet.view.UrlBasedViewResolver"> value="org.springframework.web.servlet.view.JstlView" /> |
4. [代码]userMapper配置
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 | "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> select id, username, password From user username =#{username} and password =#{password} and id=#{id} insert into user(id,username,password) values(#{id},#{username},#{password}) select last_insert_id() as id update user where id=#{id} delete from user where id=#{id} |
