二、搭建MyBatis逆向工程

简介：根据表生成mapper层三部分代码：实体类，mapper接口，映射文件。

1.创建meacen项目

2.修改pom.xml

  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <project xmlns="http://maven.apache.org/POM/4.0.0"
  3.          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  4.          xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  5.     <modelVersion>4.0.0</modelVersion>
  7.     <groupId>com.bjpowernode.crm</groupId>
  8.     <artifactId>crm-mybatis-generator</artifactId>
  9.     <version>1.0-SNAPSHOT</version>
  11.     <build>
  12.             <plugins>
  13.                 <!--myBatis逆向工程插件-->
  14.                 <plugin>
  15.                     <groupId>org.mybatis.generator</groupId>
  16.                     <artifactId>mybatis-generator-maven-plugin</artifactId>
  17.                     <version>1.3.2</version>
  18.                     <configuration>
  19.                         <verbose>true</verbose>
  20.                         <overwrite>true</overwrite>
  21.                     </configuration>
  22.                 </plugin>
  24.             </plugins>
  25.     </build>
  27. </project>

3.添加相关的配置文件

image.png
jdbc.driverLocation是mysql连接数据库jar包的位置

  1. jdbc.driverLocation=E:/Program/Project/Projectjava/reposity/mysql/mysql-connector-java/5.1.32/mysql-connector-java-5.1.32.jar
  2. jdbc.driverClass=com.mysql.jdbc.Driver
  3. jdbc.connectionURL=jdbc:mysql://127.0.0.1:3307/crm2008?useUnicode=true&characterEncoding=UTF-8
  4. jdbc.userId=root
  5. jdbc.password=123456

targetPackage：代码保存的目录
table：表的信息 需要哪一个表就打开那个

  179.         </context>
  180.         </generatorConfiguration>

三、实现Mapper层和Service层

image.png

Mapper

  1. /**
  2. * 根据账号和密码查询用户
  3. */
  4. User selectUserByLoginActAndPwd(Map<String,Object> map);
  1. <select id="selectUserByLoginActAndPwd" parameterType="map" resultMap="BaseResultMap">
  2.   select<include refid="Base_Column_List"></include>
  3.   from tbl_user
  4.   where login_act=#{loginAct} and login_pwd=#{loginPwd}
  5. </select>
  1. <!--注册mapper.xml文件-->
  2.     <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
  3.         <property name="basePackage" value="com.bjpowernode.crm.settings.mapper"></property>
  4.     </bean>

解释

  2. //@Service  //交给Spring去创建对象
  4. //public class UsersServiceImpl implements UsersService {
  5.     //切记切记:在所有的业务逻辑层中一定会有数据访问层的对象
  6.     /**
  7.      *         //1.读取核心配置文件
  8.      *         InputStream in = Resources.getResourceAsStream("SqlMapConfig.xml");
  9.      *         //2.创建工厂对象
  10.      *         SqlSessionFactory factory = new SqlSessionFactoryBuilder().build(in);
  11.      *         //3.取出sqlSession
  12.      *         sqlSession = factory.openSession(true);//自动提交事务
  13.      *         //4.取出动态代理的对象,完成接口中方法的调用,实则是调用xml文件中相的标签的功能
  14.      *         usersMapper = sqlSession.getMapper(UsersMapper.class);
  15.      */
  16.     //在以前我们通过上面的获取usersmapper，我们需要的是数据访问层的功能
  17.     //现在我们通过注解，spring帮我们完成注入
  19.     /*
  20.     MapperScannerConfigurer类已经完成了动态代理的实现
  21.      <!--注册mapper.xml文件-->
  22.   <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
  23.     <property name="basePackage" value="com.bjpowernode.mapper"></property>
  24.   </bean>
  25.     */
  26. /*
  27.     @Autowired
  28.     UsersMapper usersMapper;
  31.     @Override
  32.     public int insert(Users users) {
  33.         int num = usersMapper.insert(users);
  35.     }
  36. }
  37. */

别忘了改这个地方

  1.  <!--注册实体类-->
  2.         <property name="typeAliasesPackage" value="com/bjpowernode/crm/settings/domain"></property>

Service

image.png

  1. public interface UserService {
  2.     User selectUserByLoginActAndPwd(Map<String,Object> map);
  3. }
  1. @Service("userService")
  2. public class UserServiceImpl  implements UserService {
  4.     @Autowired
  5.     private UserMapper userMapper;
  7.     @Override
  8.     public User selectUserByLoginActAndPwd(Map<String, Object> map) {
  9.        return userMapper.selectUserByLoginActAndPwd(map);
  10.     }
  11. }
  1. <!--添加包扫描-->
  2. <context:component-scan base-package="com.bjpowernode.crm.settings.service"></context:component-scan>

四、完成Controller层

image.png

1.搭建逻辑框架UserController

  2. @Controller
  3.     public class UserController {
  5.         @Autowired  
  6.         private UserService userService;
  7.         @RequestMapping("/settings/qx/user/toLogin.do")
  8.         public String toLogin(){
  9.             //请求转发到登录页面
  10.             return "settings/qx/user/login";
  11.         }
  13.         @RequestMapping("/settings/qx/user/login.do")
  14.         @ResponseBody
  15.         public Object login(String loginAct, String loginPwd, String isRemPwd, HttpServletRequest request){
  16.             //封装参数
  17.             Map<String,Object> map=new HashMap<>();
  18.             map.put("loginAct",loginAct);
  19.             map.put("loginPwd",loginPwd);
  20.             //调用service层方法，查询用户
  21.             User user=userService.selectUserByLoginActAndPwd(map);
  23.             //根据查询结果，生成响应信息
  25.             if(user==null){
  26.                 //登录失败,用户名或者密码错误
  28.             }else{//进一步判断账号是否合法
  29.                 //user.getExpireTime()   //2019-10-20
  30.                 //        new Date()     //2020-09-10
  31.                 SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
  32.                 String nowStr=sdf.format(new Date());
  33.                 if(nowStr.compareTo(user.getExpireTime())>0){
  34.                     //登录失败，账号已过期
  36.                 }else if("0".equals(user.getLockState())){
  37.                     //登录失败，状态被锁定
  39.                 }else if(!user.getAllowIps().contains(request.getRemoteAddr())){
  40.                     //登录失败，ip受限
  42.                 }else{
  43.                     //登录成功
  45.                 }
  46.             }
  49.         }
  51.     }

2.添加实体类

image.png

  1. package com.bjpowernode.crm.commons.domain;
  3. public class ReturnObject {
  4.     private  String code;  //处理成功或者失败的标记  1 成功  0失败
  5.     private  String message;//提示信息
  6.     private  Object returnData; //其他数据
  8.     public String getCode() {
  9.         return code;
  10.     }
  12.     public void setCode(String code) {
  13.         this.code = code;
  14.     }
  16.     public String getMessage() {
  17.         return message;
  18.     }
  20.     public void setMessage(String message) {
  21.         this.message = message;
  22.     }
  24.     public Object getReturnData() {
  25.         return returnData;
  26.     }
  28.     public void setReturnData(Object returnData) {
  29.         this.returnData = returnData;
  30.     }
  31. }

3.完善UserController

  1. @Controller
  2. public class UserController {
  4.     @Autowired
  5.     private UserService userService;
  6.     @RequestMapping("/settings/qx/user/toLogin.do")
  7.     public String toLogin(){
  8.         //请求转发到登录页面
  9.         return "settings/qx/user/login";
  10.     }
  12.     @RequestMapping("/settings/qx/user/login.do")
  13.     @ResponseBody
  14.     public Object login(String loginAct, String loginPwd, String isRemPwd, HttpServletRequest request){
  15.         //封装参数
  16.         Map<String,Object> map=new HashMap<>();
  17.         map.put("loginAct",loginAct);
  18.         map.put("loginPwd",loginPwd);
  19.         //调用service层方法，查询用户
  20.         User user=userService.selectUserByLoginActAndPwd(map);
  22.         //根据查询结果，生成响应信息
  23.         ReturnObject returnObject  =new ReturnObject();
  24.         if(user==null){
  25.             //登录失败,用户名或者密码错误
  26.             returnObject.setCode("0");
  27.             returnObject.setMessage("用户名或者密码错误");
  28.         }else{//进一步判断账号是否合法
  29.             //user.getExpireTime()   //2019-10-20
  30.             //        new Date()     //2020-09-10
  31.             SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
  32.             String nowStr=sdf.format(new Date());
  33.             if(nowStr.compareTo(user.getExpireTime())>0){
  34.                 //登录失败，账号已过期
  35.                 returnObject.setCode("0");
  36.                 returnObject.setMessage("账号已过期");
  38.             }else if("0".equals(user.getLockState())){
  39.                 //登录失败，状态被锁定
  40.                 returnObject.setCode("0");
  41.                 returnObject.setMessage("状态被锁定");
  42.             }else if(!user.getAllowIps().contains(request.getRemoteAddr())){
  43.                 //登录失败，ip受限
  44.                 returnObject.setCode("0");
  45.                 returnObject.setMessage("ip受限");

  49.             }
  50.         }
  51.         return  returnObject;
  54.     }
  56.     }

4.优化UserController

  1. public class DateUtils {
  2.     //对指定的date对象进行格式化 yyyy-MM-dd HH:mm:ss"
  3.     public static String formateDateTime(Date date){

  20.     }
  21. }
  1. public class Contants {

  28.         }
  29.         return  returnObject;
  32.     }

5.修改前端页面

6.登录之后显示业务与主页面名称

先把这个复制过去然后再改成jsp

五、完善功能

1.登录成功之后,所有业务页面显示当前用户的名称

回顾知识点:

pageContext:同一页面不同标签之间传递数据。 request:在同一个请求过程中传递数据。 sesson:在同一个浏览器窗口的不同请求之间传递数据。 application:所有用户共享的数据，并且是频繁使用的

我们把”sessionUser”设置为一个常量，将来改的时候只需要改这个就行

  1. public class Contants {
  2.     //保存ReturnObject类中的Code值
  3.     public static final String RETURN_OBJECT_CODE_SUCCESS="1";//成功的
  4.     public static final String RETURN_OBJECT_CODE_FAIL="0";//失败的
  6.     //保存当前用户的key
  7.     public static final String SESSION_USER="sessionUser";
  8. }
  1.     public Object login(String loginAct, String loginPwd, String isRemPwd, HttpServletRequest request, HttpSession session){
  2.         //封装参数
  3.         Map<String,Object> map=new HashMap<>();
  4.         map.put("loginAct",loginAct);
  5.         map.put("loginPwd",loginPwd);
  6.         //调用service层方法，查询用户
  7.         User user=userService.selectUserByLoginActAndPwd(map);
  9.         //根据查询结果，生成响应信息
  10.         ReturnObject returnObject  =new ReturnObject();
  11.         if(user==null){
  12.             //登录失败,用户名或者密码错误
  13.             returnObject.setCode(Contants.RETURN_OBJECT_CODE_FAIL);
  14.             returnObject.setMessage("用户名或者密码错误");
  15.         }else{//进一步判断账号是否合法
  16.             //user.getExpireTime()   //2019-10-20
  17.             //        new Date()     //2020-09-10
  19.             String nowStr= DateUtils.formateDateTime(new Date());
  20.             if(nowStr.compareTo(user.getExpireTime())>0){
  21.                 //登录失败，账号已过期
  22.                 returnObject.setCode(Contants.RETURN_OBJECT_CODE_FAIL);
  23.                 returnObject.setMessage("账号已过期");
  25.             }else if("0".equals(user.getLockState())){
  26.                 //登录失败，状态被锁定
  27.                 returnObject.setCode(Contants.RETURN_OBJECT_CODE_FAIL);
  28.                 returnObject.setMessage("状态被锁定");
  29.             }else if(!user.getAllowIps().contains(request.getRemoteAddr())){
  30.                 //登录失败，ip受限
  31.                 returnObject.setCode(Contants.RETURN_OBJECT_CODE_FAIL);
  32.                 returnObject.setMessage("ip受限");
  33.             }else{
  34.                 //登录成功
  35.                 returnObject.setCode(Contants.RETURN_OBJECT_CODE_SUCCESS);
  36.                 //把User保存到session中
  37.                 session.setAttribute(Contants.SESSION_USER,user);
  38.             }

2.实现回车登录

知识点:jquery事件函数的用法

  1.  1.**选择器.click(function(){    //给指定的元素添加事件**

//js代码 });

2.选择器.click();//在指定的元素上模拟发生的一次事件

  1. //...............
  2. $(function () {
  3.   //给整个浏览器窗口添加键盘按下事件
  4.   $(window).keydown(function (e){
  5.     //如果按下的是回车键，则提交登录请求
  6.     if(e.keyCode==13){
  7.       $("#loginBtn").click();
  8.     }
  9.   });
  11.   //给"登录"按钮添加单击事件
  12.   $("#loginBtn").click(function () {
  13.     //收集参数
  14.     var loginAct=$.trim($("#loginAct").val());
  15.     var loginPwd=$.trim($("#loginPwd").val());
  16.     var isRemPwd=$("#isRemPwd").prop("checked");
  17.     //表单验证
  18.     if(loginAct==""){
  19.       alert("用户名不能为空");
  20.       return;
  21.     }
  22.     if(loginPwd==""){
  23.       alert("密码不能为空");
  24.       return;
  25.     }
  26.     //............

3.实现记住密码十天内免登录

如果上次记住密码，自动填上账户和密码，否则，不填。
如何判断上次记住密码?
—上次登录成功，判断是否需要记住密码:如果需要记住密码，则往浏览器写cookie;否则.删除cookie。
而且cookie的值必须是该用户的loginAct和loginPwd。
—下次登录时,判断该用户有没有cookie,如果有则自动填写账号和密码，如果没有则不写。
而且填写的是cookie的值。

  1. returnObject.setMessage("ip受限");
  2. }else{
  3.     //登录成功
  4.     returnObject.setCode(Contants.RETURN_OBJECT_CODE_SUCCESS);
  5.     //把User保存到session中
  6.     session.setAttribute(Contants.SESSION_USER,user);
  8.     //如果需要记住密码，则写cookie
  9.     if("true".equals(isRemPwd)){
  10.         Cookie c1 =new Cookie("loginAct",user.getLoginAct());
  11.         c1.setMaxAge(10*24*60*60);
  12.         response.addCookie(c1);
  13.         Cookie c2= new Cookie("loginPwd",user.getLoginPwd());
  14.         c2.setMaxAge(10*24*60*60);
  15.         response.addCookie(c2);
  16.     }else{
  17.         //把没有过期的cookie删除
  18.         Cookie c1=  new Cookie("loginAct","1");
  19.         c1.setMaxAge(0);
  20.         response.addCookie(c1);
  21.         Cookie c2=  new Cookie("loginPwd","1");
  22.         c2.setMaxAge(0);
  23.         response.addCookie(c2);
  24.     }
  25. }
