项目详情

设计数据库

大二没有好好学系统设计与分析，画的图一塌糊涂。

包含两个实体类，用户&管理员

生成该数据库的sql文件 在该GitHub跳转GitHub /sql 目录下

生成表如图示

设计要实现的功能

应该叫做用例图吧，但我的好多符号都是错的，再次后悔没有好好学习！

制作前端页面Demo

设计该图的webProcessOn

其实这一步放在后面也合适，我为了让自己吃大饼，就先设计了一下。

环境配置

项目文件结构如图所示

基本步骤

1. 新建Maven项目，添加web支持

2. 导入pom依赖

   <dependencies><!--Junit--><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.12</version></dependency><!--数据库驱动--><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>5.1.47</version></dependency><!-- 数据库连接池 --><dependency><groupId>com.mchange</groupId><artifactId>c3p0</artifactId><version>0.9.5.2</version></dependency><!--Servlet - JSP --><dependency><groupId>javax.servlet</groupId><artifactId>servlet-api</artifactId><version>2.5</version></dependency><dependency><groupId>javax.servlet.jsp</groupId><artifactId>jsp-api</artifactId><version>2.2</version></dependency><dependency><groupId>javax.servlet</groupId><artifactId>jstl</artifactId><version>1.2</version></dependency><!--Mybatis--><dependency><groupId>org.mybatis</groupId><artifactId>mybatis</artifactId><version>3.5.2</version></dependency><dependency><groupId>org.mybatis</groupId><artifactId>mybatis-spring</artifactId><version>2.0.2</version></dependency><!--Spring--><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>5.1.9.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-jdbc</artifactId><version>5.1.9.RELEASE</version></dependency>
   </dependencies>
   

3. Maven资源过滤

   <build><resources><resource><directory>src/main/java</directory><includes><include>**/*.properties</include><include>**/*.xml</include></includes><filtering>false</filtering></resource><resource><directory>src/main/resources</directory><includes><include>**/*.properties</include><include>**/*.xml</include></includes><filtering>false</filtering></resource></resources>
   </build>
   

4. 建立基本结构框架 如上所示[点此跳转](# 环境配置)

5. 建立基本配置

   • mybatis-config.xml

     <?xml version="1.0" encoding="UTF-8" ?>
     <!DOCTYPE configurationPUBLIC "-//mybatis.org//DTD Config 3.0//EN""http://mybatis.org/dtd/mybatis-3-config.dtd">
     <configuration></configuration>
     

   • applicationContext.xml

     <?xml version="1.0" encoding="UTF-8"?>
     <beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsd"></beans>
     

6. Mybatis层编写

   • 数据库配置文件 database.properties

     jdbc.driver=com.mysql.jdbc.Driver
     jdbc.url=jdbc:mysql://localhost:3306/ssmbuild?useSSL=true&useUnicode=true&characterEncoding=utf8
     jdbc.username=root
     jdbc.password=123456IDEA关联数据库
     

   • IDEA关联数据库

   • 编写MyBatis的核心配置文件

     <?xml version="1.0" encoding="UTF-8" ?>
     <!DOCTYPE configurationPUBLIC "-//mybatis.org//DTD Config 3.0//EN""http://mybatis.org/dtd/mybatis-3-config.dtd">
     <configuration><typeAliases><package name="com.kuang.pojo"/></typeAliases><mappers><mapper resource="com/kuang/dao/BookMapper.xml"/></mappers></configuration>
     

POJO Mapper Services的编写

POJO

1. User

   @Data  //使用lombok插件即可省写get set
   @AllArgsConstructor
   @NoArgsConstructor
   public class User {private int id;private String username;private String password;private String name;private String sex;private String telephone;private int age;private String begintime;private String endtime;private int remainday;private int addday;public static void main(String[] args) {User u = new User();u.getTelephone();}
   }
   

2. Admin

   @Data
   @NoArgsConstructor
   @AllArgsConstructor
   public class Admin {private int id;private String username;private String password;private String name;private String telephone;
   }
   

Mapper

1. 编写DAO层的Mapper接口

   1. 1 userMapper

   public interface UserMapper {//通过id查询User queryUserById(int id);
   //    查询到期时间Date queryDateById(int id);//修改账号密码int updateNP(User user);//loginUser userLogin(User user);//会员注册int userRegister(User user);
   }
   

   1. 2 adminMapper

      @Mapper
      @Component
      public interface AdminMapper{//查询会员List<User> queryUser();//新增会员int addUser(User user);//删除会员int deleteUserById(int id);//更新会员int updateUser(User user);//根据id查询一个会员User queryUserById(int id);//根据姓名查询一个会员User queryUserByName(String name);//loginAdmin adminLogin(Admin admin);//查询用户总数int selectTotal();//    分页@Select("select * from gymms.user")@Results({// 用户信息，只要指定id列与属性的映射关系，其他列会自动封装（属性与列一致）@Result(property = "id", column = "id"),// 信息@Result(property = "id", column = "id"),@Result(property = "username", column = "username"),@Result(property = "password", column = "password"),@Result(property = "name", column = "name"),@Result(property = "sex", column = "sex"),@Result(property = "telephone", column = "telephone"),@Result(property = "age", column = "age"),@Result(property = "begintime", column = "begintime"),@Result(property = "endtime", column = "endtime"),@Result(property = "remainday", column = "remainday")})List<User> findAll();
      }
      

2. 编写接口对应的 Mapper.xml 文件

   1. 1 userMapper.xml

   <?xml version="1.0" encoding="UTF-8" ?>
   <!DOCTYPE mapperPUBLIC "-//mybatis.org//DTD Mapper 3.0//EN""http://mybatis.org/dtd/mybatis-3-mapper.dtd"><mapper namespace="com.cc.dao.UserMapper"><select id="queryDate" resultType="User">select remainday from gymms.userwhere id = #{id}</select>
   <!--    查询用户--><select id="queryUserById" resultType="User">select * from gymms.userwhere id = #{id}</select><!--更新User--><update id="updateUser" parameterType="User">update gymms.userset username = #{username},password = #{password}where id = #{id}</update><!--根据账号密码查询,返回一个User--><select id="userLogin" resultType="User">select * from gymms.userwhere username = #{username} and password = #{password}</select>
   <!--    会员注册--><!--增加一个会员--><insert id="userRegister" parameterType="User">insert into gymms.user(username,password,name,sex,telephone,age,begintime,endtime,remainday)values (#{username},#{password},#{name},#{sex},#{telephone},#{age},#{begintime},#{endtime},#{remainday})</insert>
   </mapper>
   

   1. 2 adminMapper.xml

   <?xml version="1.0" encoding="UTF-8" ?>
   <!DOCTYPE mapperPUBLIC "-//mybatis.org//DTD Mapper 3.0//EN""http://mybatis.org/dtd/mybatis-3-mapper.dtd">
   <mapper namespace="com.cc.dao.AdminMapper"><!--增加一个会员--><insert id="addUser" parameterType="User">insert into gymms.user(username,password,name,sex,telephone,age,begintime,endtime,remainday)values (#{username},#{password},#{name},#{sex},#{telephone},#{age},#{begintime},#{endtime},#{remainday})</insert><!--根据id删除一个User--><delete id="deleteUserById" parameterType="int">delete from gymms.user where id=#{id}</delete><!--更新User--><update id="updateUser" parameterType="User">update gymms.userset username = #{username},password = #{password},name = #{name},sex = #{sex},telephone = #{telephone},age = #{age},endtime = #{endtime},remainday = #{remainday}where id = #{id}</update><!--根据id查询,返回一个User--><select id="queryUserById" resultType="User">select * from gymms.userwhere id = #{id}</select><!--根据姓名查询,返回一个User--><select id="queryUserByName" resultType="User">select * from gymms.userwhere name = #{name}</select><!--查询全部Book--><select id="queryUser" resultType="User">SELECT * from gymms.user</select><!--根据账号密码查询,返回一个Admin--><select id="adminLogin" resultType="Admin">select * from gymms.adminwhere username = #{username} and password = #{password}</select><select id="selectTotal" resultType="int">select count(*) from gymms.user</select>
   </mapper>
   

3. 编写Service层的接口和实现类

   1. 1 userService

   public interface UserService {//    查询到期时间Date queryDateById(int id);//修改账号密码int updateNP(User user);//loginUser userLogin(User user);//通过id查询User queryUserById(int id);//会员注册int userRegister(User user);
   }
   

   1. 2 adminService

   public interface AdminService {//查询会员List<User> queryUser();//新增会员int addUser(User user);//删除会员int deleteUserById(int id);//更新会员int updateUser(User user);//根据id查询一个会员User queryUserById(int id);//根据姓名查询一个会员User queryUserByName(String name);//loginAdmin adminLogin(Admin admin);//查询用户总数int selectTotal();//    分页List<User> findAll();/*** 分页查询* @param pageNum  当然页* @param pageSize 页大小* @return 返回PageHelper提供的封装分页参数的PageInfo对象*/PageInfo<User> findByPage(int pageNum, int pageSize);
   }
   

   1. 3 userServiceImpl

   public class UserServiceImpl implements UserService {private UserMapper userMapper;public void setUserMapper(UserMapper userMapper) {this.userMapper = userMapper;}public Date queryDateById(int id) {return userMapper.queryDateById(id);}public int updateNP(User user) {return userMapper.updateNP(user);}public User userLogin(User user) {return userMapper.userLogin(user);}public User queryUserById(int id) {return userMapper.queryUserById(id);}public int userRegister(User user) {return userMapper.userRegister(user);}
   }
   

   1. 4 adminServiceImpl

   public class AdminServiceImpl implements AdminService {private AdminMapper adminMapper;public void setAdminMapper(AdminMapper adminMapper) {this.adminMapper = adminMapper;}public List<User> queryUser() {return adminMapper.queryUser();}public int addUser(User user) {return adminMapper.addUser(user);}public int deleteUserById(int id) {return adminMapper.deleteUserById(id);}public int updateUser(User user) {return adminMapper.updateUser(user);}public User queryUserById(int id) { return adminMapper.queryUserById(id); }public User queryUserByName(String name) { return adminMapper.queryUserByName(name); }public Admin adminLogin(Admin admin) {return adminMapper.adminLogin(admin);}public int selectTotal() {return adminMapper.selectTotal();}public List<User> findAll() {return adminMapper.findAll();}public PageInfo<User> findByPage(int pageNum, int pageSize) {PageHelper.startPage(pageNum, pageSize);List<User> list = adminMapper.findAll();PageInfo<User> pageInfo = new PageInfo<>(list);return pageInfo;}
   }
   

Spring层

• 配置Spring整合MyBatis，我们这里数据源使用c3p0连接池；

• 编写Spring整合Mybatis的相关的配置文件；
