基于SSM的健身房管理系统
基于SSM的健身房管理系统
The project was made in 2020-05-05~2020-05-10
谨以此片博文记录下我的第一个Java小Demo
代码请见GitHub
项目展示
用户登录页
用户注册页
用户主页
用户购买健身卡(商城)页
管理员登录页
管理员主页
管理员添加用户页
管理员编辑用户页
细节1：常驻工具栏（内含搜索栏）
细节2：登录账号密码实时反馈（AJAX）
**细节3：翻页功能&可选每页显示条数 **
细节4：人性化的交互设计
项目环境
JDK: 1.8
IDE: IDEA 201903
DataBase: MySQL 8.0
Mybatis: 3.5.2
POM: Maven
Tomcat 9
Bootstrap 3
JQuery 2
lombok 插件
分页插件: PageHelper 5.1.11
涉及技术 MySQL数据库，Spring，JavaWeb及MyBatis，简单的前端知识
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

POJO Mapper Services的编写
POJO
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();
}
}
Admin
@Data
@NoArgsConstructor
@AllArgsConstructor
public class Admin {
private int id;
private String username;
private String password;
private String name;
private String telephone;
}
Mapper
编写DAO层的Mapper接口
- 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);
//login
User userLogin(User user);
//会员注册
int userRegister(User user);
}
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);
//login
Admin 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();
}
编写接口对应的 Mapper.xml 文件
- 1 userMapper.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <mapper namespace="com.cc.dao.UserMapper">

</select>
<!--更新User-->

</update>
<!--根据账号密码查询,返回一个User-->
<select id="userLogin" resultType="User">

</select>
<!-- 会员注册-->
<!--增加一个会员-->

values (#{username},#{password},#{name},#{sex},#{telephone},#{age},#{begintime},#{endtime},#{remainday})
</insert>
</mapper>
- 2 adminMapper.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">

where username = #{username} and password = #{password}
</select>
<select id="selectTotal" resultType="int">
select count(*) from gymms.user
</select>
</mapper>
编写Service层的接口和实现类
- 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);
//login
User userLogin(User user);

}
- 2 adminService
public interface AdminService {

// 分页
List<User> findAll(); /**

* @return 返回PageHelper提供的封装分页参数的PageInfo对象

PageInfo<User> findByPage(int pageNum, int pageSize);
}

拓展与展望
以下功能在以后可拓展开发
结束与总结
这个小Demo做了五六天,分页那里卡了接近两天，无数的坑等着踩。
期间也体会到了编程的乐趣，每天晚上都肝的快快乐乐。
所有代码放在GitHub供大家交流学习。
今天母亲节呀，祝我妈妈母亲节快乐！ 晚安！
