校园活动管理系统
一、题目
校园社团活动管理系统(20分)
1、项目需求:
校园社团作为高校课外活动的重要组成部分,发展十分迅速,也受到越来越多学生的欢迎,社团规模、数量等都在日益增长,社团活动也更为多样和丰富。然而,大多数高校还没有一个完整成熟的社团管理系统,仅仅是靠人力来管理,导致效率低下,而学生也只能通过线下或者公众号的方式了解社团,另外,社团活动的通知方式也很杂乱,并没有一个信息聚合、消息发布的平台。
因此,高校有必要建立一个校园社团管理系统,使得社团管理工作规范化、系统化、程序化、科学化,提高管理工作的效率。
2.系统要求与功能设计

二、思路
三、代码
使用mybatis+Mapper代理来实现功能
使用到的jar包:mybatis、jQuery(进行js校验)、mysql
1.mysql.properties(配置文件)
driver=com.mysql.cj.jdbc.Driver url=jdbc:mysql://127.0.0.1:3306/course?serverTimezone=UTC&useSSL=false&characterEncoding=UTF-8 username=root password=123456
2.mybatis-config.xml(配置文件)
<?xml version="1.0" encoding="utf-8" ?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration> <properties resource="mysql.properties"/> <!-- 对事物的管理和连接池的配置 --> <environments default="development"> <environment id="development"> <transactionManager type="JDBC"/> <!--连接池信息--> <dataSource type="POOLED"> <property name="driver" value="${driver}"/> <property name="url" value="${url}"/> <property name="username" value="${username}"/> <property name="password" value="${password}"/> </dataSource> </environment> </environments> <!--mappers映射器--> <mappers> <!--映射文件方式2.自动扫描包内的Mapper接口和配置文件--> <package name="com.xxxx.mapper"/> </mappers> </configuration>
3.HuodongMapper.java (Mapper接口类)
package com.xxxx.mapper; import com.xxxx.entity.Huodong; import org.apache.ibatis.annotations.Param; import java.util.List; public interface HuodongMapper { void add(Huodong huodong); List<Huodong> selectBylessThanId(int id); Huodong selectByZhuti(String zhuti); void update(@Param("huodong") Huodong huodong,@Param("id") int id); void deleteById(int id); List<Huodong> selectAll(); Huodong chaxunBytiaojian(@Param("zhuti") String zhuti,@Param("time") String time,@Param("type") String type,@Param("place") String place); }
4.HuodongMapper.xml(Mapper.xml配置文件)
