javaweb 简单的同学聚会系统

今年大三了，很多3年制的同学都要毕业出去工作了，来年我也要出去实习。本着在工作之前办一个不变味的同学聚会的目的，写了这个么一简陋的聚会信息收集系统。前前后后花的时间也不多，用到了springmvc 和 mybatis 的技术（只能说技术，不能说整合）。

总的目录结构：



导入的包：（我把常用的都导进去了，肯定有些用不上的 ）



数据库：

create database gather;
use gather;
create table wuni(
id int primary key auto_increment,
name varchar(20),
phone varchar(20),
weichat varchar(20),
qq varchar(20)
);
create table daya(
id int primary key auto_increment,
name varchar(20),
phone varchar(20),
weichat varchar(20),
qq varchar(20)
);

javabean: User.java

package com.loger.bean;

public class User {
private int id;
private String name;
private String phone;
private String weichat;
private String qq;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPhone() {
return phone;
}
public void setPhone(String phone) {
this.phone = phone;
}
public String getWeichat() {
return weichat;
}
public void setWeichat(String weichat) {
this.weichat = weichat;
}
public String getQq() {
return qq;
}
public void setQq(String qq) {
this.qq = qq;
}

@Override
public String toString() {
return "User [id=" + id + ", name=" + name + ", phone=" + phone + ", weichat=" + weichat + ", qq=" + qq + "]";
}
public User(int id, String name, String phone, String weichat, String qq) {
super();
this.id = id;
this.name = name;
this.phone = phone;
this.weichat = weichat;
this.qq = qq;
}
public User() {
super();
}

}

对数据库的各种操作：Insert.java （这里名字就这么取了）

（我这里对两个班级的聚会信息收集本来是合在一起写的，但是测试的时候发现两个插入都是插到同一个班级里，索性就分开来写了，分开来还是不行，最后发现是sql语句写错了，懒得合在一起了，包括后面的收集页面也是因为这个原因写了两个。这里有很多代码功能是重复的，也懒得去管了！）

css 和 js 部分省略
