Swing图形界面程序—同学通讯录系统(1)
一个简单的Swing程序（通讯录）
来东软一个月了，前天学了一个上午的Swing，老师要求做一个通讯录图形界面程序，就试着做了做，还有许多不完善的地方，如果有时间的话，后面还会接着改的，开发工具是MyEclipse,数据库使用的是Oracle数据库。首先把界面都摆出来吧！
登录界面
1.用户界面
2.用户添加自己同学信息
3.查询自己的同学信息
4.删除同学信息
5.修改个人密码
管理员界面
1.管理员添加用户
2.删除用户（非管理员用户）
接下来是数据库表的设计，就两张表，一个用户表，一个学生表
--用户信息表
create table user_info(
userid number primary key, --用户编号
username varchar(10 char) not null, --用户姓名
passwd varchar(32 char) not null, --用户密码
priv varchar(10) default 'common' not null check (priv in('common','director')), --用户权限 --1.admin 2.普通用户
registertime date default sysdate not null,
intime date default sysdate not null,
outitme date default sysdate not null
);
create table u_student
(
sno number primary key,
sname varchar(10 char) not null,
sex char(2) default '男' not null check (sex in('男','女')),
birthday date,
classno varchar(8 char) not null,
tel varchar(20 char) ,
email varchar(20 char),
address varchar(40 char),
userid number not null,
foreign key (userid) references user_info(userid)
);
这里就只要注意一下学生表的userid和用户的userid之间的关系，在用户删除那里要同时删除两张表中的数据，使用的是存储过程。
----存取过程----用来删除两张表中的数据---
create or replace procedure pro_s_u_userid(in_userid number) is
begin
delete from u_student where userid = in_userid;
delete from user_info where userid = in_userid;
end;
call pro_s_u_userid(1040);对学生表的操作类：StudentService.class
