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) isbegin  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

package com.edu.services;import java.sql.Connection;import java.sql.PreparedStatement;import java.sql.ResultSet;import java.util.ArrayList;import java.util.List;import com.edu.db.DBUtils;public class StudentService {private Connection conn = null;private PreparedStatement pstm = null;private ResultSet rs = null;public boolean del(String sno,String userid) throws Exception{try{conn = DBUtils.getConnectiOn();String sql = "DELETE FROM U_STUDENT WHERE SNO = ? AND USERID = ?";pstm = conn.prepareStatement(sql);pstm.setString(1, sno);pstm.setString(2, userid);return pstm.executeUpdate() > 0;} finally{DBUtils.close(pstm);DBUtils.close(conn);}}/** * 通过sno查询 * @param sno * @return * @throws Exception */public List<String []> queryForDel(String sno,String userid) throws Exception{try{conn = DBUtils.getConnectiOn();StringBuilder sql = new StringBuilder().append("SELECT S.SNO,S.SNAME,S.SEX,S.BIRTHDAY,S.CLASSNO,").append("S.TEL,S.EMAIL,S.ADDRESS  FROM U_STUDENT S ").append(" WHERE USERID = ? ");if (sno != null && !sno.equals("")) {sql.append(" AND S.SNO = ? ");}sql.append(" ORDER BY S.SNAME");pstm = conn.prepareStatement(sql.toString());pstm.setString(1, userid);if (sno != null && !sno.equals("")) {pstm.setString(2, sno);}rs = pstm.executeQuery();List<String []> list = new ArrayList<String[]>();String val [] = null;int count = 0;while(rs.next()){val = new String [] {String.valueOf(++count),rs.getString(1),rs.getString(2),rs.getString(3),rs.getString(4),rs.getString(5),rs.getString(6),rs.getString(7),rs.getString(8)};list.add(val);}return list;} finally{DBUtils.close(rs);DBUtils.close(pstm);DBUtils.close(conn);}}/** * 模糊查询姓名 * @param username * @return * @throws Exception */public List<String []> query(String username,String userid) throws Exception{try{conn = DBUtils.getConnectiOn();StringBuilder sql = new StringBuilder().append("SELECT S.SNAME,S.SEX,TO_CHAR(S.BIRTHDAY,'YYYY-MM-DD'),S.CLASSNO,").append("       S.TEL,S.EMAIL,S.ADDRESS").append("  FROM U_STUDENT S").append(" WHERE USERID = ? ");if (username != null && !username.equals("")) {sql.append(" AND S.SNAME LIKE ?");}sql.append(" ORDER BY S.SNAME");pstm = conn.prepareStatement(sql.toString());pstm.setObject(1, userid);if (username != null && !username.equals("")) {pstm.setObject(2, "%" + username + "%");}//System.out.println("SQL : " + sql.toString());rs = pstm.executeQuery();List<String []> list = new ArrayList<String[]>();String val [] = null;int count = 0;while(rs.next()){val = new String []{String.valueOf(++count),rs.getString(1),rs.getString(2),rs.getString(3),rs.getString(4),rs.getString(5),rs.getString(6),rs.getString(7)};list.add(val);//System.out.println("list of service : " + list);}return list;} finally{DBUtils.close(rs);DBUtils.close(pstm);DBUtils.close(conn);}}/** * 添加 * @param val * @return * @throws Exception */public boolean add(String...val) throws Exception{try {conn = DBUtils.getConnectiOn();StringBuilder sql = new StringBuilder().append("INSERT INTO U_STUDENT(SNO,SNAME,SEX,BIRTHDAY,CLASSNO").append(",TEL,EMAIL,ADDRESS,USERID)").append("    VALUES (S_U_STUDENT_SNO.NEXTVAL,?,?,TO_DATE(?,'YYYY-MM-DD'),").append("?,?,?,?,?)");//System.out.println("SQL :" + sql.toString());pstm = conn.prepareStatement(sql.toString());int size = val.length;for (int i = 0; i < size; i++) {pstm.setObject(i + 1, val[i]);}return pstm.executeUpdate() > 0;} finally{DBUtils.close(pstm);DBUtils.close(conn);}}}

对用户表的操作类：UserInfoService.class

package com.edu.services;import java.sql.CallableStatement;import java.sql.Connection;import java.sql.PreparedStatement;import java.sql.ResultSet;import com.edu.db.DBUtils;public class UserInfoServices {private Connection conn = null;private PreparedStatement pstm = null;private ResultSet rs = null;private CallableStatement cstm = null;public String queryPriv(String userid) throws Exception{try{conn = DBUtils.getConnectiOn();StringBuilder sql = new StringBuilder().append("SELECT PRIV").append("  FROM USER_INFO U").append(" WHERE U.USERID = ?");pstm = conn.prepareStatement(sql.toString());pstm.setObject(1, userid);//System.out.println("-" + userid + "-");rs = pstm.executeQuery();String priv = null;if(rs != null){while(rs.next()){priv = rs.getString(1);}}return priv;}finally{DBUtils.close(rs);DBUtils.close(pstm);DBUtils.close(conn);}}public void delUser(String userid) throws Exception{try {conn = DBUtils.getConnectiOn();String sql = "{call pro_s_u_userid(?)}";cstm = conn.prepareCall(sql);cstm.setString(1, userid);cstm.execute();} finally{DBUtils.close(cstm);DBUtils.close(conn);}}public boolean addUser(String username,String passwd,String priv) throws Exception{try{conn = DBUtils.getConnectiOn();StringBuilder sql = new StringBuilder().append("INSERT INTO USER_INFO(USERID,USERNAME,PASSWD,PRIV,REGISTERTIME)").append("       VALUES (S_USER_INFO_USERID.NEXTVAL,?,?,?,SYSDATE)");pstm = conn.prepareStatement(sql.toString());pstm.setString(1, username);pstm.setString(2, passwd);pstm.setString(3, priv);return pstm.executeUpdate() > 0;} finally{DBUtils.close(pstm);DBUtils.close(conn);}}public boolean updatepwd(String userid,String pwd,String newpwd) throws Exception{try{conn = DBUtils.getConnectiOn();StringBuilder sql = new StringBuilder().append("UPDATE USER_INFO U").append("   SET U.PASSWD = ?").append(" WHERE U.USERID = ?").append("   AND U.PASSWD = ?");pstm = conn.prepareStatement(sql.toString());pstm.setString(1, newpwd);pstm.setString(2, userid);pstm.setString(3, pwd);return pstm.executeUpdate() > 0;} finally{DBUtils.close(pstm);DBUtils.close(conn);}}/** * 用户登录 * @param username * @param passwd * @param priv * @return * @throws Exception */public String login(String username,String passwd,String priv) throws Exception{try {conn = DBUtils.getConnectiOn();StringBuilder sql = new StringBuilder().append("SELECT U.USERID ").append("  FROM USER_INFO U ").append(" WHERE U.PASSWD = ? ").append("   AND U.PRIV =? ").append("   AND U.USERNAME = ? ");pstm = conn.prepareStatement(sql.toString());pstm.setObject(1, passwd);pstm.setObject(2, priv);pstm.setObject(3, username);rs = pstm.executeQuery();String userid = null;while(rs.next()){userid = rs.getString(1);}return userid;} finally{DBUtils.close(rs);DBUtils.close(pstm);DBUtils.close(conn);}}}

接下来只需要在对应的按钮执行对应的方法就行了！

一个简单的Swing程序就完成了！
