1.英才大学图书馆管理系统
功能点：用户登录、注册、密码修改，新增、修改、删除图书信息，实现图书外借与归还，查询图书信息（精确查找、模糊查找）
这个东西是数据库的一次实验
因为我常年不用java，这也算是一个java大型复健作业，不过由于对面向对象的思想，还有java的很多东西掌握不够牢固，在写的时候应该有很多莫名其妙的语法orz
另外建议swpu的朋友们还是仅供参考，找我要这份代码的人已经相当多了

一 数据库连接测试
首先是关于数据库的连接，老师也没有讲过，自己试了老久才连上，还是有很多坑的。
这里先给出一份测试连接的代码
import java.sql.*;
public class MySQLDemo {
public static void main(String[] args) {
System.out.println("数据库原理及应用");
String connectionUrl = "jdbc:sqlserver://localhost:1433;databaseName=MyDb"; //你要连的数据库
// Declare the JDBC objects.
Connection con = null;
Statement stmt = null;
ResultSet rs = null;
System.out.println("正在连接数据库和检索，请等待...");
try {
// Establish the connection.
//Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
con = DriverManager.getConnection(connectionUrl,"sa","123456"); //账号和密码，注意权限是否开了
// Create and execute an SQL statement that returns some data.
String SQL = "select * from IpTable "; //测试，改成你的表看是否成功
stmt = con.createStatement();
rs = stmt.executeQuery(SQL);
while (rs.next()) {
System.out.println(rs.getString(1) + "\t" + rs.getString(2) + "\t" + rs.getString(3) + "\t" + rs.getString(4));
}
}
catch (Exception e) {
e.printStackTrace();
}
finally {
if (rs != null) try {
rs.close(); } catch(Exception e) {
}
if (stmt != null) try {
stmt.close(); } catch(Exception e) {
}
if (con != null) try {
con.close(); } catch(Exception e) {
}
}
}
}
这一步的重点：
当然你想要连接的上数据库，你的连接账号权限设置肯定是不能忘记的。数据库初次下载后默认的是只有Windows身份验证模式，要将设置改一下。
然后还要在微软官网上下载对应的驱动包，导入eclipse，链接我也给一下https://docs.microsoft.com/zh-cn/sql/connect/jdbc/using-the-jdbc-driver?view=sql-server-2017
导入后的配置如图所示
