数据库你自己弄吧，我没时间弄了！初学得多动手哦
(高分)急求连接数据库的JAVA学生信息管理系统源代码
你要连的数据库是SQL 还是ORACLE
但是代码都查不多
下面的是连接SQL数据库的代码
你需要先创建个数据库,还有表,表的字段是登陆名和密码
下面的"SA" 是登陆名 "111111" 是密码
ORACLE 和这个查不多
import java.sql.*;//做数据库时候必须要引入的包
import com.microsoft.jdbc.sqlserver.SQLServerDriver;
public class DBFactory {
Connection Conn=null;
PreparedStatement Stmt=null;
ResultSet Rs=null;
String driverName="com.microsoft.jdbc.sqlserver.SQLServerDriver";
String OracleUserName="sa";
String OracleUserPwd="111111";
String ConnUrl="jdbc:sqlserver://localhost:1433;databaseName=news";
public Connection getConnection()
{
try {
Class.forName(driverName);
} catch (ClassNotFoundException ex) {
System.out.println("加载驱动程序有错误");
}
try {
Conn = DriverManager.getConnection(ConnUrl, OracleUserName,OracleUserPwd);
} catch (SQLException ex1) {
System.out.print("取得连接的时候有错误，请核对用户名和密码");
}
return Conn;
}
这个是连接ORACLE数据库代码
import java.sql.*;
import oracle.jdbc.driver.OracleDriver;
public class DBFactory {
Connection Conn=null;
PreparedStatement Stmt=null;
ResultSet Rs=null;
String driverName="oracle.jdbc.driver.OracleDriver";
String OracleUserName="scott";
String OracleUserPwd="tiger";
String ConnUr1="jdbc:oracle:thin:@locahost:1521:Ora";
public Connection getConnection()
{
try {
Class.forName(driverName);
} catch (ClassNotFoundException ex) {
System.out.println("加载驱动程序有错误");
}
try {
Conn = DriverManager.getConnection(ConnUr1, OracleUserName,OracleUserPwd);
} catch (SQLException ex1) {
System.out.print("取得连接时有错误，请核对用户名和密码");
}
return Conn;
}
希望能追加分数谢谢！
用JAVA编程的通过SQL连接数据库的商品库存管理系统的源代码
package com.company.dao;
import java.sql.Connection;import java.sql.DriverManager;import java.sql.PreparedStatement;import java.sql.ResultSet;import java.sql.SQLException;import java.sql.Statement;public class BaseDao {
// 数据库驱动
String driver = "com.microsoft.sqlserver.jdbc.SQLServerDriver";
//url
String url = "jdbc:sqlserver://数据库ip:端口号;databaseName=数据库名;";
//用户名
String uname = "数据库用户名";
//密码
String pwd = "数据库密码";
/**
* 获得连接对象
* @return
*/
protected Connection getCon(){
//返回的连接
Connection con = null;
try {
//载入驱动
Class.forName(driver);
//得到连接
con = DriverManager.getConnection(url, uname, pwd);
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SQLException e) {
e.printStackTrace();
}
return con;
}
/**

*/
protected void closeDB(Connection con, Statement stmt, ResultSet rs){
if(rs != null){
try {
//关闭结果集
rs.close();
rs = null;
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
if(stmt != null){
try {
//关闭语句对象
stmt.close();
stmt = null;
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
if(con != null){
try {
//关闭连接对象
con.close();
con = null;
} catch (SQLException e) {
e.printStackTrace();
}
}
}
protected void closeDB(Connection con, PreparedStatement pstmt, ResultSet rs){
if(rs != null){
//关闭结果集
try {
rs.close();
rs = null;
} catch (SQLException e) {
e.printStackTrace();
}
}
if(pstmt != null){
try {
pstmt.close();
pstmt = null;
} catch (SQLException e) {
e.printStackTrace();
}
}
if(con != null){
try {
con.close();
con = null;
} catch (SQLException e) {
e.printStackTrace();
}
}
}
这个是我写的一个基本的连接sql2005数据库的代码,.! 不知道你能不能用,! 你看一下吧, 连接的时候需要sqljdbc.jar数据库驱动,!
高分！！用Java和数据库实现银行管理系统源代码，要可以用的，采纳了再加分
蛇精病，课程设计吧？我有全年级的课程设计，图书馆管理系统，煤气公司进出货系统，银行管理系统，教学管理系统等等。。。。
