课程信息管理系统

1.   创建一个Dynamic web project取名Ke

2在wecontent中创建以下几个jsp文件

Zhu.jsp

<%@page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

</head>

<frameset rows="100,*">
    <frame name="top" src="Top.jsp">
    <frameset cols="120,*">
    <frame name="left" src="Choice.jsp">
    <frame name="right" src="add.jsp">

3. 然后在Java Resources中创建一个Ke包

在包里创建以下几个class文件

util.java

package Ke;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;

public class util {
    String user="sa";
    String password="364624";
    String url="jdbc:sqlserver://localhost:1433;DatabaseName=XVQIU";
    public  Connection getConn(){
        Connection conn=null;
        try {
            Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
        } catch (ClassNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        try {
                conn=DriverManager.getConnection(url, user, password);
        } catch (Exception e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
        }
        return conn;
    }
    public void close(ResultSet rs, Statement state, Connection conn) {
        if(rs!=null)
        {
            try
            {
                rs.close();
            }
            catch(SQLException e)
            {
                e.printStackTrace();
            }
        }
        if(state!=null)
        {
            try
            {
                state.close();
            }
            catch(SQLException e)
            {
                e.printStackTrace();
            }
        }
        if(conn!=null)
        {
            try
            {
                conn.close();
            }
            catch(SQLException e)
            {
                e.printStackTrace();
            }
        }
    }
}

Test.java

package Ke;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;

public class util {
    String user="sa";
    String password="364624";
    String url="jdbc:sqlserver://localhost:1433;DatabaseName=XVQIU";
    public  Connection getConn(){
        Connection conn=null;
        try {
            Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
        } catch (ClassNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        try {
                conn=DriverManager.getConnection(url, user, password);
        } catch (Exception e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
        }
        return conn;
    }
    public void close(ResultSet rs, Statement state, Connection conn) {
        if(rs!=null)
        {
            try
            {
                rs.close();
            }
            catch(SQLException e)
            {
                e.printStackTrace();
            }
        }
        if(state!=null)
        {
            try
            {
                state.close();
            }
            catch(SQLException e)
            {
                e.printStackTrace();
            }
        }
        if(conn!=null)
        {
            try
            {
                conn.close();
            }
            catch(SQLException e)
            {
                e.printStackTrace();
            }
        }
    }
}

4右击build选择build path 中的configure build path 在弹出窗口右侧点击add extemal jars 导入jar包

5下载安装sql server 

创建名为Ke的数据库

并创建名为Ke_c的表

三个名为 Ke Tea Di 的列
