Java連接SQLServer2008(常用數據庫連接三)

1.確定安裝好SQLServer2008數據庫登錄數據庫中建立一個新數據庫，並創建一張表，內容如下圖所示：

2.eclipse或者Myeclipse中建立Java工程，導入連接sqlserver2008在jar包sqljdbc4.jar，下載地址爲http://download.csdn.net/detail/whzhaochao/6414981

3.建立iConn.java接口，代碼如下：

package com.zhaochao.dba;

import java.sql.Connection;
public interface iConn {
    Connection getConn();
}

4.建立連接sqlserver2008類實現iConn接口

代碼如下：

注意修改連接數據庫的用戶名和密碼以及數據庫名

package com.zhaochao.dba;

import java.sql.Connection;
import java.sql.DriverManager;

public class SQLServerConn implements iConn {

    private static final String DBDRIVER = "com.microsoft.jdbc.sqlserver.SQLServerDriver" ;
    private static final String DBURL = "jdbc:sqlserver://localhost:1433;databaseName=zhaochao" ;
    private static final String DBUSER = "admin" ;
    private static final String DBPASS = "admin";
    private Connection conn=null;
    @Override
    public Connection getConn() {
        // TODO Auto-generated method stub
        try {
            Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
            this.conn=DriverManager.getConnection(DBURL, DBUSER, DBPASS);

        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        return this.conn;
    }

}

5.測試連接代碼：

package com.zhaochao.dba;

import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;

public class Test {

    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub
    //  TestMySQL();
    //  TestOracle();
    //  TestDB2();
        TestSQLServer();
    //  TestAccess();

    }

    private static void TestSQLServer() {
        Connection conn=null;
        PreparedStatement ps=null;
        ResultSet rs=null;
        iConn iconn=new SQLServerConn();
        conn=iconn.getConn();
        String sql="select * from zhaochao";

        try {
            ps=conn.prepareStatement(sql);
            rs=ps.executeQuery();
            while(rs.next()){
                System.out.println(rs.getString(1)+"|"+rs.getString(2)+"|"+rs.getString(3));
            }
        } catch (SQLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }finally{
            if(conn!=null){
                try {
                    conn.close();
                } catch (SQLException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
            }
            if(ps!=null){
                try {
                    ps.close();
                } catch (SQLException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
            }
            if(rs!=null){
                try {
                    rs.close();
                } catch (SQLException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
            }
        }
    }

}

6.測試結果：

1|admin     |admin
2|zhaochao  |zhaochao
