实例讲解3jar包连接sqlserver2000 - msbase.jar;mssqlserver.jar;msutil.jar

 

一、首先确保环境Ok，1、安装jdk，2、下载jdbc驱动。

其中msbase.jar;mssqlserver.jar;msutil.jar的下载：http://download.csdn.net/source/2474798

(很抱歉，上传时忘了改0资源分了，直接重新上传还不行)

 

二、建立如图工作环境：

 

简要说明一下各个文件的作用，按创建先后：

1、sqlserver_driver_lib.rar：下载的jdbc驱动；

2、msbase.jar;mssqlserver.jar;msutil.jar：解压缩得到的jar包文件；

3、新建 文本文档.txt：为了编写java代码与bat文件使用；

4、testsqlServer2000.java：java源码，内容如下

import java.<a href="/tag/sql/" target="_blank" class="keywords">sql</a>.ResultSet; import java.<a href="/tag/sql/" target="_blank" class="keywords">sql</a>.<a href="/tag/sql/" target="_blank" class="keywords">sql</a>Exception; import java.<a href="/tag/sql/" target="_blank" class="keywords">sql</a>.Statement; import java.<a href="/tag/sql/" target="_blank" class="keywords">sql</a>.*; public class test<a href="/tag/sql/" target="_blank" class="keywords">sql</a>Server2000 { //driver string static String JDBCDriver="com.microsoft.jdbc.<a href="/tag/sql/" target="_blank" class="keywords">sql</a>server.<a href="/tag/sql/" target="_blank" class="keywords">sql</a>ServerDriver"; //connection string String JDBCConnection="jdbc:microsoft:<a href="/tag/sql/" target="_blank" class="keywords">sql</a>server://data:1433;DatabaseName=master"; String userName = "sa"; String userPwd = "sa"; Connection conn=null; ResultSet rs=null; public test<a href="/tag/sql/" target="_blank" class="keywords">sql</a>Server2000() { try{ Class.forName(JDBCDriver);//load Driver } catch(<a href="/tag/javalangclass/" target="_blank" class="keywords">java.lang.class</a>NotFoundException e) { Sy<a href="/tag/stem/" target="_blank" class="keywords">stem</a>.err.println("Dbconnection ():"+e.getMessage());//catch exception } } public Connection connect() { try{//get connection conn=DriverManager.getConnection(JDBCConnection,userName,userPwd); Sy<a href="/tag/stem/" target="_blank" class="keywords">stem</a>.out.println("connect successful"); } catch(<a href="/tag/sql/" target="_blank" class="keywords">sql</a>Exception ex) { Sy<a href="/tag/stem/" target="_blank" class="keywords">stem</a>.err.println("connection():"+ex.getMessage()); } return conn; } public void close() { try { if(!this.conn.isClosed()) { this.conn.close(); Sy<a href="/tag/stem/" target="_blank" class="keywords">stem</a>.out.println("close successful"); } } catch (<a href="/tag/sql/" target="_blank" class="keywords">sql</a>Exception e) { // T<a href="/tag/odo/" target="_blank" class="keywords">odo</a> Auto-generated catch block e.<a href="/tag/printstacktrace/" target="_blank" class="keywords">printstacktrace</a>(); } } /** * @p<a href="/tag/ara/" target="_blank" class="keywords">ara</a>m args */ public static void main(String[] args) { // T<a href="/tag/odo/" target="_blank" class="keywords">odo</a> Auto-generated method stub test<a href="/tag/sql/" target="_blank" class="keywords">sql</a>Server2000 cdb=new test<a href="/tag/sql/" target="_blank" class="keywords">sql</a>Server2000(); cdb.connect(); Statement stmt; ResultSet rs; try { stmt = cdb.conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE); rs = stmt.executeQuery("select * from spt_monitor"); while(rs.next()) { String s=rs.getString(1); Sy<a href="/tag/stem/" target="_blank" class="keywords">stem</a>.out.println(s); } } catch (<a href="/tag/sql/" target="_blank" class="keywords">sql</a>Exception e) { // T<a href="/tag/odo/" target="_blank" class="keywords">odo</a> Auto-generated catch block e.<a href="/tag/printstacktrace/" target="_blank" class="keywords">printstacktrace</a>(); } cdb.close(); } }

5、javac.bat文件，用于编译java文件，其内容如下，双击执行得到testsqlServer2000.class

set path="C:/Program Files/Java/jdk1.6.0_11/bin; C:/Windows;C:/Windows/Command" set cla<a href="/tag/ssp/" target="_blank" class="keywords">ssp</a>ath=". ;C:/Program Files/Java/jdk1.6.0_11/lib/tools.jar" "C:/Program Files/Java/jdk1.6.0_11/bin/javac" test<a href="/tag/sql/" target="_blank" class="keywords">sql</a>Server2000.java pause

执行结果：

I:/workspace/java/test<a href="/tag/sql/" target="_blank" class="keywords">sql</a>Server2000>set path="C:/Program Files/Java/jdk1.6.0_11/ bin; C:/Windows;C:/Windows/Command" I:/workspace/java/test<a href="/tag/sql/" target="_blank" class="keywords">sql</a>Server2000>set cla<a href="/tag/ssp/" target="_blank" class="keywords">ssp</a>ath=". ;C:/Program Files/Java/jdk1 .6.0_11/lib/tools.jar" I:/workspace/java/test<a href="/tag/sql/" target="_blank" class="keywords">sql</a>Server2000>"C:/Program Files/Java/jdk1.6.0_11/bin/javac " test<a href="/tag/sql/" target="_blank" class="keywords">sql</a>Server2000.java I:/workspace/java/test<a href="/tag/sql/" target="_blank" class="keywords">sql</a>Server2000>pause 请按任意键继续. . .

6、testsqlServer2000.class 是java编译得到的字节码文件，虚拟机实际解析的文件

7、java.bat是调用java执行testsqlServer2000，其代码为：

@set path="C:/Program Files/Java/jdk1.6.0_11/bin; C:/Windows;C:/Windows/Command" @set cla<a href="/tag/ssp/" target="_blank" class="keywords">ssp</a>ath=". ;C:/Program Files/Java/jdk1.6.0_11/lib/tools.jar;ms<a href="/tag/sql/" target="_blank" class="keywords">sql</a>server.jar;msbase.jar;msutil.jar" "C:/Program Files/Java/jdk1.6.0_11/bin/java" test<a href="/tag/sql/" target="_blank" class="keywords">sql</a>Server2000 pause

双击执行结果

I:/workspace/java/test<a href="/tag/sql/" target="_blank" class="keywords">sql</a>Server2000>"C:/Program Files/Java/jdk1.6.0_11/bin/java" test<a href="/tag/sql/" target="_blank" class="keywords">sql</a>Server2000 connect successful 2000-08-06 01:30:31.687 close successful I:/workspace/java/test<a href="/tag/sql/" target="_blank" class="keywords">sql</a>Server2000>pause 请按任意键继续. . .
