在《
JDBC Driver For SQL2000/2005/2008》一文中，邀月介绍了如何下载并使用jdbc连接SQL Server,
今天有人问起，如何以windows集成方式连接SQL Server,这个以前真没试过。
于是，打开netBeans测试了一下，代码如下：
/*
* To change this template, choose Tools | Templates
* and open the template in the editor.
*/
package testsqlconn;
import java.sql.*;
import com.microsoft.sqlserver.jdbc.*;
/** *//**
*
* @author: Administrator:downmoon(3w@live.cn)
* @date:2009-9-23 18:42:32
* @Encoding:UTF-8
* @File:TestSqlbyDS/TestSqlbyDS.java
* @Package:testsqlconn
*/
public class TestSqlbyDS {
public TestSqlbyDS(){}
public void GetResutls()
{
// Declare the JDBC objects.
Connection con = null;
CallableStatement cstmt = null;
ResultSet rs = null;
try {
// Establish the connection.
SQLServerDataSource ds = new SQLServerDataSource();
ds.setIntegratedSecurity(true);
ds.setServerName("ap4\\agronet08");//数据库实例名
ds.setPortNumber(1433);
ds.setDatabaseName("AdventureWorksLT2008");//Database Name
con = ds.getConnection();
// Execute a SQL that returns some data.
//cstmt = con.prepareCall("{call dbo.uspGetEmployeeManagers(?)}");
//cstmt.setInt(1,50);
cstmt = con.prepareCall(" select top 10 * from [SalesLT].[Product] ");//Sql
rs = cstmt.executeQuery();
// Iterate through the data in the result set and display it.
while (rs.next()) {
System.out.println("Product: " + rs.getString("Name") + ", " + rs.getString("ProductNumber"));
System.out.println("ListPrice: " + rs.getString("ListPrice"));
System.out.println();
}
} // Handle any errors that may have occurred.
catch (Exception e) {
e.printStackTrace();
} finally {
if (rs != null) {
try {
rs.close();
} catch (Exception e) {
}
}
if (cstmt != null) {
try {
cstmt.close();
} catch (Exception e) {
}
}
if (con != null) {
try {
con.close();
} catch (Exception e) {
}
}
}
}
}
结果提示：找不到
sqljdbc_auth.dll,到下载的压缩包里看了下：auth\x86,auth\x64\,auth\IA64下都有该文件，直接复制auth\x86\sqljdbc_auth.dll到
E:\Java\jdkUpdate\jre\lib\ext\下，这是本机的jre路径。
然后运行。成功！
后来再试了下，发现直接用URL方式也可以实现：
代码如下：
Java
/*
* To change this template, choose Tools | Templates
* and open the template in the editor.
*/
package testsqlconn;
import java.sql.*;
/** *//**
*
* @author: Administrator:downmoon(3w@live.cn)
* @date:2009-9-23 18:42:32
* @Encoding:UTF-8
* @File:TestSqlByURL/TestSqlByURL.java
* @Package:testsqlconn
*/
public class TestSqlByURL {
public TestSqlByURL() {
}
public void GetResults() {
// Create a variable for the connection string.
String connectionUrl = "jdbc:sqlserver://ap4\\agronet08:1433;databaseName=AdventureWorksLT2008;integratedSecurity=true;";
// Declare the JDBC objects.
Connection con = null;
Statement stmt = null;
ResultSet rs = null;
try {
// Establish the connection.
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
con = DriverManager.getConnection(connectionUrl);
// Create and execute an SQL statement that returns some data.
String SQL = "SELECT TOP 10 * FROM [SalesLT].[Product]";
stmt = con.createStatement();
rs = stmt.executeQuery(SQL);
// Iterate through the data in the result set and display it.
while (rs.next()) {
System.out.println(rs.getString(2) + " " + rs.getString(3));
}
} // Handle any errors that may have occurred.
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) {
}
}
}
}
}
如果是用户名加密码的URL方式，则不需要
sqljdbc_auth.dll,简单多了：
Java
/*
* To change this template, choose Tools | Templates
* and open the template in the editor.
*/
package testsqlconn;
import java.sql.*;
import com.microsoft.sqlserver.jdbc.*;
/** *//**
*
* @author: Administrator:downmoon(3w@live.cn)
* @date:2009-9-23 18:42:32
* @Encoding:UTF-8
* @File:TestSqlUserPwdURL/TestSqlUserPwdURL.java
* @Package:testsqlconn
*/
public class TestSqlUserPwdURL {
public TestSqlUserPwdURL(){}
public static void ShowProduct(String ip,String dbName,String user,String pwd,int port,String sql) {
try {
// ## DEFINE VARIABLES SECTION ##
// define the driver to use
String driver = "com.microsoft.sqlserver.jdbc.SQLServerDriver";
// the database name
//String dbName = "AdventureWorksLT2008";
// define the Derby connection URL to use
String connectionURL = "jdbc:sqlserver://"+ip+":"+port+";databaseName=" + dbName;
// System.out.println(connectionURL);
Connection conn = null;
// Beginning of JDBC code sections
// ## LOAD DRIVER SECTION ##
Class.forName(driver);
System.out.println(driver + " loaded. ");
conn = DriverManager.getConnection(connectionURL, user, pwd);
Statement s = conn.createStatement();
ResultSet rs = s.executeQuery(sql);
while (rs.next()) {
System.out.println("ID : " + rs.getInt(1));
System.out.println("Name : " + rs.getString(2));
System.out.println("Number: " + rs.getString(3));
System.out.println("Time: " + rs.getString(4));
System.out.println();
}
rs.close();
s.close();
conn.close();
} catch (Exception e) {
System.out.println("Exception: " + e);
e.printStackTrace();
}
}
}
调用：
TestSqlUserPwdURL test3=new TestSqlUserPwdURL();
String sql="SELECT top 10 ProductID,[Name],ProductNumber,Modifieddate FROM [SalesLT].[Product] ";
test3.ShowProduct("192.168.30.99\\agronet08", "AdventureWorksLT2008", "sa", "sa", 1433, sql);
小结：java的jdbc集成windows方式连接共有两种方式：data source object和URL方式，分别见第一种和第二种。
