java中如何以windows集成方式连接SQL Server

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：

/*

package testsqlconn;
import java.sql.*;
import com.microsoft.sqlserver.jdbc.*;
/** *//**

 * @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：

/*

package testsqlconn;
import java.sql.*;
/** *//**

 * @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：

/*

 * and open the template in the editor.

package testsqlconn;
import java.sql.*;
import com.microsoft.sqlserver.jdbc.*;
/** *//**

 * @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();
        }
    }
}

测试代码：

TestSqlUserPwdURL test3=new TestSqlUserPwdURL();
       String sql="SELECT top 10  ProductID,[Name],ProductNumber,Modifieddate FROM  [SalesLT].[Product] order by Modifieddate desc ";
       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。
