java使用windows验证方式连接sqlserver2008数据库

连接数据库的代码段：

package com.db;

import java.sql.*;

public class DButil {
    public static void main(String[] args) {
        Connection con = null;
        Statement stmt = null;
        ResultSet rs = null;
        String driver = "com.microsoft.sqlserver.jdbc.SQLServerDriver";
        String url = "jdbc:sqlserver://10.103.2.18:1433;databaseName=HCM;integratedSecurity=true;";//windows集成模式连接
        try {
            Class.forName(driver);
            con = DriverManager.getConnection(url);
            System.out.println("Connecting Successful!!!!!");
            stmt = con.createStatement();
            rs = stmt.executeQuery("select top 10 * from EmpData");
            while(rs.next()){
                System.out.println(rs.getString("EmployeeID")+"\t"+rs.getString("Name"));
            }
        } catch (SQLException e) {
            e.printStackTrace();
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        } finally{
            try {
                rs.close();
                stmt.close();
                con.close();
            } catch (SQLException e) {
                e.printStackTrace();
            }

        }

    }

}

出现的异常有：

 Failed to load the sqljdbc_auth.dll cause : no sqljdbc_auth in java.library.path

解決方案：

将sqljdbc_auth.dll加入C:\Windows\System32中

Exception in thread "main" java.lang.UnsatisfiedLinkError: com.microsoft.sqlserver.jdbc.AuthenticationJNI.GetDNSName(Ljava/lang/String[Ljava/lang/String;Ljava/util/logging/Logger;)I

解決方案：

1.将sqljdbc4.jar加入工程
2.将sqljdbc_auth.dll文件copy到以下目录

• c:/windows/system32
• eclipse所用jdk的bin目录下
• eclipse所用jre的bin目录下

<sqljdbc_auth.dll来自JDBC Driver X.0 for SQL Server，下载网址 http://www.microsoft.com/en-us/download/details.aspx?id=11774 >
