JDBC以SQL Server身份验证方式连接SQL Server2014

1.正确下载并安装SQL Server2014下载地址：http://www.itellyou.cn/

2.安装JDK以及eclipse，配置好环境变量

3.登陆微软官网下载适合自己JDK版本的JDBC，网址：https://www.microsoft.com/zh-cn/download/details.aspx?id=11774

4.下载好JDBC之后双击打开会自动解压，打开解压包将适合自己的.jar文件复制到\Jre\lib\ext目录下，对应的dll文件复制到\Jre\bin目录下

5.打开eclipse，Windows->Preferences->Java->Installed JREs,选中相应的Jre点击Edit->Add External JARs..->选中刚刚复制进去的.jar文件，单机打开->finish->apply->ok

6.以SQL Server身份验证方式登陆SQL Server2014，编写测试代码进行测试

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

public class DBHelper{

private static final String url = "jdbc:sqlserver://localhost:1433;databasename=sales";//连接字符串
private static final String driverName = "com.microsoft.sqlserver.jdbc.SQLServerDriver";//驱动程序
private static final String user = "sa";//用户名
private static final String password = "225821zyy";//密码

public Connection conn = null;
public PreparedStatement pst = null;

public DBHelper(String sql){
try{
Class.forName(driverName);//加载驱动程序
conn = DriverManager.getConnection(url, user, password);//连接数据库
pst = conn.prepareStatement(sql);//预编译SQL语句
}catch(Exception e){
e.printStackTrace();
}
}

public void close(){
try{
this.conn.close();
this.pst.close();
}catch(SQLException e){
e.printStackTrace();
}
}
}
import java.sql.ResultSet;
import java.sql.SQLException;

public class Demo {

static String sql = null;
static DBHelper db1 = null;
static ResultSet ret = null;

public static void main(String[] args){

sql = "select * from Orders";
db1 = new DBHelper(sql);

try {
ret = db1.pst.executeQuery();//执行查询返回结果集
while(ret.next()){//逐行读取结果集
String orderId = ret.getString(1);
String customerId = ret.getString(2);
String salesId = ret.getString(3);
String orderDate = ret.getString(4);
System.out.println(orderId + "\t" + customerId + "\t" + salesId + "\t" + orderDate);
}
db1.pst.close();
db1.close();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

}
