编写Java程序，使用JDBC连接SQL Server数据库

package com.demo.T1;
import java.sql.Connection;
import java.sql.DriverAction;
import java.sql.DriverManager;
import java.sql.SQLException;
public class DbConnection {
  //驱动类名
  private static final String DRIVERNAME = "com.mysql.jdbc.Driver";
  //驱动地址描述URL
  private static final String URL = "jdbc:mysql://192.168.2.101:3306/eshop_db";
  //账号
  private static final String NAME = "test";
  //密码
  private static final String PWD = "123";
  //1、加载驱动
  static {
    try {
      Class.forName(DRIVERNAME);
    } catch (ClassNotFoundException e) {
      e.printStackTrace();
    }
  }
  //2、获取一个数据库连接
  public static Connection getConnection() {
    Connection conc = null;
    try {
      conc = DriverManager.getConnection(URL, NAME, PWD);
    } catch (SQLException e) {
      e.printStackTrace();
    }
    return conc;
  }
  public static void main(String[] args) {
    //调用获取连接
    Connection conc = getConnection();
    System.out.println("连接对象是："+conc);
  }
}
