JDBC之连接sql server数据库

1.添加JDBC的驱动包

 新建package命名为lib，将驱动包放入lib中，并build path。

2..创建jdbc.properties,将数据库配置写入该文件中

user=sa
password=数据库密码
url=jdbc:sqlserver://localhost:端口号（默认是1433）;DatabaseName=数据库名称
driverClass=com.microsoft.sqlserver.jdbc.SQLServerDriver

3.创建一个类，用于获取连接

 public static Connection getConnection() throws Exception {
        InputStream is = ClassLoader.getSystemClassLoader().getResourceAsStream("jdbc1/jdbc.properties");
        Properties pros = new Properties();
        pros.load(is);
        String user = pros.getProperty("user");
        String password = pros.getProperty("password");
        String url = pros.getProperty("url");
        String driverClass = pros.getProperty("driverClass");

        Class.forName(driverClass);

        Connection conn = DriverManager.getConnection(url,user,password);

        return conn;

    }

4.测试连接

@Test
    public void connectinTest() throws Exception {
        Connection conn = getConnection();
        System.out.println(conn);
        conn.close();
    }
