//1.导入驱动jar包
//2.注册驱动(mysql5之后的驱动jar包可以省略注册驱动的步骤)
//Class.forName("com.mysql.jdbc.Driver");
//3.获取数据库连接对象

conn = DriverManager.getConnection("jdbc:mysql://134.175.66.149:3306/test?" + "&rewriteBatchedStatements=true&serverTimezone=UTC","root","B5IWfkqW8uu36J");
//4.定义sql语句
String sql = "insert into user values(default,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)";
//5.获取执行sql的对象PreparedStatement
pstmt = conn.prepareStatement(sql);
//6.不断产生sql
