1. 注册数据库驱动
Class.forName("com.mysql.jdbc.Driver");
2. 获取连贯
`Connection conn = DriverManager.getConnection(“jdbc:mysql://localhost:3306/jt_db?characterEncoding=utf-8”,
"root", "root");`
3. 获取传输器
Statement stat = conn.createStatement();
4. 利用传输器发送 SQL 到服务器执行, 返回执行后果
`String sql = “select * from account”;
ResultSet rs = stat.executeQuery(sql);`
5. 处理结果
6. 避免注入攻打办法
`ComboPooledDataSource pool = new ComboPooledDataSource();
Connection conn = pool.getConnection();
String sql = “select * from user”;
PreparedStatement ps =conn.prepareStatement(sql);
ResultSet rs = ps.executeQuery();`
