連接數據庫
測試代碼
import java.sql.*;
public class MysqlJdbc {
public static void main(String args[]) {
try {
Class.forName("com.mysql.cj.jdbc.Driver"); //加載MYSQL JDBC驅動程序
//Class.forName("org.gjt.mm.mysql.Driver");
System.out.println("Success loading Mysql Driver!");
}
catch (Exception e) {
System.out.print("Error loading Mysql Driver!");
e.printStackTrace();
}
try {
Connection connect = DriverManager.getConnection(
"jdbc:mysql://localhost:3306/li_ying?useUnicode=true&characterEncoding=utf8&serverTimezone=GMT%2B8&useSSL=false","root","123456");
//連接URL為 jdbc:mysql//服務器地址/數據庫名 ，后面的2個參數分別是登陸用戶名和密碼
System.out.println("Success connect Mysql server!");
Statement stmt = connect.createStatement();
ResultSet rs = stmt.executeQuery("select * from user");
//user 為你表的名稱
while (rs.next()) {
System.out.println(rs.getString("name"));
}
}
catch (Exception e) {
System.out.print("get data error!");
e.printStackTrace();
}
}
