JDBC方式（區別于mybatis方式）

Java連接MySql插入數據的代碼

package com.chendan.maven;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;

public class MavenTest {
    public static void main(String[] args) throws Exception {
        String driver = "com.mysql.jdbc.Driver"; // 獲取mysql數據庫的驅動類
        String url = "jdbc:mysql://10.0.0.30:3306/test?&useSSL=false"; // 連接數據庫（test是數據庫名）
        String user = "chendan";// 連接mysql的用戶名
        String password = "123456";// 連接mysql的密碼
        String insertsql = "insert into t1 values(?,?)";
        String querysql = "select * from t1";

        Class.forName(driver);
        Connection conn = DriverManager.getConnection(url, user, password);
        conn.setAutoCommit(false);
        PreparedStatement statement = conn.prepareStatement(insertsql);
        statement.setInt(1, 1);
        statement.setString(2, "Tom");

        statement.executeUpdate();
        conn.commit();

        ResultSet rst = statement.executeQuery(querysql);
           while (rst.next()) {
                System.out.println(rst.getInt(1) + "\t" + rst.getString(2));
            }

    }
