在maven项目pom.xml中到入驱动包(以下是驱动包代码)

mysql

mysql-connector-java

8.0.15

导入成功会看到Maven Dependencies下有个mysql-connector-Java包

然后按下面步骤：

package com.base.day16;

import java.sql.Connection;

import java.sql.DriverManager;

import java.sql.ResultSet;

import java.sql.SQLException;

import java.sql.Statement;

public class JdbcTest {

public static void main(String[] args) {

// TODO Auto-generated method stub

try {

//加载驱动程序

Class.forName("com.mysql.cj.jdbc.Driver");

//创建连接

//java10为数据库名

String url="jdbc:mysql://localhost:3306/java10?useSSL=false&serverTimezone=UTC";

String username="用户名";

String userpwd="密码";

Connection conn = DriverManager.getConnection(url,username,userpwd);

//创建Statement，执行sql

Statement st=conn.createStatement();

ResultSet rs=st.executeQuery("select sname,sage,ssex from student1");

while(rs.next()){

System.out.println("名字"+rs.getString("sname"));

System.out.println("年齡"+rs.getInt("sage"));

System.out.println("性別"+rs.getString("ssex"));

}

//关闭连接

rs.close();

st.close();

conn.close();

} catch (ClassNotFoundException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (SQLException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

}
