本章学习点：插入数据到mysql数据库，PreparedStatement.executeUpdate();

package com.test1220.dao;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.SQLException;
import java.text.SimpleDateFormat;
import java.util.Date;

public class TestMysql {
	
	public static void main(String[] arg){
		Connection conn;
		PreparedStatement stmt;
		String driver = "com.mysql.jdbc.Driver";
		String url = "jdbc:mysql://localhost:3306/test001?useSSL=false";
		String user = "root";
		String password = "admin";
		String sql = "insert into persons values (?,?,?,?)";
		
		try {
			Class.forName(driver);
			conn = DriverManager.getConnection(url, user, password);
			stmt = (PreparedStatement) conn.prepareStatement(sql);
			stmt.setInt(1, 9958);
			stmt.setString(2, "eagle2");
			stmt.setString(3, "king3");
			stmt.setInt(4,2017);
			stmt.executeUpdate();
			
		} catch (ClassNotFoundException e) {
			// TODO 自动生成的 catch 块
			e.printStackTrace();
		} catch (SQLException e) {
			// TODO 自动生成的 catch 块
			e.printStackTrace();
		}
	}
