Java UtilDate转SqlDate

在写入数据库时，如果使用的是JDBC框架，那么statement设置UtilDate的值会报错的，那么此时如何将UtilDate转为SqlDate呢？

使用Flink的自定义Sink写入数据到MySQL

这里就用到了原生的JDBC框架

package org.example.flink.user;

import org.apache.flink.configuration.Configuration;
import org.apache.flink.streaming.api.functions.sink.RichSinkFunction;

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

public class UserSink extends RichSinkFunction {

    Connection connection = null;
    PreparedStatement statement = null;

    @Override
    public void open(Configuration parameters) throws Exception {
        String url = "jdbc:mysql://localhost:3306/flink?autoReconnect=true&useUnicode=true&characterEncoding=utf8&serverTimezone=GMT%2B8&useSSL=false";
        connection = DriverManager.getConnection(url, "root", "root");
        statement = connection.prepareStatement("replace into user (id,username,password,address,email,profile,birthday,register_day,login_day,status,account,balance,age,sex,avatar,`level`) values (?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)");
    }

    @Override
    public void invoke(User user, Context context) throws Exception {
        //直接执行更新语句
        statement.setString(1, user.getId());
        statement.setString(2, user.getUsername());
        statement.setString(3, user.getPassword());
        statement.setString(4, user.getAddress());
        statement.setString(5, user.getEmail());
        statement.setString(6, user.getProfile());
        statement.setDate(7, new Date(user.getBirthday().getTime()));
        statement.setDate(8, new Date(user.getRegisterDay().getTime()));
        statement.setDate(9, new Date(user.getLoginDay().getTime()));
        statement.setInt(10, user.getStatus());
        statement.setBigDecimal(11, user.getAccount());
        statement.setBigDecimal(12, user.getBalance());
        statement.setInt(13, user.getAge());
        statement.setInt(14, user.getSex());
        statement.setString(15, user.getAvatar());
        statement.setInt(16, user.getLevel());
        statement.execute();
    }

    @Override
    public void close() throws Exception {
        statement.close();
        connection.close();
    }
}

思路：使用SqlDate的构造方法

使用SqlDate的构造方法，里面传UtilDate值的long类型的时间戳

statement.setDate(7, new Date(user.getBirthday().getTime()));
