PrepareStatement部分的，运行时出错，希望可以帮我找找问题出在哪里

package com.zxy.zqk;

import com.zxy.zka.utils.JdbcUtils;

import java.sql.*;
import java.util.Date;

public class preparedStatementDemo {
    public static void main(String[] args) {
        Connection con = null;
        PreparedStatement st = null;
        ResultSet rs = null;
        try {
            con = JdbcUtils.getConnection();
            String sql = "INSERT INTO `users`(`id`,`NAME`,`PASSWORD`,`email`,`birthday`) VALUES(?,?,?,?,?)";
            st = con.prepareStatement(sql);
            st.setInt(1, 4);
            st.setString(2, "zhaoliu");
            st.setString(3, "123456");
            st.setString(4, "za@sina.com");
            st.setDate(5, new java.sql.Date(new Date().getTime()));
            int i = st.executeUpdate(sql);
            if (i > 0) {
                System.out.println("操作成功");
            }

        } catch (SQLException throwables) {
            throwables.printStackTrace();
        } finally {
            JdbcUtils.release(con, st, rs);
        }
    }
}

报错的内容：
Tue Aug 10 09:27:33 CST 2021 WARN: Establishing SSL connection without server's identity verification is not recommended. According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.

executeUpdate()，别用executeUpdate(String sql),不然你前面那一堆set就没啥用处了

数据库连接配置问题吧 提示你url后添加参数useSSL=false

数据库连接出现问题
需要添加ssl
