关于#JDBC#的问题，如何解决？

Question

package ga;

import java.sql.*;

public class Main {
    public static void main(String[] args) throws ClassNotFoundException, SQLException {
    //连接数据库
        Class.forName("com.mysql.jdbc.Driver");

        String url = "jdbc:mysql://127.0.0.1:3306//test";
        String username = "root";
        String password = "000";
        Connection conn = DriverManager.getConnection(url,username,password);


        String id = "cxk";
        String title = "1";
        String description = "dawfaw";
        String time = "2012-01-01";
        String gtime ="0000000000";

        String sql = "insert into ac (id, title, description, time, gtime) values (?, ?, ?, ?, ?)";

        PreparedStatement pstmt = conn.prepareStatement(sql);
        pstmt.setString(1, id);
        pstmt.setString(2, title);
        pstmt.setString(3, description);
        pstmt.setString(4, time);
        pstmt.setString(5, gtime);

        int count = pstmt.executeUpdate();  //受影响的函数

        System.out.println(count > 0);  //判断是否成功插入
//释放资源
        pstmt.close();
        conn.close();
    }
}

运行代码后表还是空的，哪里有问题？

Answer 1

这里有输出么，输出内容是什么，还是说没输出，加个异常捕获，打印下看看是不是报错了
