  • Java连载141-编辑实体类

一、安装mysql
首先在windows上安装mysql,地址：https://mirrors.huaweicloud.com/mysql/Downloads/MySQL-8.0/,找到最新版mysql-8.0.21-winx64.zip，点击下载
 
解压到某一个目录，然后设置环境变量，并生成data文件
141.1
 
后续操作请参考https://www.cnblogs.com/yunlongaimeng/p/12558638.html
141.2
 
坑区：一定要使用管理打开的方式打开cmd再进行命令行操作，否则就会报错
 
输入mysql -u root -p，进入之后首次启用无密码，直接回车即可，执行create database ibank创建数据库
141.3
二、实体类创建
该实体类就是用对必须存储的信息和相关行为进行建模。
package com.ibank.action;
 
import com.ibank.bean.Account;
import com.ibank.service.IAccountService;
import com.ibank.service.impl.AccountServiceImpl;

@SuppressWarnings("serial")
public class AccountAction extends ActionSupport {
private Account account;//账户信息
private IAccountService accservice = new AccountServiceImpl();

private double inputmoney;//存款金额
private double outputmoney;//取款金额
private int typeid;//账户类别id
private int flag;//标志位
private int ibankid;//开户行id
