基于SSM+MVC三层架构实现超市会员管理系统
【摘要】 基于SSM+MVC三层架构实现超市会员管理系统
基于SSM实现超市会员管理系统
大家好，本周为大家带来一个基于SSM的超市会员管理系统，干货满满，内容详细哦~
项目简介
超市会员管理系统
-
查询会员信息，能够根据多条件进行查询，并将查询的结果进行分页展示，展示效果按照前5后4的样式进行展示
细节：
(1) 点击多条件搜索后，在表单中回显搜索的内容
(2) 点击分页码时，要把多条件搜索框中的条件传递到控制器
(3) 点击分页码时，如果当前是第一页，上一页要禁用，如果当前是最后一页，下一页要禁用
(4) 分页导航显示当前页的前5页和当前页的后4页
-
修改会员信息，点击修改按钮后先展示编辑表单，并在编辑表单中回显要修改的内容，点击提交后，进行更新操作
细节
(1) 在编辑表单中，如果该会员有头像要把头像回显
(2) 如果上传了新的头像，则使用新的替换旧的头像，如果没有上传新的头像，则使用旧的头像
-
删除会员信息，点击删除按钮后删除对应的会员信息并将上传的会员头像删除
-
新增会员信息，点击新增按钮后，新增页需要有会员头像上传，上传完毕头像后将头像存储在硬盘，数据库存储对应的图片名称
效果图
数据表准备
t_vip_info
CREATE TABLE `t_vip_info` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`vip_name` varchar(32) COLLATE utf8mb4_unicode_ci DEFAULT NULL COMMENT '会员名称',
`vip_level` int(11) DEFAULT NULL COMMENT '会员所属级别，关联t_vip_level表',
`head_pic` varchar(256) COLLATE utf8mb4_unicode_ci DEFAULT NULL COMMENT '会员头像',
`vip_phone` varchar(11) COLLATE utf8mb4_unicode_ci DEFAULT NULL COMMENT '会员电话',
`vip_email` varchar(32) COLLATE utf8mb4_unicode_ci DEFAULT NULL COMMENT '会员邮箱',
`vip_status` int(11) DEFAULT '1' COMMENT '会员状态，0：已注销，1：未注销',
`create_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT '办理日期',
PRIMARY KEY (`id`)
)
t_vip_level
CREATE TABLE `t_vip_level` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`level_name` varchar(32) COLLATE utf8mb4_unicode_ci DEFAULT NULL COMMENT '会员级别：1：普通，2：白金会员，3：钻石会员，4：金牌会员',
PRIMARY KEY (`id`)
)

FileUtil
工具类，封装了文件上传
package com.wanshi.utils;
import org.springframework.web.multipart.MultipartFile;
import java.io.File;
import java.io.IOException;
import java.io.InputStream;
import java.util.UUID;
public class FileUtil {
public static String upload(MultipartFile head_pic, String oldHeadPic) throws IOException {
String finalFileName = "";
if (head_pic.getSize() > 0) {
InputStream inputStream = head_pic.getInputStream();
String originalFilename = head_pic.getOriginalFilename();
new File("C:/uploads/img/"+oldHeadPic).delete();
//生成目标文件
String destName = UUID.randomUUID().toString().replace("-", "");
//获取源文件的后缀名
String extName = originalFilename.substring(originalFilename.lastIndexOf("."));
finalFileName = destName+extName;
//目标文件
File file = new File("C:/uploads/img/"+finalFileName);
if (!file.exists()) {
file.mkdirs();
}
//开始上传
head_pic.transferTo(file);
}
return finalFileName;
}
}
