基于SSM+MVC三层架构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~

超市会员管理系统

1. 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

2. 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

3. 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

4. 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

mybatis-config.xml

MyBatis配置文件，配置数据库信息及实体类别名，绑定**Mapperxml文件，打印日志

applicationContext.xml

Spring配置文件，注册bean，整合mybatis，注册接口，配置事务，切面

spring-mvc.xml

SpringMVC配置文件，配置视图解析器，文件上传，开启注解开发

配置web.xml

拦截用户的所有请求，初始化spring容器，过滤，编码

log4j.properties

日志输出定义

RouteController

路由跳转，携带数据跳转到指定页面并加载

package com.wanshi.controller;

import com.wanshi.bean.VipInfo;
import com.wanshi.bean.VipLevel;
import com.wanshi.service.VipInfoService;
import com.wanshi.service.VipLevelService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;

import java.util.List;
import java.util.logging.Level;

@Controller
@RequestMapping("/route")
public class RouteController {

    @Autowired
    @Qualifier("VipLevelServiceImpl")
    private VipLevelService vipLevelService;
    @Autowired
    private VipInfoService vipInfoService;

    @RequestMapping("/add")
    public String add(Model model) {
        List list = vipLevelService.list();
        model.addAttribute("levelList", list);
        return "add";
    }

    @RequestMapping("/update/{id}")
    private String update(@PathVariable("id") Integer id, Model model) {
        VipInfo vipInfo = vipInfoService.getByVip(id);
        List list = vipLevelService.list();
        model.addAttribute("vip", vipInfo);
        model.addAttribute("levelList", list);
        return "edit";
    }
}

VipInfoController

package com.wanshi.controller;

import com.wanshi.bean.Page;
import com.wanshi.bean.VipInfo;
import com.wanshi.service.VipInfoService;
import com.wanshi.utils.FileUtil;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.multipart.MultipartFile;

import javax.servlet.http.HttpServletRequest;
import java.io.File;
import java.io.IOException;
import java.io.InputStream;
import java.util.List;
import java.util.UUID;

@Controller
@RequestMapping("/vip")
public class VipInfoController {

    @Autowired
    @Qualifier("VipInfoServiceImpl")
    private VipInfoService vipInfoService;

    private static final Integer PAGE_SIZE = 2;

    @RequestMapping("/vip_list")
    public String list(String pageNumb, VipInfo vipInfo, Model model) {
        Integer currentNumb = 1;
        if (pageNumb != null && !pageNumb.equals("")) {
            currentNumb = Integer.valueOf(pageNumb);
        }
        Page pager = vipInfoService.list(currentNumb, PAGE_SIZE, vipInfo.getVip_name(), vipInfo.getVip_phone(), vipInfo.getVip_email());
        model.addAttribute("pager", pager);
        model.addAttribute("vipName", vipInfo.getVip_name());
        model.addAttribute("vipPhone", vipInfo.getVip_phone());
        model.addAttribute("vipEmail", vipInfo.getVip_email());
        return "list";
    }

    @RequestMapping("/addHandle")
    public String addHandle(MultipartFile head_pic, HttpServletRequest request) {
        try {
            String vipName = request.getParameter("vip_name");
            String vipLevel = request.getParameter("vip_level");
            String vipPhone = request.getParameter("vip_phone");
            String vipEmail = request.getParameter("vip_email");
            String finalFileName = FileUtil.upload(head_pic, "");
            //将数据装载为对象
            VipInfo vipInfo = new VipInfo();
            vipInfo.setVip_name(vipName);
            vipInfo.setVip_level(Integer.valueOf(vipLevel));
            vipInfo.setVip_phone(vipPhone);
            vipInfo.setVip_email(vipEmail);
            vipInfo.setHead_pic(finalFileName);
            vipInfoService.insert(vipInfo);
        } catch (IOException e) {
            e.printStackTrace();
        }
        return "redirect:/vip/vip_list";
    }


    @RequestMapping("/delete/{id}")
    public String delete(@PathVariable("id") Integer id) {
        vipInfoService.delete(id);
        return "redirect:/vip/vip_list";
    }

    @RequestMapping("/editHandle")
    public String editHandle(MultipartFile head_pic, HttpServletRequest request) {
        try {
            String vipId = request.getParameter("id");
            String vipName = request.getParameter("vip_name");
            String vipLevel = request.getParameter("vip_level");
            String vipPhone = request.getParameter("vip_phone");
            String vipEmail = request.getParameter("vip_email");
            String vipStatus = request.getParameter("status");
            String oldHeadPic = request.getParameter("old_head_pic");

            String finalFileName = FileUtil.upload(head_pic, oldHeadPic);
            //将数据装载为对象
            VipInfo vipInfo = new VipInfo();
            vipInfo.setId(Integer.valueOf(vipId));
            vipInfo.setVip_name(vipName);
            vipInfo.setVip_level(Integer.valueOf(vipLevel));
            vipInfo.setVip_phone(vipPhone);

            vipInfoService.update(vipInfo);
        } catch (IOException e) {
            e.printStackTrace();
        }
        return "redirect:/vip/vip_list";
    }
}

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;
    }

}
