基于javaweb的仓库管理系统
一、系统简介
本项目采用eclipse工具开发，jsp+servlet技术编写，样式采用了layui前段框架，数据库采用的是mysql，navicat开发工具。
系统一共分为3个角色分别是：管理员，仓管员，供应商
二、模块简介
管理员
1、登录
2、仓管员管理
3、仓库管理
4、供应商管理
5、商品管理
6、出库入库管理
仓管员
1、登录
2、个人信息维护
3、查看商品信息
4、库存预警
5、商品申请
6、商品供应记录
7、商品出库入库
供应商
1、登录注册
2、个人信息维护
3、商品出库入库申请
4、个人申请记录

四、代码简介
1、登录
login.jsp中，用户填写用户名和密码，点击登录按钮，提交登录的form表单，请求后台的loginservlet类里面的login方法，验证登录后，跳转指定的页面
<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort() + path + "/";
%>
仓 库 管 理 系 统
private void login(HttpServletRequest request, HttpServletResponse response) {
// TODO Auto-generated method stub
removeAll(request,response);
String userName = request.getParameter("userName");
String password = request.getParameter("password");
String type = request.getParameter("type");
if(type.equals("1")){
Admin admin = new Admin();
admin.setUsername(userName);
admin.setPwd(password);
Admin admin1 = service.selectAdmin(admin);
try {
if (admin1 == null){
request.setAttribute("message", "管理员用户不存在或者密码错误");
request.getRequestDispatcher("/WEB-INF/views/login.jsp").forward(request, response);
}else {
request.getSession().setAttribute("admin",admin1);
request.getSession().setAttribute("flag",1);
request.getRequestDispatcher("/WEB-INF/views/main.jsp").forward(request, response);
}
} catch (Exception e) {
e.printStackTrace();
}
}else if(type.equals("2")){
Keeper keep = new Keeper();
keep.setUsername(userName);
keep.setPwd(password);
Keeper keep1 = service.selectKeeper(keep);
try {
if (keep1 == null){
request.setAttribute("message", "仓管员不存在或者密码错误");
request.getRequestDispatcher("/WEB-INF/views/login.jsp").forward(request, response);
}else {
request.getSession().setAttribute("keeper",keep1);
request.getSession().setAttribute("flag",2);
request.getRequestDispatcher("/WEB-INF/views/main.jsp").forward(request, response);
}
} catch (Exception e) {
e.printStackTrace();
}
}else if(type.equals("3")){
Supplier supplier = service.selectSupplier(userName,password);
try {
if (supplier == null){
request.setAttribute("message", "供应商不存在或者密码错误");
request.getRequestDispatcher("/WEB-INF/views/login.jsp").forward(request, response);
}else {
request.getSession().setAttribute("supplier",supplier);
request.getSession().setAttribute("flag",3);
request.getRequestDispatcher("/WEB-INF/views/main.jsp").forward(request, response);
}
} catch (Exception e) {
e.printStackTrace();
}
}else{
request.setAttribute("message", "账号不存在或者密码错误");
try {
request.getRequestDispatcher("/WEB-INF/views/login.jsp").forward(request, response);
} catch (Exception e) {
e.printStackTrace();
}
}
}注册代码
用户点击注册按钮，跳转注册页面，填写注册表单，提交代码到SupplierServlet里面addSupplier方法中，后台进行数据库的插入操作，这边注册的是供应商，管理员需要审核通过后，供应商才能登陆
<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort() + path + "/";
%>
private void addSupplier(HttpServletRequest request, HttpServletResponse response) {
// TODO Auto-generated method stub
String te = request.getParameter("te");
String names = request.getParameter("names");
String username = request.getParameter("username");
String pwd = request.getParameter("pwd");
String sex = request.getParameter("sex");
Supplier ss = service.selectSupplierByUsername(username);
Supplier s1 = new Supplier();
s1.setName(names);
s1.setUsername(username);
s1.setPwd(pwd);
s1.setSex(sex);
s1.setTimes(new SimpleDateFormat("yyyy-MM-dd HH:mm").format(new Date()));
s1.setState("1");
try {
if(te != null && te.equals("1")){
if(ss !=null){
request.setAttribute("message", "登录账号重复！");
request.getRequestDispatcher("/WEB-INF/views/register.jsp").forward(request,response);
}else{
service.addSupplier(s1);
request.getRequestDispatcher("/WEB-INF/views/login.jsp").forward(request, response);
}
}else{
if(ss !=null){
request.setAttribute("message", "登录账号重复！");
request.getRequestDispatcher("/WEB-INF/views/supplier/addSupplier.jsp").forward(request,response);
}else{
service.addSupplier(s1);
response.sendRedirect(request.getContextPath()+"/SupplierServlet?action=supplierList");
}
}
} catch (Exception e) {
e.printStackTrace();
}
}仓管员列表
分页查询仓管员的信息，返回给keepList.jsp，前端页面使用jstl进行遍历显示
private void keeperList(HttpServletRequest request, HttpServletResponse response) {
// TODO Auto-generated method stub
String p=request.getParameter("p");//接收页码
int pageSize=4;//每页显示5条
int pageNum=1; //默认第一页
if(p!=null){
pageNum= Integer.parseInt(p);
}
//调用分页查询
List list=service.geKeeperListPage(pageNum,pageSize);
//携带参数到页面
int nums=service.queryKeeperCount(); //查询总数
//计算总页数
int totalPage=(nums%pageSize==0)? (nums/pageSize):(nums/pageSize+1);
request.setAttribute("cp",pageNum); //当前页
request.setAttribute("tp",totalPage); //总页数
try {
request.removeAttribute("msg");
request.setAttribute("list" ,list);
request.getRequestDispatcher("/WEB-INF/views/keeper/keeperList.jsp").forward(request, response);
} catch (Exception e) {
e.printStackTrace();
}
}
