库存物资管理系统
库存物资管理系统
1.首先先建立一个名为course的数据库，在建立一个course名的表，然后添加几个字段
项目目录结构
2.源代码
先建立一个util的包，创建一个DBUtil的类，这是确定的，DBUtil.java
package util;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
/**
* 数据库连接工具
* @author zlj
*
*/
public class DBUtil {
public static String db_url = "jdbc:mysql://localhost:3306/course?useSSL=false";
public static String db_user = "root";
public static String db_pass = "199126";
public static Connection getConn () {
Connection conn = null;
try {
Class.forName("com.mysql.jdbc.Driver");//加载驱动
conn = DriverManager.getConnection(db_url, db_user, db_pass);
} catch (Exception e) {
e.printStackTrace();
}
return conn;
}
/**
* 关闭连接
* @param state
* @param conn
*/
public static void close (Statement state, Connection conn) {
if (state != null) {
try {
state.close();
} catch (SQLException e) {
e.printStackTrace();
}
}
if (conn != null) {
try {
conn.close();
} catch (SQLException e) {
e.printStackTrace();
}
}
}
public static void close (ResultSet rs, Statement state, Connection conn) {
if (rs != null) {
try {
rs.close();
} catch (SQLException e) {
e.printStackTrace();
}
}
if (state != null) {
try {
state.close();
} catch (SQLException e) {
e.printStackTrace();
}
}
if (conn != null) {
try {
conn.close();
} catch (SQLException e) {
e.printStackTrace();
}
}
}
}
然后添加创建一个course的类，定义变量。course.java
package entity;
public class Course {
private int id;
private String name;
private String changjia;
private String type;
private String guige;
private String shuliang;
private String riqi;
private String shijian;
private String danwei;
private String people;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getChangjia() {
return changjia;
}
public void setChangjia(String teacher) {
this.changjia = teacher;
}
public String gettype() {
return type;
}
public void settype(String classroom) {
this.type = classroom;
}
public String getGuige() {
return guige;
}
public void setGuige(String guige) {
this.guige = guige;
}
public String getShuliang() {
return shuliang;
}
public void setShuliang(String shuliang) {
this.shuliang = shuliang;
}
public String getRiqi() {
return riqi;
}
public void setRiqi(String riqi) {
this.riqi = riqi;
}
public String getShijian() {
return shijian;
}
public void setShijian(String shijian) {
this.shijian = shijian;
}
public String getDanwei() {
return danwei;
}
public void setDanwei(String danwei) {
this.danwei = danwei;
}
public String getpeople() {
return people;
}
public void setpeople(String people) {
this.people = people;
}
public Course() {}
public Course(int id, String name, String changjia, String type, String guige, String shuliang, String riqi, String shijian, String danwei, String people) {
this.id = id;
this.name = name;
this.changjia = changjia;
this.type = type;
this.guige = guige;
this.shuliang = shuliang;
this.riqi = riqi;
this.shijian = shijian;
this.danwei = danwei;
this.people = people;
}
public Course(String name, String changjia, String type, String guige, String shuliang, String riqi, String shijian, String danwei, String people) {
this.name = name;
this.changjia = changjia;
this.type = type;
this.guige = guige;
this.shuliang = shuliang;
this.riqi = riqi;
this.shijian = shijian;
this.danwei = danwei;
this.people = people;
}
}
然后建立一个Dao层，来封装数据，实现增删改查，courseDao.java
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
<style>
.a{
margin-top: 20px;
}
.b{
font-size: 20px;
width: 160px;
color: white;
background-color: greenyellow;
}
.tb, td {
border: 1px solid black;
font-size: 22px;
}
</style>
</head>
<body>
<div align="center">
<h1 style="color: red;">库存物资信息删除</h1>
<a href="index.jsp">返回主页</a>
<table class="tb">
<tr>
<td>商品名称</td>
<td>${course.name}</td>
</tr>
<tr>
<td>厂家</td>
<td>${course.changjia}</td>
</tr>
<tr>
<td>型号</td>
<td>${course.type}</td>
</tr>
<tr>
<td>规格</td>
<td>${course.guige}</td>
</tr>
<tr>
<td>数量</td>
<td>${course.shuliang}</td>
</tr>
<tr>
<td>日期</td>
<td>${course.riqi}</td>
</tr>
<tr>
<td>时间</td>
<td>${course.shijian}</td>
</tr>
<tr>
<td>单位</td>
<td>${course.danwei}</td>
</tr>
<tr>
<td>收送货人姓名</td>
<td>${course.people}</td>
</tr>
</table>
<div class="a">
<a onclick="return check()" href="CourseServlet?method=del&id=${course.id}">删 除</a>
</div>
</div>
<script type="text/javascript">
function check() {
if (confirm("真的要删除吗？")){
return true;
}else{
return false;
}
}
</script>
</body>
</html>
在创建一个se'rvice的包，courseservice.java
package service;
import java.util.List;
import dao.CourseDao;
import entity.Course;
/**
* CourseService
* 服务层
* @author Hu
*
*/
public class CourseService {
CourseDao cDao = new CourseDao();
/**
* 添加
* @param course
* @return
*/
public boolean add(Course course) {
boolean f = false;
if(!cDao.name(course.getName())) {
cDao.add(course);
f = true;
}
return f;
}
/**
* 删除
*/
public void del(int id) {
cDao.delete(id);
}
/**
* 修改
* @return
*/
public void update(Course course) {
cDao.update(course);
}
/**
* 通过ID得到一个Course
* @return
*/
public Course getCourseById(int id) {
return cDao.getCourseById(id);
}
/**
* 通过Name得到一个Course
* @return
*/
public Course getCourseByName(String name) {
return cDao.getCourseByName(name);
}
/**
* 查找
* @return
*/
public List<Course> search(String name, String riqi) {
return cDao.search(name,riqi);
}
/**
* 全部数据
* @return
*/
public List<Course> list() {
return cDao.list();
}
}
最后创建一个servlet的包 courseservlet.java
package servlet;
import java.io.IOException;
import java.util.List;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import entity.Course;
import service.CourseService;
@WebServlet("/CourseServlet")
public class CourseServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
CourseService service = new CourseService();
/**

}
}
/**

private void add(HttpServletRequest req, HttpServletResponse resp) throws IOException, ServletException {

//添加后消息显示

}
}
/**

}
/**

req.setAttribute("course", course);
req.getRequestDispatcher("detail2.jsp").forward(req,resp);
}
/**

*/
private void getCourseByName(HttpServletRequest req, HttpServletResponse resp) throws IOException, ServletException{
req.setCharacterEncoding("utf-8");
String name = req.getParameter("name");
Course course = service.getCourseByName(name);
if(course == null) {
req.setAttribute("message", "查无此货物！");
req.getRequestDispatcher("del.jsp").forward(req,resp);
} else {

req.getRequestDispatcher("detail.jsp").forward(req,resp);
}
}
/**

private void del(HttpServletRequest req, HttpServletResponse resp) throws IOException, ServletException{

}
/**

private void update(HttpServletRequest req, HttpServletResponse resp) throws IOException, ServletException{

String name = req.getParameter("name");
String changjia = req.getParameter("changjia");

String riqi =req.getParameter("riqi");
String shijian = req.getParameter("shijian");
String danwei = req.getParameter("danwei");

Course course = new Course(id, name,changjia,type,guige,shuliang,riqi,shijian,danwei,people);
service.update(course);
req.setAttribute("message", "修改成功");
req.getRequestDispatcher("CourseServlet?method=list").forward(req,resp);
}
/**

List<Course> courses = service.search(name, riqi);
req.setAttribute("courses", courses);
req.getRequestDispatcher("searchlist.jsp").forward(req,resp);
}
}
然后对于jsp的的源代码

总结：
对于这个库存物资管理系统，总体来说，比上周有一些的进步，这次是独自做出来的，虽然是仿造上周学长给的模板来做的，但是好歹做出来了，又一些瑕疵，比如对于出入库的时间人物，我觉得应该用两个表，分别入库和出库，但是不怎么会做，所以只制作了一个表。通过今天的做这个库存物资管理系统，也懂了一些关于java web的知识，学会了如何Java连接数据库，但对于增删改查的具体操作，还是不怎么了解，还有些茫然，但是我会在以后的课余时间，来学习它，争取把它搞明白，最后独自来做一个系统。
