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();
	
	/**
	 * 方法选择
	 */
	protected void service(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
		req.setCharacterEncoding("utf-8");
		String method = req.getParameter("method");
		if ("add".equals(method)) {
			add(req, resp);
		} else if ("del".equals(method)) {

		} else if ("list".equals(method)) {
			list(req, resp);
		}
	}

	/**

			req.setAttribute("message", "添加成功");
			req.getRequestDispatcher("add.jsp").forward(req,resp);
		} else {

		}
	}
	
	/**

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

		List<Course> courses = service.list();
		req.setAttribute("courses", courses);
		req.getRequestDispatcher("list.jsp").forward(req,resp);
	}

	/**
	 * 通过ID得到Course
	 * @param req
	 * @param resp
	 * @throws ServletException 
	 */
	private void getCourseById(HttpServletRequest req, HttpServletResponse resp) throws IOException, ServletException{
		req.setCharacterEncoding("utf-8");
		int id = Integer.parseInt(req.getParameter("id"));
		Course course = service.getCourseById(id);
		req.setAttribute("course", course);
		req.getRequestDispatcher("detail2.jsp").forward(req,resp);
	}

	/**
	 * 通过名字查找
	 * 跳转至删除
	 * @param req

		if(course == null) {

			req.getRequestDispatcher("del.jsp").forward(req,resp);
		} else {
			req.setAttribute("course", course);
			req.getRequestDispatcher("detail.jsp").forward(req,resp);
		}
	}
	
	/**
	 * 删除
	 * @param req
	 * @param resp
	 * @throws IOException
	 * @throws ServletException 
	 */
	private void del(HttpServletRequest req, HttpServletResponse resp) throws IOException, ServletException{

		int id = Integer.parseInt(req.getParameter("id"));
		service.del(id);
		req.setAttribute("message", "删除成功!");
		req.getRequestDispatcher("del.jsp").forward(req,resp);
	}
	
	/**
	 * 修改
	 * @param req
	 * @param resp
	 * @throws IOException
	 * @throws ServletException 
	 */
	private void update(HttpServletRequest req, HttpServletResponse resp) throws IOException, ServletException{
		req.setCharacterEncoding("utf-8");
		int id = Integer.parseInt(req.getParameter("id"));
		String name = req.getParameter("name");

		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。
