庫存物資管理系統javascript
1.首先先創建一個名爲course的數據庫，在創建一個course名的表，而後添加幾個字段
html
項目目錄結構java
2.源代碼mysql
先創建一個util的包，建立一個DBUtil的類，這是肯定的，DBUtil.javaweb
package util;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
/**
* 數據庫鏈接工具
* @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");//加載驅動
conn = DriverManager.getConnection(db_url, db_user, db_pass);
} catch (Exception e) {
e.printStackTrace();
}
return conn;
}
/**
* 關閉鏈接
* @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();
}
}
}
}
而後添加建立一個course的類，定義變量。course.javasql
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;
}
}
而後創建一個Dao層，來封裝數據，實現增刪改查，courseDao.java數據庫
<%@ 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;">庫存物資信息刪除</h1>
<a href="index.jsp">返回主頁</a>
<table class="tb">
<tr>
<td>商品名稱</td>
<td>${course.name}</td>
</tr>
<tr>
<td>廠家</td>
<td>${course.changjia}</td>
</tr>
<tr>
<td>型號</td>
<td>${course.type}</td>
</tr>
<tr>
<td>規格</td>
<td>${course.guige}</td>
</tr>
<tr>
<td>數量</td>
<td>${course.shuliang}</td>
</tr>
<tr>
<td>日期</td>
<td>${course.riqi}</td>
</tr>
<tr>
<td>時間</td>
<td>${course.shijian}</td>
</tr>
<tr>
<td>單位</td>
<td>${course.danwei}</td>
</tr>
<tr>
<td>收送貨人姓名</td>
<td>${course.people}</td>
</tr>
</table>
<div class="a">
<a onclick="return check()" href="CourseServlet?method=del&id=${course.id}">刪 除</a>
</div>
</div>
<script type="text/javascript">
function check() {
if (confirm("真的要刪除嗎？")){
return true;
}else{
return false;
}
}
</script>
</body>
</html>
在建立一個se'rvice的包，courseservice.javajsp
package service;
import java.util.List;
import dao.CourseDao;
import entity.Course;
/**
* CourseService
* 服務層
* @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;
}
/**
* 刪除
*/
public void del(int id) {
cDao.delete(id);
}
/**
* 修改
* @return
*/
public void update(Course course) {
cDao.update(course);
}
/**
* 經過ID獲得一個Course
* @return
*/
public Course getCourseById(int id) {
return cDao.getCourseById(id);
}
/**
* 經過Name獲得一個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);
}
/**
* 所有數據
* @return
*/
public List<Course> list() {
return cDao.list();
}
}
最後建立一個servlet的包 courseservlet.java工具
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 {

}
}
/**

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", "查無此貨物！");
req.getRequestDispatcher("del.jsp").forward(req,resp);
} else {

}
}
/**

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

}
/**

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

String shijian = req.getParameter("shijian");
String danwei = req.getParameter("danwei");
String people = req.getParameter("people");
Course course = new Course(id, name,changjia,type,guige,shuliang,riqi,shijian,danwei,people);
service.update(course);

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);
}
}
而後對於jsp的的源代碼post

總結：
對於這個庫存物資管理系統，整體來講，比上週有一些的進步，此次是獨自作出來的，雖然是仿造上週學長給的模板來作的，可是好歹作出來了，又一些瑕疵，好比對於出入庫的時間人物，我以爲應該用兩個表，分別入庫和出庫，可是不怎麼會作，因此只製做了一個表。經過今天的作這個庫存物資管理系統，也懂了一些關於java web的知識，學會了如何Java鏈接數據庫，但對於增刪改查的具體操做，仍是不怎麼了解，還有些茫然，可是我會在之後的課餘時間，來學習它，爭取把它搞明白，最後獨自來作一個系統。
