html实现宿舍管理系统,宿舍管理系统部分代码实现
目錄結構：
連接數據庫功能代碼實現：
package com.db;
import java.sql.*;
public class DBHelper {
private String dbUrl="jdbc:mysql://localhost:3306/sushe";
private String dbUser="root";
private String dbPassword="123456";
private String jdbcName="com.mysql.jdbc.Driver";
public Connection getConn(){
Connection conn = null;
try{
Class.forName(jdbcName);
}
catch(Exception e){}
try{
conn=DriverManager.getConnection(dbUrl,dbUser,dbPassword);
}
catch(SQLException ex){}
return conn;
}
public static void main(String[] args)
{
System.out.println(new DBHelper().getConn());
}
}

public class PasswordUpdateSave extends ActionSupport {
//下面是Action內用于封裝用戶請求參數的屬性
private String Password;
private String Password2;
private String Msg;
public String getPassword() {
return Password;
}
public void setPassword(String password) {
Password = password;
}
public String getPassword2() {

}
public void setPassword2(String password2) {
Password2 = password2;
}
public String getMsg() {
return Msg;
}
public void setMsg(String msg) {

}
//處理用戶請求的execute方法
public String execute() throws Exception {
//解決亂碼，用于頁面輸出
HttpServletResponse response=null;
response=ServletActionContext.getResponse();
response.setContentType("text/html;charset=UTF-8");
response.setCharacterEncoding("UTF-8");
PrintWriter out = response.getWriter();
//創建session對象
HttpSession session = ServletActionContext.getRequest().getSession();
//驗證是否正常登錄
if(session.getAttribute("id")==null){
out.print("");
out.flush();out.close();return null;
}
String type=session.getAttribute("type").toString();
if(type.equals("1"))//校園管理員身份
{
//查詢原密碼是否正確

return INPUT;
}
}
else
{
out.print("");
out.flush();out.close();return null;
}
}
//判斷是否空值
private boolean isInvalid(String value) {
return (value == null || value.length() == 0);
}
//測試
public static void main(String[] args) {
System.out.println();

學生入住界面代碼實現：
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
校園宿舍管理系統function mycheck(){
if(isNull(form1.Building_ID.value)){
alert("請選擇樓宇！");
return false;
}
if(isNull(form1.Domitory_ID.value)){
alert("請選擇寢室！");
return false;

if(isNull(form1.Student_Username.value)){
alert("請輸入學生學號！");
return false;
}
}
function isNull(str){
if ( str == "" ) return true;
var regu = "^[ ]+$";
var re = new RegExp(regu);
return re.test(str);
