在java中每周安排一份工作

Question

我有一个java web应用程序，我在使用java文件时做了mysql连接，我想在我的Web应用程序中每周安排一个作业。

这是我的java文件示例

public class DbFunction {

    public static DataSource dataSource;

    public static Connection getConnection_4main() throws SQLException {

        Connection connection = null;
        System.out.println("Cant create a Connection");
        connection = DriverManager.getConnection("jdbc:mysql://localhost:3306/" + Constants.TC_DB_NAME + "", "root",
                "mysql");
        return connection;
    }
}

我的jsp文件在这里

<%@page import="net.sf.json.JSONArray"%>
<%@ page import= "java.sql.*" %>
<%@ page import= "java.util.*"%>
<%@page trimDirectiveWhitespaces="true"%>
<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<jsp:useBean id= "dbfunc" scope="session" class= "package.DbFunction" />
<%
try{    
String dailyscheduleidlist=request.getParameter("dailyscheduleidlist");
String []dailyscheduleidarray=dailyscheduleidlist.split("_"); 
boolean b = dbfunc.removeDailyScheduleBulk(dailyscheduleidarray);    
out.print(b);
}
catch(Exception ex){    
    throw ex;
}
finally
{   
}   
%>
