Question

我有一个jsp页面和一个类。我试图在jsp页面中使用该类的信息。这是代码：

<?xml version="1.0" encoding="ISO-8859-1" ?>
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%@ page import="user.Customer" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" />
<title>Insert title here</title>
</head>
<body>

<h1>Main Menu</h1>
<% session.setAttribute("username", Globals.customer.getUsername());
   session.setAttribute("password", Globals.customer.getPassword());
   session.setAttribute("name", Globals.customer.getName());
   session.setAttribute("surname", Globals.customer.getSurname());
   session.setAttribute("phone", Globals.customer.getPhone());
   session.setAttribute("address", Globals.customer.getAddress());
   session.setAttribute("email", Globals.customer.getEmail());%>
<a href="editinfo.jsp">Edit your personal information</a>
</body>
</html>

全球类：

import user.Customer;


public class Globals {

public static Customer customer;

}

客户类：

package user;

public class Customer {

public Customer(){}

public Customer(String username,String password,String name,String surname,String phone,String address,String email){
    this.username=username;
    this.password=password;
    this.name=name;
    this.surname=surname;
    this.phone=phone;
    this.address=address;
    this.email=email;
}

private String username;
private String password;
private String name;
private String surname;
private String phone;
private String address;
private String email;


public String getName(){
    return name;
}
public String getSurname(){
    return surname;
}
public String getUsername(){
    return username;
}
public String getPassword(){
    return password;
}
public String getEmail(){
    return email;
}
public String getPhone(){
    return phone;
}
public String getAddress(){
    return address;
}


}

以下是我的工作：当用户登录时，我首先通过设置用户名，电子邮件等创建一个Customer对象，然后将其添加到当前会话中。但是在行

session.setAttribute("username", Globals.customer.getUsername()

它给出了一个错误说

An error occurred at line: 14 in the jsp file: /main.jsp
Globals cannot be resolved
11: <body>
12: 
13:     <h1>Main Menu</h1>
14:     <% session.setAttribute("username", Globals.customer.getUsername());
15:        session.setAttribute("password", Globals.customer.getPassword());
16:        session.setAttribute("name", Globals.customer.getName());
17:        session.setAttribute("surname", Globals.customer.getSurname());

任何人都可以帮我吗？感谢

Answer 1

使用页面指令或通过Globals类扩展该jsp页面即<%@page import="package.Globals" %>
包是你的包的名称..

Answer 2

导入您的Globals课程

<%@ page import="user.Customer" %>
<%@ page import="path.to.Globals" %>

或使用单一页面指令进行导入，例如

<%@ page import="user.Customer,path.to.Globals" %>

在jsp页面中无法解析类
