1.将user对象存入session

request.getSession().setAttribute("user", userSession);

2.User类

public class User {
        private String userId;
    
        private String userName;
    
        private String userPassword;
    
        private String userEmail;
    
        private String userPhoto;
    
        public String getUserId() {
            return userId;
        }
    
        public void setUserId(String userId) {
            this.userId = userId == null ? null : userId.trim();
        }
    
        public String getUserName() {
            return userName;
        }
    
        public void setUserName(String userName) {
            this.userName = userName == null ? null : userName.trim();
        }
    
        public String getUserPassword() {
            return userPassword;
        }
    
        public void setUserPassword(String userPassword) {
            this.userPassword = userPassword == null ? null : userPassword.trim();
        }
    
        public String getUserEmail() {
            return userEmail;
        }
    
        public void setUserEmail(String userEmail) {
            this.userEmail = userEmail == null ? null : userEmail.trim();
        }
    
        public String getUserPhoto() {
            return userPhoto;
        }
    
        public void setUserPhoto(String userPhoto) {
            this.userPhoto = userPhoto == null ? null : userPhoto.trim();
        }
    }

3.jsp页面通过JSTL表达式获取 （

1.确保引入了JSTL所需jar包；

2.jsp页面引入jstl表达式 <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>）

<td>${sessionScope.user.getUserId()}</td>
     <td>${sessionScope.user.getUserName()}</td>
      <td>${sessionScope.user.getUserEmail()}</td>
