jsp页面通过JSTL表达式获取session中存储的对象的属性

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>
