我不熟悉春天和冬眠。我读了一些关于它们的文章，并尝试制作一个简单的程序，在这个程序中，用户输入用户名和密码，然后根据这个页面直接进入欢迎页面。我能够登录页面，但在从数据库读取数据时遇到问题

Student.java

package com.nakul;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;

@Entity
@Table(name = "user")
public class Student {
    @Column(name = "uname")
    private String name;
    private String password;

    @Id
    @Column(name = "uid")
    private int id;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

}

StudentDAO.java

package com.nakul;

import java.util.List;

public interface StudentDAO {

    public List<Student> listStudent();
}

有人能帮我纠正一下吗
