（1）工程目录：

（2）StudentEntity 利用Hibernate自动生成实体类

package com.student.sys.entity;

import javax.persistence.*;

@Entity
@Table(name = "student", schema = "sm", catalog = "")
public class StudentEntity {
   private int studentId;
   private String studentName;
   private String studentNumber;
   private String studentScore;

   @Id
   @Column(name = "student_id")
   public int getStudentId() {
      return studentId;
   }

   public void setStudentId(int studentId) {
      this.studentId = studentId;
   }

   @Basic
   @Column(name = "student_name")
   public String getStudentName() {
      return studentName;
   }

   public void setStudentName(String studentName) {
      this.studentName = studentName;
   }

   @Basic
   @Column(name = "student_number")
   public String getStudentNumber() {
      return studentNumber;
   }

   public void setStudentNumber(String studentNumber) {
      this.studentNumber = studentNumber;
   }

   @Basic
   @Column(name = "student_score")
   public String getStudentScore() {
      return studentScore;
   }

   public void setStudentScore(String studentScore) {
      this.studentScore = studentScore;
   }

   @Override
   public boolean equals(Object o) {
      if (this == o) return true;
      if (o == null || getClass() != o.getClass()) return false;

      StudentEntity that = (StudentEntity) o;

      if (studentId != that.studentId) return false;
      if (studentName != null ? !studentName.equals(that.studentName) : that.studentName != null) return false;
      if (studentNumber != null ? !studentNumber.equals(that.studentNumber) : that.studentNumber !&
