用Springboot实现学生CRUD操作（含前端页面，含分页，自定义SQL）

1..编写entity包下实体类Student

（一个Javabean规范）

package com.example.stu.kudestu.stu.entity;

import javax.persistence.*;

@Entity
@Table(name = "student")
//@Entity  应用在实体类上   @Table(name = "student") 应用在实体类上,并且name属性为数据库表名
public class Student {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY) //ID自增
    private  Integer id;
    private String name;
    private  int age;
    private  String sex;

    @Override
    public String toString() {
        return "Student{" +
                "id=" + id +
                ", name='" + name + '\'' +
                ", age=" + age +
                ", sex='" + sex + '\'' +
                '}';
    }

    public Student() {
    }

    public Integer getId() {
        return id;
    }

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

    public String getName() {
        return name;
    }

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

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public String getSex() {
        return sex;
    }

    public void setSex(String sex) {
        this.sex = sex;
    }
}
