2020年第二次实训

创建项目重要步骤

（1）创建Java项目
注意项目名称
（2）在项目里创建文件夹
在项目根目录创建help、images、lib三个文件夹3、在lib里添加MySQL数据库驱动程序包
4.添加图片并赋予自己的班级名字

创建实体类

1、创建学校实体类对应学校表

package net.hw.student.bean;

import java.util.Date;

功能：学校实体类

public class College {
private int id; // 学校标识符
private String name; // 学校名称
private String president; // 校长
private Date startTime; // 建校时间
private String telephone; // 联系电话
private String email; // 电子邮箱
private String address; // 通信地址
private String profile; // 学校简介

public int getId() {
    return id;
}

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

public String getName() {
    return name;
}

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

public String getPresident() {
    return president;
}

public void setPresident(String president) {
    this.president = president;
}

public Date getStartTime() {
    return startTime;
}

public void setStartTime(Date startTime) {
    this.startTime = startTime;
}

public String getTelephone() {
    return telephone;
}

public void setTelephone(String telephone) {
    this.telephone = telephone;
}

public String getEmail() {
    return email;
}

public void setEmail(String email) {
    this.email = email;
}

public String getAddress() {
    return address;
}

public void setAddress(String address) {
    this.address = address;
}

public String getProfile() {
    return profile;
}

public void setProfile(String profile) {
    this.profile = profile;
}

@Override
public String toString() {
    return "College{" +
            "id=" + id +
            ", name='" + name + '\'' +
            ", president='" + president + '\'' +
            ", startTime=" + startTime +
            ", telephone='" + telephone + '\'' +
            ", email='" + email + '\'' +
            ", address='" + address + '\'' +
            ", profile='" + profile + '\'' +
            '}';
}

}

}

public String getAuthor() {
    return author;
}

public void setAuthor(String author) {

public String getTelephone() {
    return telephone;
}

    this.address = address;
}

public String getEmail() {
    return email;
}

public void setEmail(String email) {
    this.email = email;
}

@Override
public String toString() {
    return "Status{" +
