手把手做一个JSP入门程序（四）：商品实体类设计（JSP）

商品实体类设计

  这里的商品实例也就是书籍。我们会将其构建为一个JavaBean类，以提高代码的重复利用性和程序的可维护性。这里有个小技巧用于迅速添加大量的setter和getter：右键你的类名，然后在弹出菜单中选择：”Source” -> “Generate Getters and Setters” -> “Select All” -> “OK”。

package entity;

import java.util.Date;

public class Book {
//  书籍的相关属性,这里需要设置为私有权限
private String isbn;
private String name;
private String author;
private String intro; //书籍简介
private float price_original;
private float price;
private String publish_comany;
private Date publish_time;
private String img_path;

//  共有无参构造函数
public Book(){
}

//  所有属性的getter和setter
public String getIsbn() {
return isbn;
}
public void setIsbn(String isbn) {
this.isbn = isbn;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getAuthor() {
return author;
}
public void setAuthor(String author) {
this.author = author;
}
public String getIntro() {
return intro;
}
public void setIntro(String intro) {
this.intro = intro;
}
public float getPrice_original() {
return price_original;
}
public void setPrice_original(float price_original) {
this.price_original = price_original;
}
public float getPrice() {
return price;
}
public void setPrice(float price) {
this.price = price;
}
public String getPublish_comany() {
return publish_comany;
}
public void setPublish_comany(String publish_comany) {
this.publish_comany = publish_comany;
}
public Date getPublish_time() {
return publish_time;
}
public void setPublish_time(Date publish_time) {
this.publish_time = publish_time;
}
public String getImg_path() {
return img_path;
}
public void setImg_path(String img_path) {
this.img_path = img_path;
}
}
