mymvcdemo是自定义mvc框架的使用示例

1.1 实体类

package com.zking.mymvc.entity;

import java.io.Serializable;

public class Book implements Serializable {
	
	private Integer bookid;
	
	private String bookname;
	
	private String bookname_pinyin;
	
	private Float price;
	
	private String booktype;
	
	public Integer getBookid() {
		return bookid;
	}
	public void setBookid(Integer bookid) {
		this.bookid = bookid;
	}
	public String getBookname() {
		return bookname;
	}
	public void setBookname(String bookname) {
		this.bookname = bookname;
	}
	public String getBookname_pinyin() {
		return bookname_pinyin;
	}
	public void setBookname_pinyin(String bookname_pinyin) {
		this.bookname_pinyin = bookname_pinyin;
	}
	public Float getPrice() {
		return price;
	}
	public void setPrice(Float price) {
		this.price = price;
	}
	public String getBooktype() {
		return booktype;
	}
	public void setBooktype(String booktype) {
		this.booktype = booktype;
	}
	
	public Book() {
		// TODO Auto-generated constructor stub
	}
	public Book(Integer bookid, String bookname, String bookname_pinyin, Float price, String booktype) {
		super();
		this.bookid = bookid;
		this.bookname = bookname;
		this.bookname_pinyin = bookname_pinyin;
		this.price = price;
		this.booktype = booktype;
	}
	
	public Book( String bookname, String bookname_pinyin, Float price, String booktype) {
		this.bookname = bookname;
		this.bookname_pinyin = bookname_pinyin;
		this.price = price;
		this.booktype = booktype;
	}
	@Override
	public String toString() {
		return "Book [bookid=" + bookid + ", bookname=" + bookname + ", bookname_pinyin=" + bookname_pinyin + ", price="
				+ price + ", booktype=" + booktype + "]";
	}
