代码如下：Book.java:

package bean;

public class Book {

	private String name;
	private int price;
	private int bookid;

	public int getBookid() {
		return bookid;
	}

	public void setBookid(int bookid) {
		this.bookid = bookid;
	}

	public String getName() {
		return name;
	}

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

	public int getPrice() {
		return price;
	}

	public void setPrice(int price) {
		this.price = price;
	}

	public Book(String name, int price, int bookid) {
		super();
		this.name = name;
		this.price = price;
		this.bookid = bookid;
	}

}

ChaoAction.java:

package chao;

import java.util.ArrayList;
import java.util.List;

import bean.Book;

public class ChaoAction {
	private String name;
	private List books;

	public List getBooks() {
		return books;
	}

	public void setBooks(List books) {
		this.books = books;
	}

	public String getName() {
		return name;
	}

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

	public String execute() {
		books=new ArrayList();
		books.add(new Book("javaweb1",34,1));
		books.add(new Book("javaweb2",322,2));
		books.add(new Book("javaweb3",67,3));
		name = "chao";
		return "list";
