1.定义实体类

package bean;

public class book {

    

private String bookname;

private String bookwriter;

private int price;

private String pic;

public void setBookname(String bookname) {

    this.bookname = bookname;

}

public String getBookname() {

    return bookname;

}

public void setBookwriter(String bookwriter) {

    this.bookwriter = bookwriter;

}

public String getBookwriter() {

    return bookwriter;

}

public void setPrice(int price) {

    this.price = price;

}

public int getPrice() {

    return price;

}

public void setPic(String pic) {

    this.pic = pic;

}

public String getPic() {

    return pic;

}

}

 

 

2.action

package action;

import java.sql.ResultSet;

import java.util.ArrayList;

import java.util.List;

import DAO.dao;

import bean.book;

import com.opensymphony.xwork2.ActionSupport;

public class display extends ActionSupport{

    private List<book> bk;

    private List<book> bk1=new ArrayList<book>();

    private ResultSet rs=null;

    

    public void setBk(List<book> bk) {

        this.bk = bk;

    }

    public List<book> getBk() {

        return bk;

    }

    

    public String execute()throws Exception

    {

        dao da =new dao();

        rs=da.displaydata();

        

        while(rs.next())

        {

        book bk2=new book();

        bk2.setBookname(rs.getString("bookname"));

        bk2.setBookwriter(rs.getString("bookwriter"));

        bk2.setPrice(rs.getInt("price"));

        bk2.setPic(rs.getString("pic"));

        bk1.add(bk2);

        

        }

        this.setBk(bk1);

        return "sucess";

    }

}

3.Struts.xml 配置

        <action name="display" class="action.display">

            <result name="sucess">

            /display.jsp

            </result>

       </action>

4.jsp显示

    <s:iterator value="bk">

书名：    <s:property value="bookname"/><br>

作者：    <s:property value="bookwriter"/><br>

价格：    <s:property value="price"/><br>

简介：    <s:property value="pic"/><br>

    <br><br><br><br>

    </s:iterator>
