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>
