二、核心代码说明

查看所有图书信息：

package com.ly.action;

import java.util.List;

import java.util.Map;

import org.apache.struts2.interceptor.RequestAware;

import com.ly.bean.LyBook;

import com.ly.service.LyBookSer;

public class LyBookAction implements RequestAware { private LyBookSer BookSer;

private int sencond;

private int first;

private int bookid;

public void setBookid(int bookid) {

this.bookid = bookid;

}

public void setFirst(int first) {

this.first = first;

}

public void setSencond(int sencond) {

this.sencond = sencond;

}

public void setBookSer(LyBookSer bookSer) { BookSer = bookSer;

}

public String getAll(){

List list = BookSer.getAll();

map.put("booklist", list);

return "success";

}

private Map map;

public void setRequest(Map arg0) {

this.map = arg0;

}

根据图书id查看：

public String detail(){

map.clear();

BookSer.detail(bookid);

List list = BookSer.detail(bookid);

map.put("booklist", list);

return"detail";

}

}

public List detail(int id){

String sql="from LyBook where bookid= "+id;

List list =(List) getsSession().createQuery(sql).list();

return list;

}

public List detail(int bookid){ return Bookdao.detail(bookid);

}

根据ID删除：

private int bookid;

public void setBookid(int bookid) {

this.bookid = bookid;

}

public String delete(){

BookSer.delete(bookid);

return"delete";

}

public void delete(int bookid){

Bookdao.delete(bookid);

}

public void delete(int bookid){

String sql="delete from LyBook where bookid=?";

getsSession().createQuery(sql).setInteger(0,

bookid).executeUpdate();

}

根据id修改图书信息：

public String update1(){

BookSer.detail(bookid);

List list = BookSer.detail(bookid);

map.put("booklist", list);

return"update";

}

public String update(){

BookSer.update(bookid, price, bookname, conutNum, author);

return"delete";

}

public void update(int bookid,double price,String bookname,int conutNum,String author){

String sql="update LyBook set price="+price+"where bookid="+bookid;

getsSession().createQuery(sql).executeUpdate();

}

添加图书：

public void addbook(LyBook book){

getsSession().saveOrUpdate(book);

}

public void addbook(LyBook book){

Bookdao.addbook(book);

}

}

private String bookname;

private int conutNum;

private double price;

private String author;

public void setBookname(String bookname) { this.bookname = bookname;

}

public void setPrice(double price) {

this.price = price;

}

public void setAuthor(String author) { this.author = author;

}

public void setConutNum(int conutNum) { this.conutNum = conutNum;

}

public String addbook(){

LyBook book = new LyBook();

book.setBookname(bookname);

book.setConutNum(conutNum);

book.setPrice(price);

book.setAuthor(author);

BookSer.addbook(book);

return"delete";

}
